Utility Escalation Rate MethodologyExecutive SummaryGiven the volatility of energy prices (electricity, natural gas, fuel oil, etc.) and the many variablesthat these prices depend on, it is often a difficult task to determine the correct utility escalationrates to be used in performance contracts. However, there is a great deal of research done bythe Department of Energy’s Energy Information Administration (EIA) to forecast the future pricesof energy. The latest projections for electricity and various fuels (natural gas, fuel oil, coal, etc.)are shown in the graph below:Four colored points for 2009 are from the EIAShort Term Energy Outlook (STEO) on 10/6/09for Electricity, Propane, FO2, FO6, Natural Gas.EIA Historical and Forecasted Fuel Prices (Dec08)Commercial + Industrial Averagein Nominal (Year by Year) Dollars per MMBTU50.0Last Updated: 11/10/0945.0Propane40.035.0ElectricityFO2Price ($/MMBTU)30.025.020.0FO615.0Nat Gas10.0Corn (via USDA)Wood5.00.0CoalTDFPet Coke198619871988198919901991199219931994199519961997199819992000200120022003200420052006200720082009201020112012201320142015201620172018201920202021202220232024202520262027202820292030Year© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.38

The National Institute of Standards and Technology (NIST) use these projections from the EIAto determine escalation rate factors specifically for performance contracts. These factors aretabulated and organized by census region, energy type, and sector (commercial or industrial).NIST has also developed a tool called the “Energy Escalation Rate Calculator” which takes theinformation for a specific project (location, duration, energy savings, etc.) and looks up theescalation rate factors from the tables. Johnson Controls uses this tool to determine the energyescalation rates for each project individually. The section below provides the escalation ratecalculation methodology in greater detail.Energy Escalation Rate Calculator (developed by NIST)The Energy Escalation Rate Calculator (EERC) computes an average annual escalation rate forfuel prices, based on the annual energy price forecasts of the Energy Information Administration(EIA) of the U.S. Department of Energy (DOE). This rate is used to escalate the contractpayments in Energy Savings Performance Contracts (ESPC) and Utility Energy ServicesContracts (UESC) when the payments are based on the projected annual energy cost savings.The rate is weighted by the share of each of the energy types used in the project.In the life-cycle cost methodology and software of the DOE Federal Energy ManagementProgram (FEMP), the base-year energy costs are escalated from year to year at rates projectedby EIA to arrive at the total energy cost over a given period. The escalation rates, e, areprojected by Census Region, energy type, and industrial sector and vary from year to year. Theformula used to calculate total energy costs is:whereCA1 e A1 e 1 e A … 1 e 1 e …1e AC is the undiscounted sum total of future energy costs,A is the base-year annual cost,ei is the annual escalation rate, which varies from year to yearn is the number of years in the proposed study periodWhen the escalation rate is the same in each year of the study period, the series can besimplified to the Uniform Compound Amount formula:F 1 i 1Ai© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.39

whereF is the future value of the series,i is the interest rate,t is the length of the series.A is the base-year annual costSince a uniform escalation rate is needed to compute the contract payments in ESPC andUESC projects, the EERC uses the Uniform Compound Amount formula to approximate thetotal energy costs over the period, as calculated with EIA rates, and iteratively solves for theinterest rate, i, the average annual escalation rate. The relationship between the UniformCompound Amount factor and the variable EIA rates in the series can be expressed as followsfor a project of n years duration:1 e 1 11 e 1 e 1 e … 1 e 1 e …1e e The EERC prompts the user for information on the share of cost savings attributable to eachfuel type, project location, industry sector, and the beginning date and duration of theperformance period or contract term. It then retrieves the relevant energy price forecasts fromthe DOE/EIA database and computes the average escalation rate, as described above. If theperformance period begins later than the base date, the calculated average rate includes theprice escalation for the intermediate years.The calculated average escalation rate is reported in both real (excluding inflation) and nominal(including inflation) terms. The EIA energy price projections exclude inflation and thus generatereal rates. The inflation rate is an input to this tool, and is determined by the Office ofManagement and Budget (OMB). The OMB published data can be found in OMB Circular A-94,Appendix C. The table below describes the estimated inflation rates determined by TreasuryNotes and Bonds with maturities ranging from 3 to 30 years, the contract period determineswhich inflation rate to be used:Maturity 3-year 5-year 7-year 10-year 30-yearRate 0.9% 1.6% 1.9% 2.4% 2.7%© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.40

To calculate the nominal escalation rate, which includes inflation, the calculator uses thefollowing relationship:r 1 r 1 r f 1The calculated average annual escalation rate, eavg, when applied to the base-year energycosts or savings of ESPC or UESC projects, results in approximately the same undiscountedtotal amounts over the contract period as do the EIA-projected variable rates. If more than onefuel is used in the project, the EERC weights the average escalation rate according to theproportions stated by the user.Calculated Utility Escalation RatesBased on the analysis described above the following utility escalation rates have beencalculated.Name ofSchoolEnergyElectric Consumption Annual Electric Demand Natural GasEscalationRateStart YearofEscalationEscalationRateStart YearofEscalationEscalationRateStart YearofEscalationSpotswoodHigh SchoolMemorialMiddleSchoolApplebyElementarySchoolSchoenlyElementarySchool5.09% Year 1 5.09% Year 1 5.83% Year 15.09% Year 1 5.09% Year 1 5.83% Year 15.09% Year 1 5.09% Year 1 5.83% Year 15.09% Year 1 5.09% Year 1 5.83% Year 1© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.41

Multi-Year Utility Rate AnalysisIn order to validate the escalation rates calculated using the EERC tool, Johnson Controls hasevaluated the change in utility rates for Spotswood Public Schools for the previous years.The graph below indicates that the marginal electric rates have changed very little over thecourse of two years.

The graph above indicates that the natural gas utility rate has decreased over the course ofthree years. On the average the gas rate from 2010 to 2011 is about 12% less than the gasrate from 2008 to 2009. Although the past three years indicate a decrease in gas marginalrates, a longer term analysis could indicate an overall escalation in price.$1.80$1.60$1.40$1.20$1.00$0.80$0.60$0.40$0.20$0.00Gas Utility Rates from 2008 to 2011Total $/ therm3-Year Gas Utility Rate Comparison© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.43

Boiler Plant MeasuresBoiler ReplacementsFIM SummaryHot water boilers are used to provide heating to the classrooms and office areas throughout abuilding. In schools where the boilers are very old and in a poor shape, replacement of existingboilers with a similar number of new high-efficiency units will provide efficiency gains that willgenerate substantial operating and fuel cost savings. The radiant and convective heat losseswill also be reduced with the installation of new boilers which makes the entire hot water systemmore efficient. Where applicable, the hot water boilers that are recommended for replacementwill be replaced by condensing hot water boilers capable of 95% overall efficiencies (includingthermal and combustion losses).In some cases, a single boiler may provide all the heating for a building with no source ofheating back-up. Replacement of the single boiler in these boiler plants with multiple new, highefficiencyunits will generate significant energy savings as well as provide redundancy to theheating system. Each new boiler will be slightly smaller than the existing single boiler but as awhole the central plant will meet or exceed the heating capacity of the current boiler. Theinstallation of the smaller boilers will increase the efficiency of the entire plant by operating moreefficiently at low loads than the single boiler.Facilities Recommended for this Measure• Memorial Middle School• Schoenly Elementary SchoolScope NarrativeThe original section of Memorial Middle School is served by asingle Cleaver Brooks boiler which was installed in 1969 at thetime of construction. This boiler has exceeded the ASHRAErated life of the equipment and should be replaced with a moreefficient boiler system.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.51

In order to provide the most efficient hot water system as well as redundancy for the building,two AERCO Benchmark boilers have been selected to replace the existing boiler. AERCOcondensing boilers are recommended because the brand is already installed in the new sectionof the Middle School and will make maintaining the equipment less of a burden for the District.Schoenly Elementary School was constructed in two major phases; the original building waserected in 1958 and the newer section was added in 2004. The original section contains an H.B.Smith hot water boiler which was installed when the building was built and has exceeded itsASHRAE rated life. Due to the age and condition of this boiler replacement with two new, highefficiency boilers is recommended. In order to provide added redundancy to the school servedby this hot water system, two AERCO MODULEX boilers are recommended for installation toreplace the single H.B. Smith boiler.In both Memorial Middle School and Schoenly Elementary School, the two new boilers will besized for 65% of the load of the building. In most cases a single boiler will be able to handle theheating load of the building and during colder temperatures the additional boiler will assist inmeeting the load. By installing multiple smaller boilers, the heating plant will operate moreefficiently on part-load days and will provide significant fuel savings throughout the year. Theboilers will also be supplied with AERCO boiler controllers which will allow the system tooperate as efficiently as possible. AERCO controllers will be tied into the recommended districtwideMetasys building automation system in order to monitor the status of the hot water heatingplant.Scope of WorkDemolition, removal and disposal:• Existing hot water boilers.• Boiler breaching as requiredFurnish and install the following:© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.52

HVAC SystemsRTU ReplacementsFIM SummaryMany times rooftop units (RTUs) contain a cooling section with either a gas-fired furnace or hotwater coils for heating. Because the units are located outside, the expected life is limited to 15years and the existing units have well exceeded this life expectancy. Replacement of theexisting units with high-efficiency units containing high-efficiency condensing units and furnacesections will provide significant energy and operational savings for the District. The replacementof aging condensing units will also remove harmful refrigerants which are being phased out ofproduction, allowing the District to achieve greater environmental responsibility. New units alsocome with packaged building automation controls and variable frequency drives, whereapplicable, which will reduce energy consumption even further.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThe Carrier RTUs located at the High School have reached the end of their rated life and shouldbe replaced. The units recommended for replacement are: RTUs 16, 17, 18, 3A, 4, 5A, 6A, 7A,12A, 14, 5, 6, 10, 11, 13 & 15, which serve the Media Center and several classroom areas.These units will be replaced in kind with the same size single-zone York or equivalent unit. Thenewer units will feature a more efficient cooling section, supply fan, and better unit constructionwhich will provide energy savings. The units will also be tied into the building automation systemto ensure they operate as efficiently as possible and only when needed.Scope of Work• Demolition, removal and disposal of existing rooftop units• Furnish and install the following:o YORK or equivalent high efficiency packaged unitso Reconnect all applicable pipingo Install new roof curbs as needed for new equipmento Electrical power and control wiring to new unit(s)o Coordinate with new DDC controls• Provide new unit start-up and commissioning© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.55

Convert RTU from Electric to Gas HeatingFIM SummaryCertain types of equipment can use electricity, natural gas or oil. These types of equipmenttypically include boilers, kitchen equipment, laundry equipment, domestic hot water heaters, andair handling equipment. The energy usage is mainly for heating purposes.The energy cost for various energy sources will vary per the location, availability, operating timeand other local situations. Normally, electrical energy is more costly than fuel oil, which is oftenmore costly than natural gas. Therefore, it is very important to use the right fuel at theappropriate time so that operating costs will be minimized. Constantly evaluate the economicsof fuel conversion by reviewing the available sources of energy.Johnson Controls will convert existing systems to use more energy efficient fuels as a means toreduce operating costs and extend the useful life of the equipment. By shifting to more costefficient, environmentally friendly fuels, we can reduce the total amount of energy used and thetotal cost of energy. There may also be a reduction in the amount of corrective maintenancecosts.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThe AAON unit serving the guidance office at the High School contains a DX coil for cooling andan electric coil for heating. Although the electric coil will sufficiently heat the air for the space, itis a very expensive method of heating when compared to a gas-fired furnace. Since gas isalready available to the other rooftop units at the High School, additional gas piping will be runto the AAON unit so that the unit may be retrofitted with a gas heater section in place of theelectric coil. Retrofitting the unit will be a much more cost effective solution than replacing theunit and is recommended in this case due to the relatively young age of the equipment.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.57

