MESSAGE FROM THESECRETARY OF ENERGYWelcome to the U.S. Department of Energy Solar Decathlon2009. We are proud to hold this unique competition and toshowcqse the possibilities of solar power and smart energy useon the National Mall. It is a personal pleasure for me to be apart of the Decathlon because it helps accomplish one of myhighest priorities: engaging the next generation of scientists andengineers to help solve the energy problem.These students are remarkable. For the past two years, they havebeen designing, engineering, building, and testing solar-poweredhouses that, ideally, will be self-sufficient. Using off-the-shelftechnology, the teams must produce enough electricity and hotwater from solar panels to run a modern home with all of theconveniences we've come to expect.Their work has important real-world applications. Homes andother buildings account for 40% of the energy we use in theUnited States- more than we use in transportation or industry.There is an incredible opportunity to design and construct livingand work spaces that are dramatically more efficient than thosewe build today. Competitions like this one can Ilead to newsolutions and inspire a new generation of problem solvers.This competition is also a powerful reminder of the potential of aclean energy economy. President Obama is committed to leadingthe United States toward a new energy future-to create jobs andensure our competitiveness, to reduce our dependence on foreignoil, and to reduce our greenhouse gas emissions. The skillsthese students have learned will be in increasing demand in theyears ahead.Table of ContentsWel co me to Solar Decathlon 2009.......... .. .................. ....... ....... 2 Exhibits and Events............... .............................. ....................... 3 Workshop Schedule ....................................................................3 Who's Who at Solar Decathlon 2009 ...... .............. ...................... 4 ALook at the Competition ................................................. .. ....... 5 Competition Schedule .. .............................................. .. ....... .. ..... 6 About the Technologies .......................... .. .. .......................... ...... 8 Wi-Milwaukee... .................... ............... ... ......... ........................ 10 Univ.of Louisiana ........ ............. ........ .............................. ..........11 Team Missouri ................. .. .... .. .................................... .. ..... .. ..... 12 Arizona ....... ....... .............. ..................................... .... ............... 13 Rice ....................... .. .. ...... .. ... .......... ... ........... .. ........................... 14 Team Alberta ..... ............................................. ........... ................ 15 Team Ontario/Bc.. ..................................................................... 16 Iowa State .......... .... ......................................... .................. .. ...... 17 Penn State .............................. .. .... ................. .. ...... .................... 18 Team Spain .. .......... ................................ .. .. .. ............ .. ............... 19 Kentucky....................................................................................20 Ohio State ........... .......................................... ............ .. ..... .. .. .. ....21 Team Boston ......... .... .. ...... .. .............................. .. .. ... ................. 22 Team Germany .................................... ................. ..................... 23 Virginia Tech .. ...... .. .. ...................... ...... .. .................................... 24 Cornell ............... .......................................................... .............. 25 Puerto Rico .......................................... .............. ....................... 26 Minnesota .................. .. ....... ...... .......................... .. ................... 27 Team California ......................... ................................................ 28 Illinois ..... ................................. ..... .......... ......... .. ....... .. ..... .. .... .... 29 U.S. Department of Energy ............ .. .. ...... ............. .. .................. 30 Organizer ............... ...... ......................................... ....... .............. 31 Sponsors ......... .. ................ ........................... ......... ....... .............. 32 The Solar Decathlon shows us what is possible today and pointsthe way to a brighter future.

WELCOME TO SOLAR DECATHLON 2009 Since 2002, the U.S. Department of Energy Solar Decathlonhas showcased design excellence in energy-efficient and solarenergy-powered home design. The competition challenges20 college teams from around the world to design, build,and operate the most attractive and efficient solar-poweredhouse. The teams spend nearly two years transforming ideasinto reality before transporting their masterpieces to theNational Mall in Washington, D.C., for the competition. Newthis year, all team houses are also connected to the utilitygrid to take advantage of net metering. The event providesvaluable learning experiences for student competitors andmarket-ready examples of solar and energy-efficient buildingtechnologies for the public.The Solar VillageTake advantage of the opportunity to see the amazingcompetition houses when their doors open to visitors Oct.9-13 and Oct. IS-18. Please note that the houses are closedOct. 14 for competition monitoring purposes. Feel free to askthe students questions, too. They are engaged and passionateabout their work.Walking through the houses, you can see examples ofenergy-saving techniques and technologies available today.Each house is designed to produce at least as much energyas it consumes, showing the true potential for solar power ineveryday living. These zero-energy houses are all connectedto the local energy utility, Pepco.About the TeamsThe teams competing this year hail from far and wide, withgreat representation from the U.S. (including Puerto Rico)as well as Canada, Germany, and Spain. Returning champsfrom Team Germany will try to extend their reign, whilenew contenders will raise the bar with innovations.

