PACIFIC GAS & ELECTRIC has been investigating the 

advantages of utilizing emerging technologies, and performing an 

analysis of their associated energy savings. Upon being 

approached by Kaiser Permanente & Petaluma Valley Hospital for 

the installations of operating room LED (Light Emitting Diode) 

lighting fixtures a study was commissioned to determine the true 

savings of this application, and the associated economic benefits. 

The LED’s would replace their existing halogen surgical lights in the 

hospitals’ operating rooms. This study captured both the direct 

savings from the lower electrical demand equipment and the 

indirect savings from the associated HVAC loads. 

THE PROPOSED LED surgical lights would consume 54% of the 

energy required by halogens. Other significant benefits of the LED 

fixtures are an adjustable beam temperature (i.e. color), they are 

not subject to immediate burn out and the bulbs have a longer 

useful life. 

Executive Summary 

ADDITIONAL ENERGY BENEFITS to the direct power reduction for the LED lighting is in the reduced HVAC load for the 

associated hospital’s equipment. However, because of the way each of the hospital’s HVAC systems is currently controlled, the 

controls would require a minor setpoint adjustment to realize these additional savings. The HVAC system in both facilities is a 

constant volume system with reheat, which has constant supply air temperature setpoints. With the removal of the lighting’s heat 

load the reheat will increase in gas load of 1 therm/10 kWh of direct savings in lighting, unless the supply air temperature setpoint is 

raised to compensate for the reduced heat from the light fixture. By changing their associated setpoints the available indirect 

energy savings can be realized. The associated savings are 1 therm in gas and 17 kWh in HVAC savings for every 24 kWh of direct 

lighting savings. 

OPERATING ROOM LED FIXTURES have high first costs: $20,000 for each Halogen fixture and $27,000 for each LED fixture and 

have a lifespan of 15 years (for the fixtures). Because of the high cost of the fixture, the benefits associated with replacement based 

on just energy savings are not economically viable. However, if a replacement is performed there are real savings. LED 

Replacement savings are summarized as follows for Kaiser’s 12 Operating rooms, which are proportional to Petaluma:

BACKGROUND 

Pacific Gas & Electric has been investigating the advantages of 

utilizing emerging technologies, and have been performing an 

analysis to evaluate their true associated energy savings. They 

were approached by a number of hospitals for a proposed 

installation of LED lighting fixtures to replace their existing 

halogen surgical lights in their operating rooms. Of these 

facilities, PG&E determined to utilize Kaiser Permanente 

and Petaluma Valley hospital for their pilot program to 

commission a study for this application of this emerging 

technology. The goal of this study was to establish the 

total savings attributed to the fixture replacement. From 

this data the utility will determine how to incent these 

installations and the degree by which to encourage future 

installations. 

The study consisted of: 

1. A field study to establish the true baseline at both facilities. 

Operating Room Lighting Replacement 

2. A paper study of the associated savings of these 

installations. 

3. A study of the associated lighting quality. 

4. A metered study solely at Petaluma Valley Hospital to 

establish that the associated saving would be uniform. 

This study analyzed the true savings associated with the retrofit and 

its associated economic analysis. It has been designed to allow its 

application to be applied to future installations. 

FACILITY AND CURRENT CONDITIONS 

Kaiser’s 2425 Geary surgery center consists of 12 operating rooms 

on the 4 th floor of the facility. They are all located along a common 

corridor, and two of them were retrofitted from storage facilities. 

Appendix I contains the associated internal loads with each, as 

established by a field survey on May 1, 2009. 

Figure 1: Kaiser Operating Room 

Figure 2: Operating rooms have high equipment loads 


Page 2


The operating rooms are served by two air handlers (AHU 5 & 7). Air Handler 7 handles 8 of the 12 operating rooms, 

and an even higher percentage of the required air; 74%, or 12,637 CFM, based on the May 31, 2009 air balance. This is 

57.7% of the 21,900 CFM air handler’s capacity. Air handler 5 is a 21,200 CFM air handler, which distributes a total of 

4,435 CFM to the remaining 4 operating rooms. The operating rooms are constant volume, 100% outdoor air units 

with hot water reheat. All of the air handlers in the hospital are served by a common chiller and steam boiler plant. Air 

is supplied overhead around the patient and onto the surgeons, and returned at floor level at the perimeter of the 

operating room. The schedules associated with this equipment are available in Appendix I. 

Figure 3: OR Supply Grille 

The units are controlled by a Johnson Controls Metasys system. 

Local control and thermostats are located in each of the surgical 

suites. The operating rooms are maintained in condition appropriate 

for surgery at all times. Room temperature is controlled by resetting 

the air handler’s supply air temperature to meet the maximum load 

on the system, and then incorporating reheat to obtain the required 

condition for the operating room, which typically is kept between 

65°F and 68°F. No humidity control is currently utilized. This 

control strategy has also been utilized at Petaluma Valley Hospital, 

although with a Delta Control system. 