There may also be a reduction in the amount of corrective maintenancecosts.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThe locker rooms in the High School contain two ceiling mounted unit ventilators which provideheating and recirculation air to the Boys and Girls locker room spaces. Currently, only one of thefour total units is working and none of the units provides fresh air to the locker room spaces.These units should be replaced in order to provide working units to the areas. Replacementunits will provide fresh air to the locker room spaces as required by current building codes. Theadditional outside air and functioning units will cause the energy consumption of the locker roomspaces to increase.In order to most cost effectively provide ventilation and fresh air to replace the four locker roomunit ventilators, each locker room will have a fresh air unit installed near the exterior wall whichwill be sized for the outside air requirement of the entire locker room space. The second unitventilator will be installed on the interior side of the locker room and provide air circulation andadditional heating capacity.Scope of Work• Remove and dispose of existing unit ventilators located near exterior walls of the lockerrooms.• Provide new Reznor, or equal, gas-fired rooftop units to replace existing unit ventilators.The new rooftop units will be located as near as possible to the locker room entrance.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.59

Savings MethodologyeQUEST was used to determine the energy effects of adding the rooftop unit to condition theBoys side of the gym.Maintenance RequirementsPreventative maintenance procedures should be followed based on the manufacturer’srecommendations.BenefitsImproved comfort in the gym areaVAV ConversionFIM SummaryJohnson Controls will install variable air volume (VAV) technology in existing air handling units(AHUs) so that the building automation system (BAS) can adjust supply air needs to spaceneeds. The VAV system helps tailor energy usage to actual requirements and results in reducedenergy costs while maintaining comfort standards.As the name implies, the temperature of the space is controlled by varying the amount of airfrom the supply-air distribution system with a VAV system. This is accomplished by a spacethermostat positioning the dampers in a VAV box to match the supply air to the space needs.Normally the system is designed for the maximum demand (worst condition) but due to variousreasons we always operate the system at various loads. Therefore the supply air requirementalso varies accordingly. The VAV system reduces reheat and cooling energy and fan energy. Bysupplying the right amount of air not only is the load on the main heating and cooling systemreduced, but a static pressure sensor installed in the duct system reduces the fan speedresulting in savings in fan energy.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThree rooftop units, RTUs 10, 11, and 12, serve the media center and surrounding classrooms.Originally, these classrooms were open to the media center and did not have enclosing walls.As the school was renovated these classrooms were separated from the media center but theHVAC system was not reconfigured resulting in three single-zone units serving multiple zones.As a result, the classrooms experience wide ranges in temperature and cause significantoccupant discomfort.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.62

This measure will replace the rooftop units with new, high-efficiency units equipped with highefficiencycondensing units and VFDs in order to effectively vary the supply fan speed. Asignificant upgrade to the building automation system will also be included in order to control theVAV boxes which will be installed to replace the terminal units (diffusers) in each area. Ratherthan modify the entire ductwork system from these three units, the diffusers will be replaced withterminal unit VAV boxes. This is the most cost effective way to vary the air flow to these spaces.By providing a variable air volume (VAV) system for these three units, the occupant comfort inthe classrooms should be greatly improved.Scope of Work• Supply air diffusers from RTUs 10, 11, and 12 will be replaced with VAV terminal units• Electrical power and control wiring to new VAV boxes• Coordinate with new DDC controls• Provide new unit start-up and commissioning• Provide training and maintenance procedures for District staffSavings MethodologyThe VAV system was modeled using the eQUEST model for the High School. Complete detailsof the eQUEST model can be found in the Savings Calculation Appendix of this report.Maintenance RequirementsThe new rooftop unit will reduce the amount of repair work as compared to the existing unit. TheVAV boxes will need to be included in preventative maintenance procedures.Benefits• Natural gas savings• Improved occupant comfortExhaust Fan ReplacementFIM SummaryExhaust fans throughout the buildings are often located in hard to reach places and thereforeare not always maintained as directed by the manufacturer. The exhaust fans play a vital role incontrolling the indoor environment; properly functioning exhaust fans help to remove smells andodors as well as humidity and indoor air pollutants from the conditioned air. By replacing theexisting exhaust fans with new fans and motors, energy savings will be achieved as well asmaintaining a pleasant indoor environment. The overall HVAC system, which includes theexhaust fans, will operate more efficiently and maintenance of the equipment should be reduceddue to newer equipment in place.Facilities Recommended for this Measure• Spotswood High School© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.63

• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeNumerous exhaust fans that were installed during the original construction of each section arelocated throughout the school. Over the years these fans have come into disrepair and are nolonger functioning as intended. The most noticeable areas affected by the improper exhaustfans are the gyms in the High School and Middle School. Replacing the exhaust fans in thegyms will significantly improve the indoor comfort of the gyms. During the (ESP) it wasdetermined that the relative cost to replace the entire exhaust fan compared to replacing onlythe motor was negligible which is why the exhaust fans have been considered. The new fanswill implement the highest efficiency motors possible and be connected to the district-widebuilding automation system for improved control.Scope of WorkEach exhaust fans identified for replacement will be removed and replaced with a new exhaustfan. The new exhaust fan will include a high efficiency motor and will be incorporated into thedistrict-wide building automation system. Typical scope of work for each fan will include:• Demolition and disposal of existing exhaust fan• Provide and install a new exhaust fan to include:o Exhaust fan frameo High efficiency motor• Coordination with building automation system• Reconnect any necessary ductwork and complete any necessary ductwork modifications• Reconnect power wiring to the unit• Necessary roof flashing to accept new fanSavings MethodologySavings are attributed to the use of more efficient motors for the exhaust fans. There are nosavings attributed to a reduction in run hours of the fans. In most cases the savings werecalculated using Excel to include the difference in pre- and post- motor efficiencies, motor sizes,and run hours.

Building AutomationBuilding Automation Controls Upgrades – Central Plant, Primary AHUs, HVACSystem CommissioningFIM SummaryThe central plant of each building consists of all heating and cooling equipment and associatedpumps and typically represents the largest energy consumption used in the course ofconditioning the building. Therefore, the central plant has the greatest potential for energysavings through upgraded building automation controls. Older pneumatic controls systems oftenhave issues because they are maintenance intensive. Building personnel must ensure the airstays clean and dry, calibrate the controls and gauges regularly, and ensure that controlsstrategies are being implemented correctly. Often times, pneumatic systems are not functioningproperly which results in increased energy consumption and occupant complaints. Providingnew direct digital controls (DDC) to the central plant equipment will reduce the energyconsumption of the entire building as well as ease the burden on maintenance personnel.The primary air handlers represent the second largest energy consumer in the buildings’ heatingand cooling equipment. Pneumatic controls on the primary air handler units do not easily allowfor some of the advanced energy conservation strategies that are possible with new DDCcontrols and require maintenance personnel to maintain the pneumatic system. Significantenergy savings at the air handlers and tighter control over supply air temperature may beachieved by replacing the older pneumatic air handler controls which will result in increasedoccupant comfort.In situations where DDC controls have previously been installed, it is important to implement are-commissioning strategy in order to ensure that all applicable conservation measures havebeen activated for the central plant. The constant change in technology is another reason torevisit any existing building controls systems in order to fully take advantage of the energyconservation capabilities of the building automation system.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeAt the High School, there used to be a Schneider Electric BAS system with On/Off control ofeach of the AHUs and current supply air temperature and return air temperature were displayedfor many of the units.

working condition which results in confusion and makes the entire system unreliable.Old Schneider Electric Control System at the High SchoolThe Schneider Electric system should be completely removed and replaced with a new JohnsonControls Metasys DDC system to control the major equipment. Twenty-five rooftop units will betied into the new district-wide building automation system. The control strategies will includenight setback, demand control ventilation, economizer control, and VFDs where applicable. Insome instances, new rooftop units are recommended for installation. The new units will includefactory mounted controls to reduce the installation cost of the measure and provide the greatestbenefit to Spotswood Schools.Memorial Middle School has three sections: the original building is located in the middle of twosections – the Cafetorium addition and the Classroom addition, which were added as part of thesame renovation. The old section has approximately 12 unit ventilators with hot water heatingand DX cooling that are controlled by an older Johnson Controls’ electronic time clock for nightsetback control. The unit ventilators have hot water heating, which is provided by a single agingboiler. This boiler is to be replaced, most likely with two new Aerco boilers which will have theirown controllers. Although the original section contains pneumatic actuation, it was observed thatthe air compressor does not work which results in the units not operating or operatinginefficiently. The pneumatic systems should be upgraded to DDC systems in order to bring thebuilding back to a fully operational state.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.72

Four heating and ventilating (H&V) units serve the Gymnasium and have On/off control only;there is no apparent thermostat control of these units. The gym also has two exhaust fanswhich were reported as not working, and four louvers in the wall that tie directly to the outside.The gym units will be tied into the new Metasys DDC building automation system and includetwo zone sensors to ensure proper operation. The exhaust fans will also be tied into the buildingautomation system in order to ensure that they are operating properly and to provide acomfortable environment for occupants. The outside air dampers on the gym wall will remainclosed to allow the H&V and exhaust fans to control the gym environment.The new classroom section at the middle school has Aerco boilers with the Aerco control panelto provide hot water to the section. The classrooms are served by unit ventilators and a makeupair heat recovery unit on the roof. The make-up air unit has CO 2 Reset. There are also sixpackaged, gas-fired RTUs, one of which is a VAV system serving the main office andconference rooms. Two single-zone units serve the Cafetorium addition and already have CO 2Reset. The units should be tied to the new, district-wide building automation system.Appleby Elementary School contains a Johnson Controls’ Facility Explorer control system,although it is in need of an upgrade.

The mechanical system at Appleby utilizes a ground source heat pump loop which provideswater to several loops throughout the building. The existing well loop has two pumps which arecontrolled by a VFD but does not appear to be working correctly. The second pump wasreported to never turn on even though the lead pump may be running all out.There are two types of heat pumps throughout this building; water-to-air heat pumps whichserve the spaces and water-to-water heat pumps which serve a dual-temperature loop,providing hot water and chilled water to unit ventilators, make-up air units and a roof-top unit.Although the make-up air units have controls and can be seen from a central computer, theindividual heat pumps and unit ventilators are not visible on the building automation system. Incertain areas of the building, classrooms have both a water-to-air heat pump controlled by alocal thermostat, and outside air provided solely by a McQuay unit ventilator (on the dual-temploop) with the fan controlled by a manual control knob (with low/medium/high settings). In theserooms, we suspect that the two systems are fighting each other. The re-commissioning scopefor this building should ensure that the two units in each room work in coordination.McQuay 2-Pipe Unit Ventilator Providing Outside Air To RoomsServed By Ground-Source Heat-Pump SystemManual Control of the UV Fans© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.74

Robert Shaw thermostat controlling heat pump in a room that also has unit ventEach of the dual-temp loops are served by two small constant-speed pumps.There is a large rooftop unit that serves the multi-purpose room, it does not appear as if theeconomizer mode is working on this unit and it should be repaired.There are also four split systems located throughout Appleby School which are not workingcorrectly, because the thermostats which have been installed do not match the voltage rangerequired for communication with the units. New programmable thermostats should be installedin such a way that the split systems will function and maintain an occupied/unoccupiedschedule.Schoenly Elementary School has two sections. The oldest section contains unit ventilators withhot water heating coils and through-wall ventilation that have old pneumatic controls as well asa central boiler plant with a single boiler. There are 15 RTUs that serve the new section of thebuilding and portions of the old section. The RTUs are a mix of constant-volume and VAVsystems, and are controlled by Honeywell programmable thermostats (see below). There arealso approximately 10 unit ventilators in the new section, with hot water heating only.The intent of this measure is to provide DDC controls to the main air handling units in the newsection as well as the central plant. An option will also be provided to bring controls to the unitventilators in the rooms.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.75