AROUT THE TECHNOLOGIESThe design strategies and technologies at work in the SolarDecathlon houses are intended to produce zero-energyhomes (ZEHs), which produce as much electricity fromrenewable sources as they consume. The Solar Decathloncompetition, and particularly the Net Metering contest,encourages teams to design for net-zero energy consumptionand redirect surplus energy into the utility grid. Somecommon technologies and products employed by the teamsare explained here.Energy-Efficient Lighting - Practical, affordable, andwidely available, compact fluorescent lamps (CFLs) areenergy-efficient lamps that work in standard incandescentfixtures and provide lighting levels comparable to those ofconventional lamps. Light-emitting diode (LED) lighting isa highly efficient strategy for supplementing daylighting.An LED can operate with increased efficiency for morethan 50,000 hours-50 times longer than an incandescentbulb. Although relatively expensive, LEDs present manyadvantages over traditional light sources, including lowerenergy consumption, longer lifetime, and smaller size.Energy Recovery Ventilators - Energy recovery venti latorsprovide fresh outside air while minimizing energy lossand costs. These ventilation systems transfer heat betweencooler and warmer air sources to regulate climate controland circulate air. There are two types of energy-recoverysystems: heat-recovery ventilators and energy-recoveryventilators. Whereas a heat-recovery ventilator transfersonly heat, an energy-recovery ventilator also transfers watervapor, thereby maintaining even humidity within the housethroughout the year.Ground-Source Heat Pumps - A ground-source heat pump(GSHP) is an energy-efficient central heating and coolingsystem that takes advantage of relatively constant groundtemperatures to draw heat to or from the ground, dependingon the season. Also known as a geothermal heat pump, aGSHP forces the transfer of heat by passing it througb aloop of refrigerant pumped through a vapor-compressionrefrigeration cycle. Because Solar Decathlon teams are notpermitted to break ground on the National Mall to installtheir own GSHP systems, they are simulating the earth withwater bladders.High-Performance Windows - Windows provide naturallight, but they can also negatively affect a home's energyefficiency. Low-emissivity (low-e) coatings for windowsare thin, transparent coatings of silver or tin oxide thatpass visible light through while reflecting infrared heatradiation into the room, which is particularly beneficial inwinter months. Efficiency can also be significantly improvedwith gas-filled windows. The space between panes is filledwith a colorless, odorless gas that transfers less heat thanair. Electrochromic technology allows homeowners toelectronically adjust the amount of light and heat that passthrough windows. A small voltage applied to electrochromicglass causes it to darken; reversing the voltage causes itto lighten. Darkening the windows in summer reducessolar heat gain; in winter, the windows lighten so sunshinebrightens and warms the house.Insulation - The type and placement of insulation areimportant considerations for energy efficiency becauseheating and cooling account for nearly half of a home'senergy consumption. A home's insulation is rated accordingto its resistance to heat transfer. R-value rates heat transferresistance-the higher the value, the better the insulation.U-value, generally used for rating windows, also quantifiesheat transfer-the lower values are better. The U.S.Department of Energy recommends ranges of R-values basefjon local heating and cooling costs and climate conditions.Visit enter your zip code for the recommended insulationlevels for your new or existing home.Passive Solar Design and Daylighting - By properly locatingand designing a home, you can naturally capture solarenergy and reduce the size of, or completely eliminate,mechanical systems for heating and cooling. Design elementinclude window overhangs and proper window sizing andplacement. South windows, for example, harness heat fromthe winter sun. Shading elements such as large overhangsand shrubbery minimize heat in the slimmer. Similarly,daylighting design features such as clerestory windows,glass doors, floor-to-ceiling windows, and skylights providenatural light for home activities and reduce the need forelectric lighting._ The U.S. Department of Energy Solar Decathlon 2009