The chiller plant consists of three water cooled chillers: 2 Centrifugal York chillers at 450 and 250 tons, and 1 150 Ton 

York YT screw chiller. These chillers are being utilized at a 43 degree supply temperature and a 20°F delta T. When 

load is increased facilities usually lowers the supply temperature. The heating hot water plant consists of 2 Bryan 

LMB750 steam boilers. The field readings indicate a supply of 320°F and 10 psi, and a return temperature of 120 F. 

Currently the associated air handlers are not meeting the requested setpoint. When plant field readings were taken the 

outdoor air temperature was above the limit of the air handlers, and the units were unable to hold the requested 

setpoint of 53°F. Air handler 5 was at 57.5°F, and air handler 7 was at 58.6°F. These units have passed their 

expected lifespan, and will be replaced. The new design will not be a direct replacement, but a transition to a common 

152,000 CFM air handler with a fan motor over 200 HP. 

Petaluma Valley Hospital’s surgery center consists of 4 operating suites, the layout of which is available in Appendix 

II. The operating rooms are denoted as Operating Rooms 1-3 & ORTHO. The facility is a two story hospital, with the 

surgical facilities being on the first floor. These are served by a single two speed air handling unit. Appendix III 

contains each OR’s specifications, the metered supply and return air data and the associated economic analysis of the 

OR LED replacement. Note that although the surgical suites are only utilized 68 hours a week, they must be 


Page 3


maintained ready for surgery at all times. The operating rooms are constant volume, 100% outdoor air units with hot 

water reheat. The operating rooms at Petaluma pull a much lower percentage of the total air supplied by the air 

handler than Kaiser: 7%. The chiller plant consists of a 200 ton air cooled Trane reciprocating chiller and an 80 ton 

BAC ice chiller. These chillers are being utilized at a 42 degree supply temperature and a 16°F delta T. 

SURGICAL LIGHTS 

Each of the operating rooms contains two to three 

surgical lights, whose energy consumption is 

summarized in Table 1 (Petaluma is available in 

Appendix II). Pictures of these OR lighting fixtures may 

be seen in Appendix I. These Skytron halogen fixtures 

have a service life of 15 years and the majority will soon 

be in need of replacement. There is the possibility of 

early retirement if an adequate energy saving will justify 

it.

The lights output is controlled locally at a wall mounted 

knob (Figure 2). Dimmer knobs are also mounted 

directly to the fixture. 

Since these lights will need to be replaced in the near 

future an analysis of what type of fixture will replace 

the existing one was conducted. The two analyzed 

were LED OR lights and an in kind replacement of the 

existing halogen fixtures. 

Halogen lights have a number of problems with them: 

beam temperature, immediate failure, additional energy 

costs, and inability to adjust color. The beam 

temperature is critical as radiation is reduced, thus the 

surgeons are more comfortable, and the patient’s 

exposed tissue will not dry out as quickly, allowing 

longer surgeries. Halogen bulbs fail instantaneously, 

while LEDs dim out, so a catastrophic failure will not 


occur and replacement can be scheduled. With beam Figure 5: OR Surgical Light Control Panel 

temperature adjustment LEDs can change their color, 

thus allowing ideal contrast for each procedure. This may allow superior outcomes for the patient. 

RESULTS 

There is a definitive direct saving in installing LED Lights into the operating rooms. Tables 2A & 2B summarizes these 

savings. An interesting note is that for the LED fixtures it doesn’t matter if it s a large or small luminaire, either way the 

consumption is 144W per fixture. This was pulled directly from Skytron’s product catalog (Appendix III), which is a 

likely manufacturer for this replacement.

The final column in the above tables shows the direct savings associated with an LED lighting replacement. As the 

removal of these lights will reduce the load on the HVAC systems at the hospital an indirect savings calculation was also 

performed. The findings of this was that without a change in control setpoints the installation of the OR LEDs will 

cause no further electrical savings and a net increase in natural gas consumption. An explanation of these savings is 

available in Appendix IV. This is due to the operating rooms requirement of constant volume of air. In order to meet 

the required setpoint for the room the supplied air is reheated by the campus’ steam loop to the required temperature. 

Previously the operating room lights were providing a portion of this reheat, and with their removal the load will be 

transferred to the boiler plant. This averages an additional 0.1 therms/kWh saved. 


Page 6


The operating theaters are the defining load on the air handlers, which dictate the setpoint of the supplied air of the air 

handler. If the operators adjust the setpoint of the supplied air to compensate for the drop in load there will be both 

electrical and thermal savings; an average of 0.69 kWh and .04 therms/direct kWh of reduction. Tables 3 and 4 

illustrate these savings. Petaluma’s results by OR are available in Appendix II, as well as the full calculations & 

supporting documentation. Kaiser’s calculations and supporting documentation is available in Appendix I. Note that 

the basis of the positive value without a controls change for Kaiser’s OR 6 is that the currently supplied cooling for that 

OR is greater than the supplied cooling.