Lighting System UpgradesParking Lot LightingFIM SummaryExisting high intensity discharge (HID) exterior fixtures pole-mounted throughout the district maybe replaced with newer technology LED type fixtures. The newer technology fixtures have amuch longer life and improved light quality throughout the entire life of the lamp than the existingHID lamps. The installation of photocell control will allow the light fixtures to turn on whenneeded and remain off if possible. This will provide energy savings as well as provide a safeenvironment around the exterior of the buildings.Facilities Recommended for this Measure• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeThe parking lot and roadway lighting observed around the schools utilizes older technologymetal halide and high pressure sodium lamps which should be replaced with new technologyLED parking lot lighting. By replacing the aging fixtures, electrical energy will be saved and thelight quality in these areas will be improved.Due to the electric rate structures used by JCP&L, which provides electric distribution to each ofthe facilities in the District, these lighting retrofits have an unfavorable payback period. JCP&Lbills Spotswood Schools based on the quantity of the light poles rather than the actual electricityused by these poles. Johnson Controls could aid Spotswood Schools in requesting a change inelectric structure for these poles, but most likely any change will not justify the expense ofupgrading these lights.Scope of WorkInstall the following fixtures:Building New Lighting TotalMemorial Middle SchoolNew 100-Watt LED Cobrahead With Photocell 1New 50-Watt LED Cobrahead With Photocell 4New 144-Watt LED Shoe Box With Photocell 4Appleby New 144-Watt LED Shoe Box With Photocell 4Schoenly New 144-Watt LED Shoe Box With Photocell 4© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.89

Maintenance RequirementsLighting will need to be replaced in order to provide consistent light quality throughout theexterior space. It is recommended to conduct group re-lamping on regularly scheduled intervalsin order to minimize maintenance requirements.Benefits• Electric energy savings• Improved exterior light quality• Reduction in maintenance of exterior lighting system• Improved safety around school perimeterInterior Lighting UpgradesFIM SummaryInterior lighting represents a significant amount of the electric base load throughout a building.Optimizing the interior lighting system by retrofitting any existing older technology T8 fluorescentlamps and fixtures and removing existing incandescent lamps will result in a large reduction inelectric demand and consumption charges. The new lighting system will also reduce operatingcosts due to extended lamp and ballast life and manufacturers’ warranties.Since the advent of energy efficient T8 lighting (with electronic ballast) there have been severalgenerations of improvements. Today, 25-watt and 28-watt T8 lamps offer an opportunity tolower energy consumption in areas lit by the standard 32-watt T8. The 28-watt T8 lamp hasbeen selected for this project due to its optimum light output for this application. Fixtures will beequipped with reflectors to direct the light downwards rather than all over.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeThe interior lighting throughout the District has been documented on a space by space basis toidentify all possible energy savings through a full scale lighting replacement. The full details ofthe lighting audit can be found in Appendix 1 of this report. In general, the lighting throughoutthe District will be upgraded to the latest technology T8 lamps with electronic ballasts and 25-watt T8 lamps will be used throughout the buildings.

In addition to the substantial energy savings, the new fixtures will produce morelight that is sharper and whiter than existing conditions and will dramatically enhance occupantvisibility. Also, the new lights will not exhibit the high lumen depreciation of the current metalhalide fixtures (can be up to 50% lumen depreciated on fixtures that are 3 to 5 years old).Facilities Recommended for this Measure• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeThe multi-purpose rooms in the elementary schools have not experienced a lighting upgrade insome time and are still utilizing the metal halide fixtures for lighting. These fixtures are notsuitable for school use because they cannot be re-started quickly and use an excessive amountof energy. In the case of Schoenly Elementary School, the uncertainty associated with the metalhalide lamps has resulted in the incorrect ballast type being installed on some of the lamps.Standardizing this lighting to T8 lamps will ease the maintenance burden on the District,allowing the District to purchase less expensive lamps, and provide better lighting to the space.Scope of WorkElectrician shall install the following quantity of fixtures to replace the existing lighting in thegym/ all-purpose rooms:Building New Lighting TotalAppleby New 2'x4' 3-Lamp Recessed General Troffer/NLO 18Schoenly New 2'x4' 3-Lamp Recessed General Troffer/NLO 18© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.95

Lighting ControlsDaylight HarvestingFIM SummaryJohnson Controls recommends the installation of photocell controls for interior lighting whenlarge amounts of ambient light are present in an area. Turning interior fluorescent lights offduring the day when natural lighting is available has proven to produce a more pleasantenvironment and increase the productivity of occupants. Turning the lights off based on daylightpresent and recommended light levels for the area will result in electrical energy savings as wellas prolong the life of the lamp due to fewer annual operating hours.Facilities Recommended for this Measure• Appleby Elementary SchoolScope NarrativeThe media center at Appleby School currently uses metal halide lamps which prohibit theimplementation of daylight harvesting because of the excessive time it takes the lights to turnon. With the replacement of the lights with new fluorescent fixtures, the school can takeadvantage of the large amount of natural light entering the space and shut off the lights basedon a daylight sensor. This will provide a more pleasant environment in the media center andreduce electrical consumption throughout the day. Combining this measure with an occupancysensor will increase the performance of the system resulting in even greater electrical savings.Scope of WorkThe following spaces will be controlled with a daylight sensor and occupancy sensor:Appleby Elementary School – Media CenterSavings MethodologyIn general, the following methodology was used to calculate savings from daylight harvesting.Each of the savings listed below was calculated for all four seasons (summer, winter, spring,and fall).Seasonal Dimming Hours (SDH) = Actual Daylight Hours x % clear skies% Daylight Savings = (Baseline Daily Hours – SDH)/ Baseline DailyPost Daylight Annual Hours (PDAH) =HoursBaseline Annual Hours x % Daylight SavingsElectric kWh Savings = Space lighting kW x (Baseline Annual Hours –PDAH)© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.99

Maintenance RequirementsOccasionally the daylight sensor should be checked to ensure proper operation and calibration.Benefits• Electrical energy savings• Operational savings based on reduced run time of the lamps.Lighting Occupancy ControlsFIM SummaryOccupancy sensors detect the presence or absence of people and turnlights on and off accordingly. Used properly, occupancy sensors can bea cost-effective tool for reducing the operating time and output oflighting systems, cutting energy consumption and—usually to a lesserextent—peak demand. They may reduce lighting energy consumptionby 50 percent or more in some circumstances, but the savings could bemuch smaller, so it's important to carefully consider a wide variety ofissues before installing an occupancy sensor in any specific location.Occupancy sensors are used most effectively in spaces that are oftenunoccupied, including classrooms, offices, warehouses, storerooms,restrooms, loading docks, corridors, stairwells, office lounges, andWall Mounted Sensorconference rooms. Open-plan office spaces, where one or more peoplemay be moving in and out throughout the course of the workday, are not good candidates forthis technology. Occupancy sensors can also be used to meet codes and standards—includingASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers)Standard 90.1—which increasingly require some form of automatic lighting control for newconstruction and renovations.Wall-mounted sensors are best for smaller rooms such as offices,restrooms, and equipment rooms (such as printer or copier rooms) wherepeople are only likely to be present for a short time after they walk by thesensor. In an open-plan office or where the lighting load is higher, thesensor is mounted on the ceiling.Ceiling Mounted SensorFacilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary School© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.100

Scope NarrativeCurrently, approximately 25% of the spaces utilize some form of occupancy control to switch thelights on and off. Johnson Controls typically designs an occupancy sensor strategy to controlabout 80% of the connected load which will significantly increase the amount of spacescontrolled throughout the District. As a result of the in-depth analysis of the lighting system atSpotswood Schools, Johnson Controls has increased the controlled space quantity from 25% toover 75% which will result in significant energy savings.In order to ensure the spaces recommended for occupancy control are applicable, JohnsonControls has placed lighting and occupancy data loggers throughout the space to accuratelycalculate the reduction in hours by installing the occupancy sensors. On average, spacesrecommended to have an occupancy sensor installed should experience a reduction of about45% of lighting burn hours after the retrofit.Scope of WorkThe following occupancy sensors will be installed throughout the District:Building New Lighting Controls Strategy TotalAppleby Daylight Dimming & Occupancy Control 1Occupancy Control 79Memorial Occupancy Control 58Schoenly Occupancy Control 30Spotswood Manual Dimming 4Occupancy Control 170Savings MethodologyIn general, savings calculations for lighting retrofits are calculated using the followingmethodology:Savings Calculation MethodBaseline EnergyUsage (kWh/yr)Post‐ Retrofit EnergyUsage (kWh/yr)==Existing Fixture Watts x Baseline Operating Hours/yr x 1kW/1000 WattsExisting Fixture Watts x Occupancy Hours/yr x 1 kW/1000WattsEnergy Savings(kWh/yr)= Baseline Energy Usage – Post‐Retrofit Energy Usage© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.101

Motor MeasuresMotor ReplacementFIM SummaryHigh-efficiency motors are constructed with better bearings and windings to reduce frictionaland electrical losses. Operating efficiencies are typically 3-10% higher with high-efficiencymotors compared to standard motors. Throughout the school district, any electric motor withefficiency lower than 90%, a capacity of at least 10 hp, and an annual runtime of at least 5,000hours will be replaced with a new high-efficiency (at least 91.7% efficiency) electric motor. ThisFIM will reduce the power input of all major electric motors and increase the lifetime of thosemotors without adding additional maintenance requirements.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle SchoolScope NarrativeThe exhaust fans at the schools are aging and contain failed motors which need to beupgraded.

Vending MiserFIM SummaryAll vending machines at Spotswood Public Schools were observed to run at full power, evenwhile the surrounding spaces were unoccupied. This causes energy waste as the machines useelectricity when not actually needed.To help mitigate this issue, Johnson Controls will install VendingMiser® occupancy-based,vending machine controls. The VendingMiser reduces energy consumption by an average of54% for cold drink machines and 64% for snack machines, while maintaining the temperature ofthe vended product. Using a passive infrared (PIR) sensor, VendingMiser powers down avending machine when the area surrounding it is unoccupied. It also monitors the room’stemperature and automatically re-powers the vending machine at one- to three-hour intervals,independent of occupancy, to ensure that the vended product stays cold.To eliminate compressor short cycling, the vending machine will never be powered down whilethe compressor is running.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeThe VendingMiser® is an occupancy-based energy control product. It typically results in a 46%reduction in energy consumption, while maintaining the temperature of the vended product.VendingMiser uses a Passive Infrared Sensor to:• Power down the machine when the surrounding area is unoccupied• Monitor the room's temperature• Repower the cooling system at one to three hour intervals, independent of sales• Ensure that the vended product remains coldEnergy savings result from reducing machine run time when the space is not occupied andmaintaining cold temperatures as needed by cycling the compressor.VendingMiser® vending machine controls will be installed on each vending machine specified inthe table above. Installation of the controls will require coordination with operations and securitystaff since it involves installing a device on each piece of equipment. Installation scheduling isrequired to minimize the impact on day-to-day operations and not compromise security levels.No building-wide utility interruptions are anticipated. The new device will integrate with theexisting vending machines. The VendingMiser® vending machine controls have a 1-yearwarranty.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.106

Kitchen Equipment and SystemsKitchen Hood ControlsFIM SummaryKitchen fume hoods are usually operated from the time the first kitchen employee enters thekitchen to the time the last kitchen employee leaves the kitchen. Operating the fume hoods atfull power all the time wastes electrical fan energy and the fume hood also draws conditioned airout of the space causing the heating and cooling systems to over work. There is significantenergy to be saved by controlling the fume hood fans based on the cooking load directly below.The fan will be modulated based on monitoring of the exhaust air temperature and smoke loadinside the hood.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThe Melink Intelli-Hood® Operator will automatically control the speed of the exhaust and makeupfans listed above to ensure optimal hood performance.