•Phase-Change Materials - Phase-change materials can storeenergy efficiently within the walls and ceiling of a homeand are primarily employed for space heating and cooling.Materials with high melting points store heat (or cold)effectively and release it when the temperature changes byconverting a solid to liquid and vice versa. To cool a space,excess hot water or air is run over the phase-change material,which absorbs the extra heat and melts. To heat, the reverseoccurs, and the phase-change material solidifies, therebyreleasing heat into the space.Photovoltaics or Solar Electricity - When most people thinkof solar technologies, they think of solar thermal panels orphotovoltaic (PV) panels. PV panels generate electricityby absorbing light energy from the sun, which triggers anelectric current. Most commercially available PV panelsare made of silicon cells. Many currently available solarcells 'are configured as bulk materials that are subsequentlycut into wafers. Other PV materials are configured as thinfilms that are deposited on supporting materials. PV systemsare often situated on rooftops, but they can be installed onpoles or other structures with adequate exposure to the sun.The power they generate is measured in kilowatts (kW).Building-integrated photovoltaics are photovoltaic materialsthat replace conventional building materials in parts of thebuilding envelope such as the roof, skylights, and facades.Solar Water Heating - Solar water heaters are generally morecost-effective than PV and generate hot water for domesticuse. Solar water heating systems typically include storagetanks and solar collectors, which harness solar energy to heatwater or other fluids such as antifreeze. The heated water isstored in a well-insulated storage tank.Structural Insulated Panels - Made of foam insulationsandwiched between sheets of oriented strand board orother building material , structural insulated panels (SIPs)are prefabricated structural elements for building walls,ceilings, floors, and roofs. They provide superior and uniforminsulation compared with more traditional constructionmethods (e.g., stud or "stick frame") and offer energysavings of 12%- 14%. When installed properly, SIPs alsoprovide a more airtight dwelling, which makes a house morecomfortable and quieter. SIPs have not only high R-values butalso high strength-to-weight ratios.Harold Remlinger and Brian Eady install solar panels on the roof ofthe Solar Decathlon 2007 Lawrence Technological University house, (Credit: Kaye Evans-Lutterodtl Solar Decathlon) Important TerminologyEnergy Monitoring System s - Energy monitoring systemsare an efficient and effective way to survey a home's energyuse and trends. Greater control over and understanding ofenergy use means improved energy efficiency and reducedenergy costs. By knowing when a household demands themost energy-for example, in the evening hours whenmultiple appliances run concurrently- homeowners canalter their energy use habits to minimize energy costs andenvironmental impact.Greywater - Greywater is wastewater that originatesfrom domestic processes such as dish ,"vashing, laundry,and bathing. Recent concern over water consumption andtreatment and efforts at greater water efficiency have ledto the recycling of filtered greywater for domestic andagricultural uses, such as for garden irrigation or torflushing toilets.Net Metering - Net metering is a utility billing policythat encourages people to generate their own electricity. Itinvolves a single meter that spins forward when electricityis drawn from the grid and backward when electricity is fedto the grid. That way, electricity producers are effectivelycompensated at the retail rate for the electricity theysupply to the grid (as long as it is less than the electricitythey consume). Without net metering, self-generators aretypically compensated at a lower wholesale rate for theelectricity they produce.