CONCLUSIONS AND RECOMMENDATIONS 


With an LED initial cost of $27,000/fixture and service life of 15 years an early retirement based on energy savings is 

not economically viable. Halogen replacement fixtures cost approximately $20,000. The incremental cost associated 

with this still will not justify their implementation based solely on energy, but the reliability of the fixtures and the other 

associated benefits warrant LEDs as a viable alternative at the end of the existing fixtures service life.

Focusable LED Lighting 

Page 47

Bright, Cool, Comfortable 

Color correct for every procedure. It’s like having two lighting systems in one! 

Surgeons can choose a Color Temperature of 4,000K (soft white) or 4,500K (bright 

white) to best suit individual needs. Aurora's Color Rendering Index (CRI) is 94. 

Optics provide bright and cool illumination with a lighting intensity of 106,490 lux 

(LED5) or 133,000 lux (LED7) per surgical lighthead. 

Minimal energy output keeps surgical conditions bright as well as comfortable, 

even for extended cases, translating also into years of energy cost savings. 

Focusable LED (Light Emitting Diode) lighting extends illumination range while 

retaining maximum intensity for greater distances such as those required for Ob-Gyn, 

Orthopedics, Vascular and Urology. 

Optimally bright, cool and color correct for surgeons and the entire surgical team. 

Redefining the term “bulb” life. Aurora LED pods are not bulbs and they do 

NOT “burn out”. LED Pods retain 90% of their original intensity even after 10 years 

(20,000+ hours) of use. 

Technology Leadership. Aurora LED is the ultra efficient, "Green Technology" 

surgical lighting system that conserves energy while providing bright, high intensity 

lighting for every procedure.

technology (CMRT). Aurora's advanced optics provide cool, 

high intensity lighting without glare, with excellent shadow 

control. Heat is the number one enemy of LED performance 

and longevity. By design, Aurora’s individually suspended 

LEDs are protected from heat, assuring maximum 

performance for the life of the LEDs. 

LED Pod 

Multiple LED pods (each equipped with 

7 LEDs and advanced cold mirror reflector 

optics) culminate together to deliver 

hundreds of high intensity lighting segments, 

forming a high intensity column of bright and 

focusable light to the surgical field, with 

superior shadow control and without glare.

Leadership and Energy Savings 

Aurora LED is as brightly illuminating to the surgical field as it is to your 

Operating Budget. Aurora provides 

high intensity lighting year after 

year with very low energy 

consumption, including LED 

lighting pods that retain 90% 

original intensity even 

after 10 years 

(20,000+ hours) 

of use. 

Aurora LED Pod 

LED requires 

less than 1/2 the energy needed 

to power traditional halogen systems!

Optics Advantage 

Extended working distances (beyond one meter) 

are not uncommon for several surgical procedures, 

including Ob-Gyn, Orthopedics, Vascular and 

Urology. Just a 1/4 turn of the sterile focus handle 

captures maximum intensity at any distance with 

unmatched lighting flexibility range and without 

having to reposition surgical lightheads. 

Bright, Cool, Color Correct Lighting at any distance and 

for every procedure. 

Flexibility 

Aurora LED provides featherlight maneuverability 

along with 360° rotation at all points of articulation, 

including 20° upward vertical movement for 

taller surgeons and 90° downward flexibility to 

deliver bright, cool and color correct lighting 

where it is needed most.

Air Handler Operation for Equipment Removal 

This section is available as background to clarify why an increase in utility energy consumption will occur with the 

removal of internal loads from an operating room (OR). As seen in Figure A6-1 each air handler services a number of 

Operating Rooms. Due to the codes dictating operating room airflow, each OR must be supplied with a minimum 

outdoor air supply, and thus is a Constant Volume 100% outdoor air assembly. These ORs all require a certain heat 

load to be removed, signified by the Q’s. Q is dictated by the internal load from equipment, lighting, occupancy, and 

other heat gain. In the example below OR 2 requires 7,560 BTUH to be removed. With the supplied air, an air 

temperature differential of 7° F between the supply and return is required to meet that load. Therefore, operating 

rooms 1 and 3 will require the supplied air to be reheated by the specified amount in order to meeting that room’s set 

point. If equipment is removed from either OR 1 or 3 their respective internal loads (Q) will be reduced, but the drop in 

cooling load will be picked up by the reheat coils. 

Figure A6-1: Air Handler Airflow Diagram 

OTHER AHU TYPES 

This is a different in single zone, multizone or VAV assemblies. For these scenarios an equipment load reduction is a 

direct decrease in HVAC load, and in the case of variable airflow system a decrease in fan energy. The reheat required 

to maintain setpoint will only occur under heating conditions