Electrical SystemsDemand ResponseFIM SummaryRecently, most Demand Response participation has been limited to summer emergencyprograms, also known as Capacity Programs or Interruptible Load for Reliability (ILR). Suchprograms are characterized by a demand for participants to respond via an inflexible commandand control approach. By offering a variety of programs to capitalize on the financial andenvironmental benefits of Demand Response, Johnson Controls enables socially-responsibleenergy users like Spotswood Schools to contribute to a more reliable power grid. The variousdemand response programs available to customers are described in more detail below:Description of EnergyConnect Demand Response ServicesEventConnect Capacity ILR ProgramEnergyConnect’s ILR Capacity program is branded as EventConnect and customers are paidto be on standby to drop a portion of their load in response to a PJM-initiated emergency event.Although there is a maximum of ten potential events per year, historically there are rarely morethan one or two events actually called. To verify program integrity, there is a mandatory onehour test to validate all committed load drops are indeed a reliable resource in the event of anactual grid emergency.FlexConnect voluntary Economic DR programEnergyConnect is unique in its industry leadership and on-going commitment to voluntary priceresponsive load management. EnergyConnect’s vision has long focused on Economic DemandResponse which encourages frequent (and voluntary) customer involvement. In 2008 and 2009over 50% of all PJM’s Economic DR transactions were settled with the EnergyConnect.Participation is very easy and intuitive: from a simple, web-based scheduling screen, it takesless than five minutes per day to determine the level of voluntary participation, based upon yourassessment of its expected operational needs compared to the next day’s price opportunity.EnergyConnect also monitors the market, sending e-mail alerts to customers on opportunitiesthat meet pre-determined target prices. If the opportunity looks good, users schedule aneconomic curtailment in as few as ten minutes prior to the next hour. If it does not, they simplyignore the message and go about their daily business.FlexConnect participation requires that a customer buy electricity on a fixed rate. If SpotswoodSchools purchases their electricity supply on a Block and Index, that effectively preventseconomic participation since the indexed portion is equivalent to Locational Marginal Pricing© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.115

(LMP). If the pending FERC Notice of Public Rulemaking is approved, it is expected that B&Icustomers will earn the full LMP for a set number of hours, to be defined by FERC.As a block and index purchaser of electricity, managing consumption above the fixed block ratehas important consequences to a budget. With the exposure to year round wholesale ratevolatility, it is now important to remain vigilant of hourly prices and to know your load at all times.The visibility provided by GridConnect into both the day-ahead and real-time LMPs providesvaluable information that allows you to reign in your usage, reduce your capacity charges, andlevel your usage patterns (load factor) for superior future supply agreements. In short,GridConnect helps reduce your electricity bill.ReadyConnect Synchronous ReserveCustomers are paid to be on standby to drop a portion of their load with a 10 minute notice, forup to 30 minutes. There are typically 1 – 3 events per month that average around 10 minutes induration. Standby payments are based on market rates and can range from $20,000 - $50,000per MW for the year depending on availability of load drop and market demands. Largebuildings and office campuses with advanced building automation systems can lend themselveswell to these programs since the event duration is very short. Significant load can be reducedwithout a noticeable impact to building occupants.In the PJM Emergency Capacity programs, EnergyConnect recommends and supports ourcustomer’s efforts to execute demand response trial events to verify that curtailment proceduresare followed appropriately and that mutually agreed upon kW load reductions are achieved.Post event meter data is analyzed and reviewed with your facilities personnel to verifysuccessful curtailment efforts or address any unexpected shortfalls in reduction. TheGridConnect platform puts all this data at your fingertips.After a customer is signed into our program, they are assigned an account manager(s) to helpthem through the initial process and program familiarization through formal training. Economicand Emergency programs, software and bidding strategies and financial screens are reviewedin order to help each site to direct access to all revenue earned by participating in the programs.The account manager monitors load response performance and works with our customers tooptimize participation and earnings. They will engage with our energy specialists and engineersfor help with ongoing demand response projects to enable higher participation. Customers alsohave access to our settlement analysts in our customer operations center located in Campbell,CA. Settlement analysts are available by phone or e-mail during all business hours.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary School© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.116

Scope NarrativeThe peak load contribution (PLC) numbers were evaluated for the buildings at SpotswoodSchools in order to determine the potential for revenue generation through participation in oneor all of the demand response programs available. The PLC numbers for the four buildings total708.67 kW which represents the maximum load that could be included in the EventConnectCapacity program. During the analysis, Johnson Controls evaluated the equipment schedulesand run times that would need to be implemented in order to shed this size load and it wasdetermined that it would cause unfavorable conditions in the buildings. A load reduction of thismagnitude would require most of the buildings to be turned off which is unreasonable due to theusage during the summer months. Alternately, the generator at the High School could be usedto shed load during a demand response event. The size of the generator, 100 kW, is too smallto generate economic benefits for Spotswood Schools, the cost to install the meteringequipment and software would far outweigh the financial benefits of program participation.Demand response is not recommended for this District.Scope of WorkDemand Response participation is not recommended for Spotswood Public Schools.Savings MethodologyThere are no energy savings for this measure. Revenue generation is calculated based onprevious experience in the demand response market utilizing the District’s ability to shed load.The Peak Load Contributing (PLC) numbers are used gauge the capacity for load shedding.Maintenance RequirementsNot applicableBenefits• Reduced maintenance efforts to participate in demand response events• Ability to participate more actively in demand response programs• Revenue generation for the school districtReplace Transfer Switch on GeneratorFIM SummaryThe generator equipment at Spotswood High School has a transfer switch in need of repair.This measure addresses this maintenance issue.Facilities Recommended for this Measure• Spotswood High School© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.117

Building EnvelopeInfiltration ReductionFIM SummaryInfiltration drives energy costs higher by allowing unconditioned outside air to enter the building,thus adding to the building load and causing additional unnecessary heating and cooling loads.Each building within the scope was surveyed in order to identify potential improvements foroutside air infiltration reduction. The main observations are listed below:• Air pathways through exterior doors, windows and roof/wall intersections allow air toinfiltrate the buildings directly.• The building chases (electrical, mechanical, etc.) allow air to freely flow through parts ofthe structure.• Some soffit areas are open to the exterior.These deficiencies mostly reflect the skin of the buildings which have either existed sinceoriginal construction of the building, were added during some retrofit periods, or were caused bydeterioration.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeOur initial investigation was to identify energy loss in the facility. The buildings were generally ingood physical condition. Constructed of brick, the exterior is mostly maintenance free.Penetrations in exterior walls for piping, etc., are few. Windows are sealed well.Window sealant was found to be mostly in good condition throughout the facilities. Doorsystems were found to be the largest areas of air infiltration district-wide. Almost every entrancedouble door needed one of the following: weather stripping, sweeps, or the closure or strikeplate adjusted. Most entrance doors had a set of vestibule doors just feet away to help stopunconditioned air flow. However, in multiple instances vestibule doors were left open, probablydue to the fact the heaters in the vestibule areas were running non-stop. Vestibule doors shouldstay shut and many doors would benefit from adding sweeps, weather stripping, or centerbands. The doors should be readjusted and weather stripped properly to stop airflow.Penetrations through fire-rated assemblies are required by code to be fire-stopped using a ULtested assembly. It is quite common for contractors doing retrofit work and installing computerequipment to leave this task up to building maintenance people.

issues that should be addressed. Typically these occur in kitchens, equipment rooms andstorage areas.Building DescriptionsAppleby Elementary SchoolAppleby Elementary School is constructed of concrete masonry and brick exterior. Windowshave been recently replaced with vinyl clad wood with blinds between the double panes ofglass. Most windows were found to be unlatched, causing energy loss at the sill. This iscommon in this type of window, because often people forget to latch the windows when closingthem, or they are too difficult to properly latch/lock. Once latched, they seal well. Penetrations inexterior walls for piping, etc., are few , however those need to be sealed. Maintenance has donea good job of keeping up with weatherization issues. Many of the steel doors have beenreplaced with fiberglass door systems. Where these doors have been replaced, in rare cases,only the sweeps need replacing. Gaps between the cabinets of the unit heaters and the exteriorwall where the heaters draw in outside air need to be sealed to the wall to prevent unnecessaryair infiltration.Fan Coil Units energy loss through gaps at wallGaps between Fan Coil Units and wall© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.124

Spotswood High SchoolBuilt in 1976 of concrete masonry block with brick masonry finish, Spotswood High School is inrelatively good condition. Most of the areas of infiltration occur at doors where thresholds arecrushed and sweeps and astragal seals are damaged or missing. Some doors needadjustments so they close better. Windows are operable metal frame and are tight fitting.Weather stripping has been installed on overhead doors in the maintenance garage and storagearea, but the method used for fastening creates an opening that must be sealed to make theweatherization effective. Entranceways above doors #1 and #17 have energy leakage at theintersection of the soffit and the wall. Sealing the crack may not stop the energy loss. Additionalinvestigation to find the source of the losses may be warranted, should this project be approved.Heat loss around door frameDoor #16 replace weather strippingHeat loss around door #24 in band room Band room door© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.127

Memorial Middle SchoolMemorial Middle School, constructed in 1967 and added to in 2004 is constructed of concretemasonry block with brick finish. Windows are metal frame with shades in good condition.Windows close tightly and are latched well. Doors are in need of weather stripping andthresholds are crushed from years of use. Energy savings may be realized by replacing thethresholds and installing new door sweeps. Vestibule doors were left open, and should remainclosed as an additional barrier to energy loss. The mechanical room shows evidence of energyloss at the head of wall, and this condition may carry throughout the 2004 addition. Furtherinvestigation is necessary to confirm the extent of this condition. Based on a conversation withthe engineer we carried a ¼ inch crack in our calculations for this condition. Valves andequipment are left un-insulated and if still used represent energy loss. We noticed lights neardoors #8 and #15 that were filled with water. We observed several open windows indicating theoccupants were uncomfortable, or they forgot to close them. In the mechanical server roomthere were several penetrations through the firewall that were not properly fire-stopped.Open vestibule doors and crushed threshold Un-insulated valves and equipment© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.129

Energy loss at wall intersection Failed sealant vertical control jointFailed sealant vertical control joint Damaged soffitScope of WorkThis Facility Improvement Measure includes locating and sealing gaps in the building envelopesystem to reduce infiltration. Gaps will be identified by visual inspection, camera, and measuringair flow. As indicated in the summary table of the scope of work:• Doors will receive new weather-stripping, sealant and door sweeps• Exterior and interior penetrations will be sealed• Roof-wall seams will be resealed with complete vapor barrier improvements• Piping and electrical penetrations will be insulated and sealed.The proposed weather-stripping consists of an extruded aluminum carrier with a clad forminsert. It will be installed using a compression fit that allows flexibility should minimal shifting ofthe door occur. The weather-stripping will be applied at the sides and across the top of the© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.131

doorframe. A sweep will be installed on the inside bottom of the door. All door weather-strippingwill be sealed after installation using a paintable, silicon acrylic sealant. Latches will be checkedto ensure they close and lock properly and closures will be adjusted. Doors will also be checkedfor damage, such as old screw holes and penetrations. When found, penetrations will be sealedto minimize air infiltration and exfiltration.Notes:1. After the weather-stripping is installed, the doors will be aligned, balanced and tested forproper operation. The weather-stripping/sweep should be inspected annually.Components can be replaced as needed.2. Door weather-stripping material is referred to as DF, which references DF Commercial/Industrial weather-stripping. The reference to DS is for the door sweep material, which isalso a Commercial/Industrial product. Center bands are elongated sweeps with a centerfin-seal material. All door weather stripping material has a mill finish.Savings MethodologyThe energy savings derived from this measure are a result of the heating and cooling systems(chillers and boilers) not having to work as hard to achieve the desired environmentalconditions. The amount of savings is dependent on the existing building conditions and theamount of air leakage under the current operating conditions.Energy savings are based on the ASHRAE crack method calculations. If the process revealsany variation in the as-built conditions, then savings will be adjusted accordingly. Determinationof air current air leakage rates is based on many factors, including:• Linear feet of cracks• Square feet of openings• Stack coefficient• Shield class• Average wind speed• Heating or cooling set point• Average seasonal ambient temperaturesSavings due to infiltration reduction:The following equation is based on the ASHRAE crack method:Heat loss per hour: q = 1.08 x Q x ΔTWhere Q represents the airflow in cubic feet per minute (CFM) and is calculated in the following manner:Q Acrack( C T C Vsw2© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.132