101 I UNIVERSITY OF WISCONSIN-MILWAUKEE Team Web site: sd09Meltwater: ASand County Solar HouseAldo Leopold, author of the famous A Sand County Almanac,which promotes conservation and nature awareness in hishome state of Wisconsin, would be proud of the students onthe University of Wisconsin-Milwaukee's Solar Decathlon2009 team. Their house not only is designed to mimic theglacial-carved lines of their rolling landscape but also is builtfrom construction waste materials-including some timberplanted by Leopold himself- from the LEED Platinum AldoLeopold Foundation headquarters near their campus.Drawing Inspiration From Nature"The line of our inverted butterfly ~ shaped roof representsthe valleys and hills created by glacial water," says EricHarmann, architecture project manager and graduatestudent. "The rain screen is a representation of the rivers."The inverted roof channels water into a reflecting pool,which irrigates plants on the deck. After the competition, acistern system will harness rain to water marsh and prairiegrasses nearby.Room With a ViewThe team designed windows and a large glass-door wallto bring in natural light and ventilation. A 12-by-7-ft(3.7-by-2.1-m) glass door opens to the west. This seemscounter-intuitive to controlling heat from afternoon sun, butthe door allows views of the Washington Monument duringthe competition and views of the Menomonee Valley inMilwaukee. The door is protected using automated, verticalsunshades, and all of the windows are triple-paned low-ewith argon-filled glazing to control heat from the sun.Eco-Friendly MaterialsMaterials from the Aldo Leopold Foundation provide theflooring, much of the casework, exterior cladding, anddoors- primarily Forest Stewardship Council-certified forsustainability practices. The team believes this will be thefirst building in the country to use Paperstone- a "wood"product made, in this case, out of recycled paper from theuniversity's schools of architecture and engineering-for theframes and sashes of its windows.Thermostats EverywhereAs part of the heating and cooling system, multiple sensorstake temperature measurements that are averaged forconstant monitoring. The house has two heating, ventilation,and air conditioning (HVAC) zones, so adjustments can bemade efficiently. "Ideally, this will allow us to reduce theon-and-off cycling of the HVAC system and run it for lesstime when it is on," says Eric Davis, engineering student andthe team's engineering coordinator.The HVAC system includes an efficient heat pump and heatrecovery system, which has a dedicated connection to the PVsystem, to decrease energy losses that occur when invertingthe solar power from direct current (DC) to alternatingcurrent CAC).Solar TechnologiesThe house uses solar water heating and PV panels to producehot water and electricity for the house. A grid-connected,S.6-kW PV system sends excess electricity back to the powergrid. The pa nels are supported on an operable structure thatallows them to be adjusted seasonally following the angle ofth e sun. The solar hot water system includes two collectors.The team worked with Fat Spaniel Technologies to developa home energy monitoring system that includes a live Webinterface to display energy demand and production. Thedisplay, accessible from any Internet connection, becomes atool for both education and increased energy efficiency.Working Together Toward SustainabilityThe team says that working with different students,government staff, and industry professionals has broughta much better understand ing of the "languages" people indifferent disciplines speak.~ Th e U.s.

-102 I UNIVERSITY OF LOUISIANAAT LAFAYETTE In line with Cajun custom, the heart of the house is acovered porch for socializing and entertaining, but thetechnical features of the BeauSoleil porch introduce newflexibility. The IO-by-IO-ft (3.I-by-3.I-m) space betweenthe kitchen and living room is lined by a square track.Transparent sliding doors, part of a specially designedNanaWalll1< system, rotate 360 degrees around the track.The porch can be transformed from an outdoor space intoan interior, conditioned room. Atop the porch is a skylight,partially shaded on the south side by a custom solar waterheating system that is integrated into the translucent roof.Team Web site: www.beausoleilhome.orgCajun Culture Meets Solar Innovation in BeauSoleilWhen the French-speaking Acadians settled in southLouisiana, they brought a vibrant culture and a determinationto adapt their way of life to the warm, humid climate. Thename "Acadian" evolved to "Cajun" over the years, but thecommitment to joie de vivre and the unique regional styleremains intact to this day.Those cultural values are the spirit and inspiration behindBeauSoleil, the house designed and built by the Universityof Louisiana at Lafayette Solar Decathlon 2009 team. Themajority of the team is native to the region and considers theproject deeply personal-and it shows.BeauSoleil, meaning "sunshine" in Cajun French, shares itsname with one of Louisiana's first Cajun settlers- JosephBrousard, nicknamed Beausoleil- as well as a Grammywinningband from south Louisiana. In fact, the BeauSoleilband lent their name to the project, partnered with the teamon promotional efforts (including a mus,ic CD), and willperform a free concert on BeauSoleil's porch on the NationalMall on Friday, Oct. 16 from 5 to 7 p.m.The Heart ofthe MatterBeauSoleil is a hybrid structure in every sense. It combineslong-standing passive solar design concepts with the latestinnovations in energy efficiency and solar energy.Technology Behind the LifestyleThe electricity that powers BeauSoleil comes from a 7.8-kWsystem of PV panels on the south-facing portion of the roofthat is expected to produce a net surplus of electricity forthe competition.BeauSoleil's exterior cladding is a rain-screen system thatallows air to circulate between the siding and the wall,minimizing heat from the sun. Walls consist of 6.5-in(l6.51-cm) SIPs, which provide double the insulationof common stud walls and reinforce the strength of thebuilding. The house's efficient HVAC system includes threeadjustable zones. A dehumidifier controls summer humidity,which is a serious problem in Louisiana.The team developed many of the technical features ofthe house, but the real challenge was seeing the projectthrough to completion. "It's totally eye-opening," says ScottChappuis, an architecture student and a project architect."We started building in January. Since then, I've learned asmuch about how build,ings go together as I learned the wholetime in schooL"The house is reminiscent of a traditional south Louisianahome. In the drier seasons, the north-south orientation takesadvantage of local breezes, and floor-to-ceiling, French-stylewindows maximize ventilation. The windows also providenatural daylighting. Exterior cladding is covered with locallyharvested cypress.