In this equation, A crack represents the crack area in square inches to be reduced. The other values in theequation are standard for these buildings and are based upon shelter class, height, and local wind speed.• Cw = wind coefficient = 0.0104 average• V = wind speed = 8.8 average mph• Cs = stack coefficient = 0,0299 (two-story typical)• ΔT = temperature difference = Tout – TinΔT is calculated by subtracting the average outdoor air temperature per hour from the indoortemperature, using 24 data points per month to accurately account for weather variances, andsubsequently calculating airflow and heat loss for each set of data. Therefore, 288 data points are used,and Δt is the number of hours each data point represents. The total heat loss is calculated as follows:288q Ax 1.081crackCs2TTC V TTtoutinwoutinMaintenance RequirementsAfter the building envelopes have been improved, operations and maintenance should bereduced, due to improved space conditions and lower humidity during the cooling season. Themaintenance staff should maintain the newly installed equipment per manufacturers’recommendations. The manufacturer specification sheets will be provided for exactmaintenance requirements.Benefits• Electrical energy savings• Fuel energy savings• Increased thermal comfortRoof ReplacementFIM SummaryThe roof a building can cause energy waste throughout the year. A lack of insulation betweenthe roof structure and the conditioned space often results in excess heat gain as a result of thesun beating on the roof throughout the year, and conduction during the summer as well as heatloss during the winter months. Another issue that may arise with roofs is leaking through cracksand weather damage. Replacement of the roof with a new high-efficiency roofing system willreduce the energy consumption through increased insulation values, as well as repair any leaksor holes in the structure. Occupant comfort will be improved due to a reduction in heating loadfrom the roof and maintenance will be easier because many existing problems with the structurewill be repaired.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.133

Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Schoenly Elementary SchoolScope NarrativeThe original section of Memorial Middle and Schoenly Elementary Schools contain older roofingsystems which have been identified for replacement. The majority of the High School roof wasalso identified as needing replacement. A roof study was completed for the District whichidentified several locations on the roofs which were in need of immediate repair. Rather thancomplete patches in certain spots, this measure will replace whole sections of the roof. Theoriginal section of the both the Middle School and Schoenly Elementary School roofs will bereplaced with a new roofing system. During the design phase it will be confirmed if the roofsystem will consist of a built-up system or EPDM roofing.Original Section of the Middle School Roof Displaying Several Areas of Wear© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.134

• Operational savings based on repairing any roof leaks or issuesWindow Wall ReplacementFIM SummaryOlder, single-pane windows do not provide insulation from the outside air that newer, doublepanewindows can provide. In addition, the clear glass allows the sun to generate excessiveheat in the conditioned spaces which results in occupant discomfort. The installation of new,energy efficient, windows will reduce the amount of heat lost to the exterior through betterinsulation. The installation of new windows will also ensure proper sealing around the windowsreducing the amount of air leaking into the building. All of these benefits will save energy andincrease occupant comfort.Facilities Recommended for this MeasureSpotswood High SchoolScope NarrativeThe windows at the High School are original to the building and are in need of replacement. Theexisting sections of wall contain single-pane clear windows which offer little thermal insulationand they are surrounded by blue thermal panels with a limited R-value. On mild days during thesite audits, the interior of the walls were noticeably cold to the touch resulting in veryuncomfortable classrooms and offices. In addition, there are electric sill heaters to combat thecold from the wall panels which consume electric energy during the fall, winter, and springmonths.Wall of windows – front of building© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.136

As part of the retrofit, the walls and windows will be completely removed and rebuilt to includedouble-pane glass and a new wall section with significantly more insulation. As a result of theimprovements in the insulation of the wall, the electric sill heaters will no longer be needed,which will result in significant electrical energy savings. An added benefit to the project will bethe improved comfort for the occupants as well as a clearly visible improvement to the schoolbuilding.Scope of Work• Remove and dispose of existing windows, sills, insulated panels, associated woodblocking, and trim.• Existing lintels will be cleaned and prepared for re-finishing.• Existing lintels are to receive a high performance paint coating• New, architectural grade, thermally broken, pre-finished aluminum double-pane windowsare to be installed• Construct new infill walls to consist of masonry veneer and fill with 6-inch batt insulation• Provide new solid polymer sills at each new window• The interior electric sill baseboard heat will be disconnected• The interior electric baseboard heat will be removed and disposed of as neededSavings MethodologyThe savings for the window wall replacement were calculated by increasing the R-value of thewalls in the eQUEST model and replacing the single-pane windows with double-pane windowswithin the model. The details of the eQUEST models are included later in this report.Maintenance RequirementsNo added maintenance of the windows or walls will be necessary from what the District isalready doing.Benefits• Electrical energy savings• Natural gas energy savings• Improved occupant comfort• Improved aesthetics of the building© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.137

Water System and ControlsElectric Hot Water Heater to Gas ConversionFIM SummaryDue to the high cost of electricity compared to natural gas, heating domestic hot waterelectrically becomes very expensive. These units should be replaced with natural gas-fireddomestic hot water heaters in order to achieve utility cost savings.Facilities Recommended for this Measure• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeSeveral smaller electric hot water heaters arelocated in the three schools listed above. The costto generate hot water using electricity is much morecostly than generating hot water with natural gas.The installation of similarly sized, natural gas firedheaters will produce the same amount of hot waterfor a significantly lower price. This measure willinclude all applicable gas piping and start up for afully functioning system. Newer hot water heaterswill also reduce any maintenance or capital costexpenses due to replacement of the aging heatersresulting in fewer burdens for the maintenanceteam.Scope of WorkProvide labor, materials, tools, and supervision to perform the following:• Remove existing electric domestic water heater• Pipe new natural gas lines to tie into existing lines• Start up and 1 year warranty service• Water heaters to match existing size and BTUs• Insulation of piping• New electric service to burner• Training for personnelElectric Water Heater at Schoenly School© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.139

Savings MethodologyThe savings for the electric to gas hot water heater conversion were calculated using thefollowing methodology. The hot water consumption was compared to the overall water usage inorder to calibrate the baseline water and provide realistic savings calculations from the fuelswitch.Existing Heater:Btu Needed to Heat Water[HWB]= DHW Gallons x Specific Heat x 8.34 Conversion Constant x ΔTInput HW Btu [HW IN] = HW IN/ (Combustion Efficiency – Cycling Losses)Skin Losses (SL) = Nameplate Input Capacity x 0.5% x 8760 hrs/ yrLoop Losses (LL) = Nameplate Input Capacity x 3.0% x 1920 hrs/ yrInput Needed to RecoverLosses (Loss IN)= (SL + LL) / (Combustion Efficiency – Cycling Losses)Annual Consumption in Btu = Input HW Btu + Input Needed to Recover LossesFor electric hot water heaters the combustion efficiency is 100% and the typical cycling lossesare 1%.Proposed Heater:Btu Needed to Heat Water[HWB]= DHW Gallons x Specific Heat x 8.34 Conversion Constant x ΔTInput HW Btu [HW IN] = HW IN/ (Combustion Efficiency – Cycling Losses)Skin Losses (SL) = Nameplate Input Capacity x 0.5% x 8760 hrs/ yrLoop Losses (LL) = Nameplate Input Capacity x 3.0% x 1920 hrs/ yrInput Needed to RecoverLosses (Loss IN)= (SL + LL) / (Combustion Efficiency – Cycling Losses)Annual Consumption in Btu = Input HW Btu + Input Needed to Recover LossesThe gas-fired hot water heaters have a combustion efficiency of 85% and the typical cyclinglosses are 1%.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.140

Savings results from the difference in Annual Consumption. In the case of the fuel switch, theutility rates result in cost savings. The conversions from Btu to electric and Therms of naturalgas areas are as follows:1 Therm = 100,000 Btu1 kWh = 3,413 BtuMaintenance RequirementsMaintenance requirements will be identified by the manufacturer upon successful award of bids.Benefits• Utility cost savings• Capital improvements to heating equipmentLow Flow Plumbing Fixture ReplacementFIM SummaryWater usage at educational institutions has become a focal point of concern in recent years,due to increasing unit costs for water and sewer service. Water conservation measures areunique in that they address a portion of facility utility costs that may be overlooked whenconsidering other energy conservation measures. Reducing water consumption throughdomestic water fixture upgrades yields utility cost savings from decreased water and sewercharges. Additionally, it decreases electric and natural gas consumption, as reduced hot waterusage conserves energy required to heat the water.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeDuring the detailed analysis of the water systems throughout Spotswood Schools, JohnsonControls engineers determined that the majority of equipment has been updated with low flowtechnology. In very few cases, the original equipment was still in place, but these areas werefew and far between and a full-scale water conservation project at the site is not warranted.During the course of normal maintenance replacement of china and fixtures, the replacementequipment should be low flow technology.

The other two fields utilize on-site wells to provide water forirrigation which eliminates the need for utility water purchasing. This measure would install awell near the baseball field to supply irrigation water to the field. Any necessary pipingmodifications to the field irrigation system would be included in this measure.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.142

Additionally, water from this new well could be piped to the water well supplying the soccer field.This well was reported to be lacking in capacity and the irrigation needs could be served by anew well. The soccer field well is approximately 725 feet away from the baseball field well,which could make the cost of this interconnection very high. The schematic below details thepotential piping run from the water wells.Scope of WorkPreliminary layout of well pipingThe following scope of work is recommended for the installation of a water well to serve thebaseball field:• Install one well to provide irrigation water to the baseball field• Install necessary piping and pumping equipment to provide water to the field• Complete necessary site approvals and obtain all permits and utility approvals• Complete any necessary landscaping work to bring grounds back to initial condition• Install necessary fences and enclosures for pumping system• Tie the new water well system into existing system serving the soccer fieldso Provide necessary trenching, excavating, and piping work to connect the twosystems (approx. 725 linear feet)o Restore the grounds to their original conditionSavings MethodologySavings from this measure result from not having to purchase water from the township.Maintenance RequirementsRegular maintenance of the water well system should be conducted in order to ensure properoperation.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.143

Renewable SolutionsSolar PVFIM SummaryGeneral OperationSolar electrical energy is generated when the sun’senergy strikes a solar photovoltaic (PV) panel. A seriesof PV panels are combined in PV arrays that sendDirect Current (DC) to an inverter, which converts theelectricity to Alternating Current (AC) power. The ACpower is integrated into the building’s electrical system,thereby reducing the amount of expensive electricitythat must be purchased from the grid. Solar PVsystems can be sized to produce as much or a littlepower as is required in a given application.Net MeteringThe New Jersey Board of Public Utilities Net Metering Guidelines allows onsite Districtgeneration using solar energy sources. There are clearly defined procedures for interconnectingsolar systems with the building and the grid. With Net Metering, all the power that is producedby the solar system will either directly offset purchased power that would otherwise beconsumed in the building or, if the building is consuming less power than the solar system isproducing, the solar power will be fed to the grid, effectively running the meter backwards. Ineither case, every kilowatt that is produced by the solar system will offset purchased power atthe full retail value.Ongoing MonitoringMonitoring the performance of the PV system is necessary and easily accomplished.Performance data is accessed through the system’s inverter and revenue grade meter in orderto:• Assure that the system is operating as expected,• Immediately know if there is a requirement for any service,• Validate system performance for purposes of Solar Renewable Energy Credits (SRECs)sales• Effectively and transparently communicate to environment, economic and educationalattributes to the students, faculty and public© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.145

Economic BenefitsIn addition to the well-known and important environment benefits a solar system produces, verysignificant economic benefits make the ownership of a solar system very financially compelling.The economic benefits of owning a solar photovoltaic system are fourfold:• Reduction in the use of costly grid power• A long term risk management hedge against volatile electricity prices• Virtually free power for 15 to 20 years after the finance term has ended• Significant revenue from the sale of the Renewable Energy Certificates that the systemproducesSolar PV: The Natural ChoiceIn an increasingly competitive business climate, it is imperative to find new, innovative ways tocut costs and gain competitive advantage. As the world continues to place increasing value onresource and environmental conservation, solar power offers a unique opportunity for you togain an economic and environmental edge. The perfect time to invest in solar is now, and hereis why:Solar provides an effective hedge against fluctuating and rising electricity prices: Futureelectricity prices are increasingly difficult to predict due to volatile fuel prices and the uncertaintyaround future climate legislation. Distributed solar power offers a predictable alternative topurchasing energy from the grid and consistently delivers peak energy at prices at or below themarket rate for as long as 30 years.Solar can serve as a competitive advantage: Withfederal, state and municipal incentives, thetechnology is cost-competitive with marketelectricity rates in New Jersey. Packaged with costcuttingenergy efficiency measures, solar powercan dramatically reduce average monthly electricitycosts.It is also the right thing to do: solar power is a renewable, clean resource that produces zeroharmful pollutants or greenhouse gases that exacerbate climate change. A substitute for dirtieralternatives, such as coal, it can also reduce our nation’s dependence on insecure, foreignsources of energy. Finally, it establishes your school district as a responsible community leaderthrough local job creation and sustainable innovation.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.146

Savings MethodologyFor purposes of calculating the electricity generated by the solar PV system recommended forSpotswood School District, an analysis tool called PVsyst was used. PVsyst is an industry bestin-classsolar modeling software and uses local climate data to determine the amount of sunlightavailable for power production.PVsyst DetailsThe PVsyst calculator determines the energy production and cost savings of grid-connectedphotovoltaic (PV) energy systems throughout the world. It allows homeowners, installers,manufacturers, and researchers to easily develop estimates of the performance of hypotheticalPV installations.The calculator works by creating hour-by-hour performance simulations that provide estimatedmonthly and annual energy production in kilowatts and energy value. Users can select alocation and choose to use default values or their own system parameters for size, electric cost,array type, tilt angle, and azimuth angle. In addition, the calculator can provide hourlyperformance data for the selected location.Using typical meteorological year weather data for the selected location, the calculatordetermines the solar radiation incident of the PV array and the PV cell temperature for eachhour of the year. The DC energy for each hour is calculated from the PV system DC rating andthe incident solar radiation and then corrected for the PV cell temperature. The AC energy foreach hour is calculated by multiplying the DC energy by the overall DC-to-AC de-rate factor andadjusting for inverter efficiency as a function of load. Hourly values of AC energy are thensummed to calculate monthly and annual AC energy production.Maintenance RequirementsThe solar panels will require minimal maintenance which will be described in the manufacturer’sspecifications. After the installation of the panels, Johnson Controls will help SpotswoodSchools prepare a bid specification for maintenance services for the panels.Benefits• Electric savings• Educational Opportunity• Decreased reliance on utility electric• Revenue generation through sale of SRECs© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.151

Benefits• Project funding.• Public acknowledgement of District’s efforts toward energy responsibility.Solar Renewable Energy CertificatesFIM SummaryIn New Jersey, power suppliers (utilities) are required to include a significant percentage ofrenewably generated power in their generation portfolio in addition to natural gas, nuclear andcoal. This requirement, called the Renewable Portfolio Standard (RPS), increases year afteryear into the foreseeable future. The most efficient way for power suppliers to accomplish this isto purchase Solar Renewable Energy Certificates (SRECs) from owners of renewable energysystems such as Spotswood Schools.

Information TechnologiesPC Power ManagementFIM SummaryEnergy consumption waste within a facility attributed to personal computers (PCs) is very oftenignored. PCs are typically left on by the user even if they are not being used. Johnson Controlsproposes to reduce this wasted energy through implementing a program that automatically andcentrally manages power settings through a network based program.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeJohnson Controls proposes to install an easy-to-deploy software utility that addresses networkenergy waste and reduces operating costs without impacting PC users. The product measures,manages, and minimizes the energy consumed by the network's PC clients through onecentralized interface. It provides IT departments with a powerful approach to automate energyefficientbest practices throughout their networks, while it adds new control and flexibility totraditional PC power management.This PC energy management tool is a client-server software solution that would allow theSpotswood Public School District to measure, manage, and minimize the amount of energyconsumed by personal work computers and monitors. This software sets the powermanagement options of the networked computers on a schedule customized by IT Departmentstaff to meet the user’s needs. Installation of the server software is very straightforward. Existingsystem conditions would be verified such as connectivity to a remote database and presence ofcertain system requirements for the software.Johnson Controls will work with the District to install and rapidly deploy the software on theDistrict’s computer network. The installation plan will address server and client installation, basicadministrative configurations, logical power management profile groupings, and energyconsumption reporting.Scope of WorkJohnson Controls will quickly and efficiently install the server and its clients for the personalcomputer power management system.A total of 975 networked computers will be affected© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.159

Johnson Controls will initiate a pre-installation planning meeting to confirm any relevant networkcharacteristics and define the project’s timeline and responsibilities. The client software will bedeployed, implemented and configured on the District’s network either remotely or manually.Once installed, the Johnson Controls team will train the District’s system administrators andreporting tool users.The Johnson Controls team will help assure the District’s success through our annualmaintenance program. This provides the District with ongoing technical support, softwareupdates and upgrades, and an annual Network Energy Analysis to confirm the most effectiveuse of the system and allow for any incremental changes.Savings MethodologySavings are calculated based on the reduction in on and standby time of the networkedcomputers. An accurate account of computers and power policies was obtained by surveyingthe IT department staff to identify the types of computers and monitors throughout the district.Using the types and quantities of computers and manufacturers’ information regarding powerconsumption, a reduction in hours is used to determine the annual electric savings.Maintenance RequirementsAn annual maintenance plan and support for the software should be purchased by the District.Once the ESIP is complete, Johnson Controls will work with the District to issue bids for aservice provider.Benefits• Simple to use• Energy savings© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.160

Facility ManagementFacility Performance IndexingFIM SummaryFacility Performance Indexing (FPI) has been designed and developed by Johnson Controls toadd significant value to facility organizations, in particular the maintenance and diagnosticsassociated with major systems such as chillers, boilers, air handling units, rooftop units, andterminal devices, and all controlled equipment. It provides a practical methodology that allowsfacility owners and maintenance personnel an understanding and immediate feedback on howtheir equipment is performing and operating in an intuitive dashboard display.The ChallengeThe creative and successful application of advanced technology in the HVAC industry iscredited to numerous benefits; extending the reach and capability of an existing workforce,providing empirical evidence and performance-based results, enables targeted decision-making,drives process change through benchmark developed data, and has resulted in a reduction intask-based maintenance activities, which is realized in greater manpower capacity.A critical piece in effective facility maintenance management is the periodic assessment of thereliability, maintainability, performance, and remaining useful life of equipment. As maintenancetechnology continues to move forward, progressive facilities are beginning to embracecondition-based assessment toolsets.The condition assessment standards of the industry include predictive technologies. In the past,those technologies were primarily limited to mechanical system evaluation. Implementation of acontinuous improvement project typically starts with an initial condition assessment to establisha reference or baseline data-set for an asset. The data is then used to detect performancechanges and make decisions based on criticality and severity. The assessment provides aquantifiable definition of the inherent reliability of a critical asset, as well as a comprehensive listof deficiencies that must be resolved to ensure continued reliability, maximum useful life andlowest life cycle cost.The methods used in this type of program must include a way to obtain quantifiable data toeliminate perceptions and opinions. For example, air handling unit surveys should usediagnostic tools that accurately detect system performance and identify changes inperformance, rather than subjective reporting.Ideally, the method used would provide a continuous and quantifiable measure of relativesystem performance, and would not be limited to labor intensive and costly programs such as adedicated retro-commissioning team, which evaluates the equipment in a static fashion. Mostbuildings today include some form of building automation system that has the capability of© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.163

collecting and processing large amounts of data. Turning that data into useful systemperformance and optimization information is the challenge for present day facility managers.The SolutionFacility Performance Indexing Service is a combination performance monitoring and predictivemaintenance service that utilizes Johnson Controls METASYS system (Metasys ExtendedArchitecture and Legacy Metasys) to take a continuous snapshot of the operating parametersand conditions of facility equipment. Using an OPC data server, other systems can also beintegrated into FPI.This quantifiable, continuous condition assessment is an extremely valuable management toolthat provides facilities management with the knowledge needed to manage the life cycle andmaintenance costs of the assets effectively. When combined with an effective conditionmonitoring or predictive maintenance program, managers will have the factual data needed toachieve and sustain optimum reliability, useful asset life and best life cycle cost.Facilities Recommended for this Measure• Spotswood High School• Memorial Middle School• Appleby Elementary School• Schoenly Elementary SchoolScope NarrativeThe Facility Performance Indexing service utilizes data collected from the existing Metasys (orother) system. Continuous analysis of the controlled components determines the actual systemperformance levels compared to optimal performance. The analysis aids the facility staff andJohnson Controls in the identification and correction of system/component issues proactively,resulting in more reliable facility operations.Reasonable and effective benchmarks for acceptable relative system performance, based onyears of field tested development, have been established for each individual system component.The actual system performance is compared to these benchmarks, as well as an optimal orperfect performance level in order to identify deficiencies. As the benchmarks have beenstandardized, a true “apples to apples” comparison of relative performance can be made.Therefore, the performance index calculation results can be used to quickly identify the poorestperforming systems, which can be used to prioritize maintenance activities. Any deficiencies areeasily identified for more detailed investigation of corrective action.As an example, VAV box performance would be monitored utilizing the following parameters:• Room Temperature: Acceptable performance range from 3 degrees of setpoint• Air Flow: Acceptable performance range from 20% of cfm setpoint© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.164

• Cooling Capacity: Acceptable performance with at least 5% remaining capacitymeasured in damper position• Optimal performance would be 15% of the acceptable range (i.e. 0.45 degreesdeviation from setpoint for room temperature; for cfm, 15% of 20% of the cfm setpoint• Optimal capacity performance is realized when the controlled device (damper, valve,drive, etc.) is still capable of providing additional output if needed• A performance index of 100 indicates a system is operating at the exact parameterscalled for by the controls. An index of 0 indicates that the system is operating at anunacceptable or poor levelAs the individual parameters are evaluated, the individual component results are then used inanother calculation to summarize the components as a system. This view of the system isrepresented as the Overall system performance index. A system can be a VAV box, airhandler(s), a floor of VAVs, or even an entire facility.A time-based penalty is employed anytime one of the components of a system exhibitsunacceptable performance levels. This time-based penalty continuously degrades the Overallsystem performance level, calling further attention to a potential problem that otherwise mightbe overlooked. The time-based penalty is designed to degrade the system performance indexvalue down to zero in eight hours when any one component has unacceptable performance.Once the unacceptable performance levels are corrected to acceptable levels, the time basedpenalty or penalties are removed immediately from the Overall system’s performance level. Toensure accurate, relative performance interpretation, the penalty counters are reset at midnight(adjustable) every day.Each performance index result is rolled up to provide a picture of component, system, andfacility performance levels. This hierarchy provides the holistic evaluation of systemperformance, and helps to uncover the root cause of unacceptable performance. Rather thancontinue to make needless adjustments to a VAV box due to hot/cold calls, for example, the rootcause may be potentially identified as capacity limitations at the AHU level. The capacitylimitation could then be further evaluated, and maintenance or budget decisions made based onthe corrective action required to improve system performance.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.165

All of the calculations are done outside of the system being evaluated, in the stand-alone FPIcomputer. Data is collected, stored in an SQL database, and calculations are performed on thedata. The calculation results are written to the SQL database, and an Internet Explorer webpage is used to display the results based on the end user’s selections. The results are displayedusing a dashboard consisting of a tree type hierarchy, as well as graphs displaying historicaldata. Supporting data (actual point values) are also viewable on the dashboard tree and graphs.Real time performance levels are represented in the tree using a common sense performanceindication system for immediate visual validation. Green indicates optimal performance, yellowindicates acceptable performance, and red is indicative of a performance failure requiringinvestigation. The calculated performance level number is also displayed. Each piece ofequipment that is analyzed will display a performance color code that will update as quickly asthe system can collect the data, typically every 1-5 minutes.Screenshots of FPIFPI screenshot showing RTU-1 Performance for 24 Hours© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.166

Reporting of the user-selected system performance levels occurs in two parts, real time andhistorical. The current snapshot performance level is displayed on the left side of the FacilityPerformance Index web page. This snapshot provides the end user–the technician, mechanic,facility staff, whoever–the ability to see changes in performance as they occur and respond topotential failures before they manifest as comfort problems in the facility. As the system isdynamic, responses to changes in the building environment have a direct impact on thissnapshot performance. A change in room temperature set point, for example, would show up asa change in system performance until the temperature approaches the set point.FPI screenshot showing RTU-1 performance for 60 minutesThe performance chart is based upon historical data, automatically generated when the userselects a system from the tree. After the user selects the system, the user can select a datarange of the past hour, day, week, or months’ worth of data. These graphs provide an accurateview of overall, long-term system performance.

Section 4: Measurement and VerificationMeasurement & Verification (M&V) MethodologiesThis section contains a description of the types of Measurement and Verification (M&V)methodologies that Johnson Controls will use to guarantee the performance of this project.They have been developed and defined by three independent authorities:• International Performance Measurement and Verification Protocol (IPMVP)• Federal Energy Management Program (FEMP)• American Society of Heating, Refrigeration, and Air-Conditioning Engineers(ASHRAE) Guide 14PThere are four guarantee options that may be used to measure and verify the performance of aparticular energy conservation measure. Each one is described below.Option A – Partially Measured Retrofit IsolationSavings are determined by field measurement of the key performance parameter(s) which define theenergy use of the system affected by the FIM and estimate of other parameters.Savings are determined through engineering calculations using short term or continuous preand post-retrofit measurements of key operating parameter(s) and estimated values. Estimatescan be based on historical data, manufacturer’s specifications, or engineering judgment.Option B – Retrofit Isolation with Ongoing MeasurementsSavings are determined by field measurement of the energy use of the FIM-affected system,separate from the energy use of the rest of the facility.Savings are determined through engineering calculations using short-term or continuous preand post-retrofit measurements.Option C – Whole Building Metering/Utility Bill ComparisonsOption C involves the use of utility meters or whole building sub-meters to assess the energyperformance of a total building. Option C assesses the impact of any type of improvementmeasure, but not individually if more than one is applied to an energy meter. This optiondetermines the collective savings of all improvement measures applied to the part of the facilitymonitored by the energy meter. Also, since whole building meters are used, savings reportedunder Option C include the impact of any other change made in facility energy use (positive ornegative).Option C may be used in cases where there is a high degree of interaction between installedimprovement measures or between improvement measures and the rest of the building or theisolation and measurement of individual improvement measures is difficult or too costly.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.177

This option is intended for projects where savings are expected to be large enough to bediscernible from the random or unexplained energy variations that are normally found at thelevel of the whole facility meter. The larger the savings, or the smaller the unexplainedvariations in the baseline, the easier it will be to identify savings. Also, the longer the period ofsavings analysis after installing the improvement measure, the less significant is the impact ofshort-term unexplained variations. Typically, savings should be more than 20% of the baselineenergy use if they are to be separated from the noise in the baseline data.Periodic inspections should be made of all equipment and operations in the facility after theimprovement measure installation. These inspections will identify changes from baselineconditions or intended operations. Accounting for changes (other than those caused by theimprovement measures) is the major challenge associated with Option C-particularly whensavings are to be monitored for long periods.Savings are calculated through analysis of whole facility utility meter or sub-meter data usingtechniques from simple comparison to regression analysis.Option D – Calibrated SimulationOption D involves the use of computer simulation software to predict energy use. Suchsimulation models must be “calibrated” so that it predicts an energy use and demand patternthat reasonably matches actual utility consumption and demand data from either the base-yearor a post-retrofit year.Option D may be used to assess the performance of all improvement measures in a facility, akinto Option C. However, different from Option C, multiple runs of the simulation in Option D allowestimates of the savings attributable to each improvement measure within a multipleimprovement measure project.Option D may also be used to assess just the performance of individual systems within a facility,akin to Option A and B. In this case, the system’s energy use must be isolated from that of therest of the facility by appropriate meters.Savings are calculated using energy use simulation models, calibrated with hourly or monthlyutility billing data and/or end-use metering.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.178

Selecting M&V Options for a Specific ProjectThe tailoring of your specific M&V option is based on the level of M&V precision required toobtain the desired accuracy level in the savings determination and is dependent on:• The complexity of the Facility Improvement Measure• The potential for changes in performance• The measured savings value.The challenge of the M&V plan is to balance three related elements:• The cost of the M&V Plan• Savings certainty• The benefit of the particular conservation measure.Savings can also be non-measured. If savings are non-measured, these savings are mutuallyagreed upon as achieved at substantial completion of the respective energy conservationmeasure and shall not be measured or monitored during the term of the performance contract.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.179

Recommended Performance Verification MethodsJohnson Controls’ performance verification methods are designed to provide the facility’sadministration with the level of M&V necessary to protect them from an under-performing facilityimprovement measure (FIM), yet have a minimal impact on the project’s financial success.The selection of the M&V methods to be used is based on the criteria as detailed by IPMVP andFEMP, and Johnson Controls’ experience with hundreds of successful performance contracts inthe federal, state, and private sectors.

Operational Savings EstimatesBased on the recommended measures and improvements and a thorough analysis of theoperational expenses at the District over the past three years the following operational costsavings have been included in the financial analysis of the potential project. There are limitedcost savings for mechanical measures due to the District’s on-site HVAC technician whoperforms the majority of necessary repairs and maintenance on the equipment; therefore, nooperational savings have been claimed as part of this project.Potential Revenue Generation EstimatesRebatesAs part of the ESP for Spotswood Public Schools several avenues for rebates and incentiveshave been investigated which include:• NJ Smart Start Equipment Incentives• Pay for PerformanceNew Jersey Smart Start Equipment IncentivesThe New Jersey Department of Clean Energy has created an incentive program for customersthat provide rebates for the installation of qualifying energy efficient equipment. The followingtypes of equipment are included under this incentive program:• Electric Chillers• Gas Cooling Equipment• Desiccant Systems• Electric Unitary HVAC• Ground Source Heat Pumps• Gas Heating• Variable Frequency Drives• Natural Gas Water Heating• Premium Motors• Prescriptive Lighting• Lighting Controls• Refrigeration• Other Equipment Incentives• Performance Lighting• Customer electric and gas equipment incentives© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.195

This program works in conjunction with the Pay for Performance program, which is describedbelow, and cannot be used for measures that are used for Pay for Performance projectsAt this time, JCI anticipates Pay for Performance being a viable option for all schools and noincentives have been calculated for the SmartStart Program at this time.Pay for PerformanceJohnson Controls is a partner in the New Jersey Pay for Performance Program. This programallows school districts to obtain rebates for energy savings projects above and beyond thestandard NJ Smart Start program when energy savings exceeds 15% of the baseline usage foreach school. Based on the calculated energy savings, $366,276 have been selected forapplication to the Pay for Performance Program.The improvements recommended for the remaining schools will be submitted to the New JerseySmart Start program for all applicable incentives. The tables below are a summary of theanticipated Pay for Performance incentives that will be applied to the project. The 2011 Pay forPerformance worksheets have been used in the analysis of savings for this project.Spotswood High SchoolMemorial Middle SchoolIncentive #1 $14,846 Incentive #1 $6,584Incentive #2 $112,154 Incentive #2 $11,306Incentive #3 (Projected) $112,154 Incentive #3 (Projected) $11,306Appleby Elementary SchoolSchoenly Elementary SchoolIncentive #1 $5,216 Incentive #1 $5,000Incentive #2 $29,535 Incentive #2 $14,321Incentive #3 (Projected) $29,535 Incentive #3 (Projected) $14,321© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.196

For manyschools, the only way to shed load is to transfer electric load to a generator installed on sitebecause the learning environment cannot be interrupted by shutting down lights, HVACequipment, etc. At Spotswood Schools, only the High School has an emergency generator thatcould be used for peak shedding, which severely limits the potential for revenue generationthrough demand response.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.197

Participation in the PJM Demand Response program has not been recommended forSpotswood Public Schools due to the relatively small potential for revenue generation and thesubscription costs associated with implementing additional software to actively partake in theprogram.A summary of the anticipated incentives and revenue generation can be found below in Table 3.Table 3.

Section 6: District SupportMaintenance Impacts/ On-Going ServiceNew pieces of equipment that are installed as part of the ESIP project will be provided with thestandard manufacturer warranty. Once installation of the equipment is complete, the remainingwarranty period will be transferred to Spotswood Public Schools; any warranty issues will behandled directly with the equipment manufacturer rather than Johnson Controls.The installation of the recommended measures will reduce the amount of emergencymaintenance required by the district through the installation of new equipment; however,preventative maintenance is still required in order to ensure the correct operation of theequipment for the expected lifetime. A service agreement cannot be included as part of thisproject per the New Jersey Local Finance Notice 2009-11. Once the scope is finalized and bidsare received, Johnson Controls will assist the District in preparing bids for any preventativeservice agreement that is felt necessary for the new equipment. The service agreement willcover recommended maintenance per each equipment manufacturer. Training on the propermaintenance and operation of each piece of equipment has also been included as part of theESIP project which will allow the District to complete the majority of maintenance and repair inhousein order to utilize District resources.Design and Compliance IssuesAs part of the bidding process and ESP development, Johnson Controls is working with a Stateof New Jersey registered architect and professional engineer to ensure that all design andcompliance issues have been encompassed in the ESP and that any recommended measureswill meet all applicable codes. These services have been included as part of the ESPdevelopment.Customer RisksThe equipment recommended for replacement has been evaluated and compared to theASHRAE rated life. The boilers at the schools have exceeded the rated life as published byASHRAE and could fail at any time. If they are not replaced as part of this project, thereplacement could result in a large capital outlay in the near future. Similarly, the roofs at theschools have been evaluated as part of the project and are in need of repair/ replacement. Byincluding the roofs in the ESIP process, the District can manage the cost of the upgrades byoutlaying the costs over a period of time rather than in a large capital cost at one time.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.211

Appendix 2: Savings CalculationsWe have included a CD at the end of this section with all of the Savings Calculations associatedwith this ESIP. Additionally, this section provides the eQuest report and examples of selectsavings calculations.eQUEST Calibration ReportBackgroundeQUEST allows you to perform detailed analysis of today’s state-of-the-art building designtechnologies using today’s most sophisticated building energy use simulation techniques butwithout requiring extensive experience in the art of building performance modeling. This isaccomplished by combining a building creation wizard, an Energy Efficiency Measure (EEM)wizard, and a graphical results display module with a simulation engine derived from anadvanced version of the DOE-2 building energy use simulation program.eQUEST performs an hourly simulation of the described building for a user-selected weatherstation for a one-year time period. Using standard ASHRAE principals, heating and/or coolingloads are calculated based on contributions from walls, windows (including detailed shading),people, plug loads, and ventilation air for each hour of the year. The model then simulates theperformance of fans, pumps, chillers, boilers, and all other energy-consuming buildingcomponents as they respond to the building environment and controls. During the simulation,the energy use is tabulated for each of the end uses including lighting, general spaceequipment, heating, cooling, ventilation, and pumping and can be displayed in tabular orgraphical outputs as displayed below.Modeling SoftwareeQUEST (DOE2.2) version 3.64 Build 7130Weather FilesFor purposes of calibration, the following weather files were used:Hourly data from the 30 year TMY weather file recorded at the Newark, NJ, weather station.Utility DataFor purposes of calibration, the following utility data was used:• For Schoenly ES, Appleby ES, and Memorial MS, historical utility data from September2010 to August 2011 were used for both electricity and natural gas.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.219

• For the High School, where more recent electrical consumption data was not available,historical utility data from the period of June 2007 to May 2008 for both electricity andnatural gas.Modeling Methodology and InputsModelingThe following steps were taken to create the eQUEST model for the buildings at these schools:1. A detailed architectural model was built of the facilities based on drawings provided bySpotswood Public Schools, photos taken at the site, satellite imagery, and siteinspections. Site inspections included assessment of roof condition and verification ofglass types. The eQUEST model renderings are provided below.2. Lighting demand and energy was input based on the Johnson Controls lighting surveysand wattage measurements. The details of the lighting survey are included in theappendix of this report. Examples of field measurements are included below andwattage measurements are included in the appendix of the report.3. Representative internal equipment loads were incorporated into the model. Themiscellaneous equipment load accounts for computers and office equipment, hair dryersand other plug loads, and welding and other shop equipment throughout the facilities.The High School campus also has natural gas end-uses in the Kitchen and Auto Bodyshop, which are metered separately from the gas used in the boiler room. These useswere modeled as internal energy load in the space with a corresponding fractionalschedule to adjust the consumption each month.4. HVAC equipment and efficiencies were added and each zone was assigned to theappropriate HVAC system. Zoning was determined based on the mechanical floor plansprovided by the school district. HVAC equipment efficiencies were based on as builtdrawings provided by the school district. Examples of zoning layouts, HVAC systemdetails, and overall heating and cooling systems are provided below.5. Lighting, equipment, and HVAC schedules were added based on hours of operationsdetermined by data logging and by interviewing facility personnel and are providedbelow.Building Shell, Mechanical, Electrical, and Plumbing SystemsAll information pertaining to the layout of the building and zoning was taken directly fromarchitectural, mechanical, electrical, and plumbing plans provided by the school district. Thisinformation was cross-checked with information gathered during the field audit of the facilities.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.220

Typical eQUEST HVAC System SchematicsThe following system schematic from eQUEST represents the components modeled for thedifferent system types. Packaged single-zone units are common at the facilities throughout thisschool district. This system type has natural gas-fired heating, DX cooling with an air-cooledcondenser, constant-speed supply air fan with economizer cooling control of the outside airdamper. The schematic for the packaged variable volume units look very similar to the constantvolume single-zone units, except there is variable volume control of the supply air, the dischargeair temperature is controlled to 55 F, and there are reheat coils at the zone level. The variablevolume units, however, have a gas-fired furnace section, DX cooling and air-cooled condensersimilar to the setup in the single-zone units.Packaged Single-Zone System SchematicThe following schematics represent the other system types common throughout the District. TheH&V systems typically consist of a unit containing a hot water heating coil and a supply fan. ThePTAC systems are similar to unit ventilators except that they have DX cooling coils with remoteair-cooled condensers. Heating for the PTAC units comes from hot water heating coils.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.231

Typical eQUEST Central Plant LayoutTypical Hot Water SystemThe hot water system serving the Admin addition at the High School is modeled with one boilerserving a hot water system for the coil in RTU-14A and the VAV box reheat. The model forMemorial Middle School contains two separate hot water loops, each with hot water boilersassigned with types and capacities reflecting actual field conditions. Likewise, at SchoenlyElementary, the existing hot water system is modeled with a hot water boiler simulatingperformance of the boiler found on site.The central plant systems at Appleby are simulated with water-to-air heat pumps assigned tothe geothermal well loop. Due to modeling limitations in eQUEST, the air handlers and unitventilators on the dual-temperature loop had to be modeled with central plant equipment (boilersand chillers) serving the loops. This equipment simulates the existing water-to-water heatpumps, and has been assigned electric EERs and COPs to match the performance of theexisting equipment. This modeling method allowed us to model the unusual system types foundat this school and obtain a close calibration with the electric bills.Operating SchedulesSchedules and temperature settings were based on logger data and interviews with facility anddistrict staff. Maximum space occupancy was based upon information from design drawings,where available, and from the field. Actual numbers of occupants in the spaces were based onquantities provided by the school district. Lighting usage was based on field survey informationas well as lighting wattage measurements and standard operating hours of the building basedon information provided by the District. The following schedules and assumptions were used inthe eQUEST model to complete the baseline calibration.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.233

OccupancyOccupancy schedules are modeled as a fractional schedule in eQUEST. This allows theprogram to adjust occupant levels throughout the day and throughout the year. The occupancyschedules were based upon known campus operating schedules. The following chartrepresents the occupancy schedule used at both campuses for days when school is in session.For days when school is not in session, during weekends, holidays, and the summer, very lowpercentages are used to account for any miscellaneous low levels of building occupancy.FacilityMaxOccupants(Design)OccupantQty.(Actual)OccupancyPercentHigh School 1,117 870 77.9%Middle School 856 381 44.5%Schoenly 552 273 49.5%Appleby 967 552 54.0%Lighting SchedulesDuring the detailed audit, several measurements were taken to confirm actual powerconsumption and run time of various pieces of equipment.

Air-Side HVAC SchedulesAir-handler fan operation is simulated using an on/off schedule in eQUEST, where “on” makesthe AHU fan available for operation if there is demand from any zones that the unit is serving.The following chart indicates the average system operating schedule used in both models.Each conditioned space is assigned heating and cooling setpoint schedules in the model. Thefollowing graphs indicate the typical setpoint schedules used in the models for days when thebuilding is occupied. During all other days, which include weekends, holidays, and summers,the setpoint schedules do not set the temperature to “occupied” mode but maintain the“setback” temperature.HVAC system operating schedules were based on logger data obtained for a two-week periodduring the IGA project development phase. The schedules were then adjusted during modelcalibration to obtain operating schedules representative of average system operation during thecourse of the past year.Spotswood High SchoolData from AHU Fan Loggers is shown in red text.RTUs – AllUnitsRTU-16 (old RTU-1) Classroom 301RTU-17 (old RTU-2)Classroom 301ARTU-18 (old RTU-3) Classroom 302RTU-3A (old H&V) Shop 305, 306 & 308RTU-4 Graphic Design 306RTU-5A Life Skills 303RTU-6A Child Care Rm. 304RTU-7A307A-307DRTU-13A Science Rms. 602, 606 & 608RTU-14 Science Rms. 601, 603 & 605RTU-6 Rm 406-409RTU-7RTU-8RTU-10RTU-11Guidance OfficesFront OfficesNight Setback SchedulesExisting Occupancy ModeArea ServedSchedule1/3 of Media Center + Rms. 501- 505 + 515, 516 & 516A1/3 of Media Center + Rms. 505- 511 & 517Year-round: On 24/7© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.235

UnitRTU-14 Cares Classroom 100RTU-15Admin OfficesNight Setback SchedulesExisting Occupancy ModeArea ServedScheduleCalibration MethodologyCalibration1. The first step in the calibration process is to match the electric demand of the model tothe historical electric demand based on utility bills. Matching the demand ensures thetotal installed electric load (lighting, miscellaneous equipment, HVAC equipment) iscorrect. A three step process is employed to bring the demand within the calibrationguidelines:a. Reasonable adjustments to miscellaneous equipment loadsb. Reasonable adjustments to electric HVAC equipment efficienciesc. Verify the outside air ventilation levels are reasonable2. Once the demand is calibrated, the next step is to calibrate the electric energyconsumption. Schedule values for lighting, equipment, and occupancy are adjusted tobring the electric consumption within the calibration guidelines.3. The final step in the calibration process is to bring the fuel consumption into agreementwith historical utility data. This is done after the electric calibration to ensure that theinternal loads from lights and miscellaneous equipment are correct.Calibration Resultsa. Calibrating the gas is first done by matching the gas consumption during thewinter months by adjusting outdoor air ventilation and scheduling as needed tobring the model into agreement with historical data.Once a simulation has been completed, you visualize the results through a number of graphicalformats. Overall building estimated energy use can be seen on an annual or monthly basis.Detailed performance of individual building components may also be examined. The followingfigures show the monthly electrical and gas consumption for the baseline building simulationand the fraction of that consumption attributed to each of the end-use categories.The following tables and graphs represent a comparison between the actual billing data and theresults from the eQUEST model. For calibration purposes, an overall error less than 10% is© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.242

desirable to ensure an accurate representation of how the building is operating. The errorbetween the model and the actual utility bills is usually a result of unique weather occurrencesthat cause the bills to differ from the 10 year averaged used in the model. Deviation from thepast 12 months of historical utility data can also be attributed to irregularities common inbuildings with industrial equipment and manual HVAC controls.This is because equipment common in technical schools, such as welding equipment, may beused more often during certain parts of the semester than others, depending on the structure ofthe curriculum. These end-uses cannot be easily predicted and therefore, cannot be easilyaccounted for in the model. Also buildings with manual HVAC controls may experience timeperiods where equipment is accidentally left on.© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.243

After creating anew building description, you can create parametric runs to quickly describe a series of designalternatives to the baseline building description. You can then automatically simulate any or allof these alternative cases and view the simulation results as either individual or comparativegraphs or in a detailed parametric tabular report.Once the model is calibrated to the historical utility data as described above, savings werecalculated by changing certain parameters within the model. There are several advantages toutilizing a modeling tool such as eQUEST to calculate savings. By comparing the baselineconsumption to historical data, one can be assured that the savings calculations are reasonablewhen compared to the baseline. Secondly, calculating savings in order allows the interactions tobe included within the model. For example, during a lighting retrofit the overall electric energy is© 2011, Johnson ControlsDo not copy (physically, electronically, or in any other media)without the express written consent of Johnson Controls.258

educed to the system. When the new lighting system is in place, the lighting heat load will notbe as great causing the heating system to not work harder, which uses less energy. By onlyusing spreadsheet calculations, these interactions are not always included.In addition to system interactions, completing one savings measure will have an effect on allother savings measures. A central plant savings measure or overall building savings measurewill have an effect on the baseline of each measure completed afterward. Using the eQUESTmodel, these changes in baselines are very apparent and allow for the most accurate savingscalculations possible. The savings parameters used for the purpose of calculations are detailedin the appendix to this report.Savings Results – Spotswood High SchoolRunPeak Electric(kW)Electric EnergyTotal (kWh)Fuel Total(Therm)Savings Relative to Previous MeasureBaseline Adjust 45 130,631 (2,142)Lighting Retrofit 56 155,172 (2,726)Lighting Controls 16 108,473 (1,553)RTU-8 Elect to Gas Heat 0 44,366 (2,832)L4L Media Center Replacement 13 15,546 -Media Center PVVT Conversion 27 149,233 (2,572)RTU-5 and 6 Replacement 5 5,334 -RTU-5 and 6 VVVT Conversion 6 17,846 (174)Remaining Carrier Replacement 23 23,617 -Apply Fan Schedule (7) 54,014 (16,577)Heating/Cooling Setback (8) 126,575 12,930DCV - FOR INTERACTION 20 10,071 11,659Roof Replacement 3 19,114 4,323Front Window-Wall Replacement 4 7,339 490Note: Items listed in green are not carried forward into the next run, as they are not expected to be includedin the project.