103 I TEAM MISSOURI (MISSOURI UNIVERSITY OF SCIENCE &TECHNOLOGY, UNIVERSITY OF MISSOURI)Team Web site: www.solarhouse.mst.eduShow-Me House-Missouri's FourthSolar Decathlon EntryMembers of the Show-Me House team refer to their projectas a "very Missouri" house. From its long, elegant linesand Missouri oak floors to the reclaimed barn wood in bothits furniture and exterior siding, the structure recalls thelandscape and heritage of the state.Missouri houses are a fixture at Solar Decathlon. MissouriUniversity of Science and Technology (Missouri S&T) hasbeen a competitor in all four Decathlons. For the 2009 event,the school is partnering with the University of Missouri­Columbia (MU) to broaden the team perspective and makethe Show-Me House more representative of the entire state.Nearly Invisible Control SystemThe most innovative feature of the Show-Me House isthe Chameleon Home Automation System, designed bythe team. Through a series of environmental sensors, thesystem activates heating or air conditioning to ensure inccomfort. Chameleon can also control humidity, automatilrun appliances, and turn lights on and off. It can even op'and close windows. Residents program the system with ainterface that is accessible via touch screens throughoutthe house.Effective, Electronic CommunicationBecause the Missouri S&T campus in Rolla is more than100 mi (160.94 km) from MU in Columbia, inter-campuscommunication has general'ly been limited to conferencecalls, e-mails, and document exchanges, but team memb(are quick to point out that logistical complications have ndiminished the Decathlon experience.Lessons Learned, Lessons AppliedThe 2009 Missouri team abandoned the multi-modulehouse concept, as seen in past Solar Decathlons, in favorofa single, easier-to-transport, 15-by-50-ft (4.6-by-15.3-m)module. A hinged roof tops the house. SIPs in both the roofand walls provide an R-40 insulation value.The roof supports an 8-kW PV system. Also atop the roof isan evacuated-tube solar water heating system for a varietyof home uses, including radiant floor heating.Designers used natural wood and white walls to increasethe sense of interior space. "The house itself is very open,"explains Andrew Adams, a civil engineering student atMissouri S&T. "From the entrance, you can see the kitchen,dining, and living rooms." At 375 ft 2 (34.84 m 2 ), the livingroom and kitchen area is the largest in the house. Thebedroom, with 160 fe (14.87 m 2 ), opens onto the house'sexpansive outdoor deck."One of the things I've enjoyed 1110St is taking what I'velearned in the classroom and applying it in the real worlsays Dominic Clucas, an electrical engineering student IMissouri S&T who serves as the team's safety officer. ",some of the friendships we've made. The way we look aeach other and laugh. It's a lot of fun."The house was constructed in Rolla, where the team'sprevious three Solar Decathlon houses are on display incampus Solar Village. After the competition in Washin~D.C., the Show-Me House will be transported back toMissouri S&T and added to the village, where it will befor research projects and student housing._ The U.s.

Active strategies include efficient heating andcooling systems as well as electronically controlledventilation shutters.The south wall of the house has a unique water wallsystem made of specially designed vacuum-formed clearplastic tanks. The tanks act as "heat sinks," storing heatduring the day and deterring it from entering the houseand then releasing it slowly after sundown. The team usesthe evacuated-tube solar water heating system on the roofto heat water using only the sun to relieve some of theelectricity load of the house.Team Web site: www.uasolardecathlon.comSowing the Seeds of SolarIn nature, seedpods protect and nourish seeds as they growinto plants. The University of Arizona's Solar Decathlon 2009team is nurturing a vision for an energy-efficient solar housein line with natural principles and available to all. After thecompetition, the team hopes that the Solar Energy-EfficientDwelling, or SEED [pod] house, can be easily customizedfor different tastes and climates and shipped to any locationwhere eco-minded and cost-conscious buyers want to "plant"it. Because the house is modular, customers can size it tofit their needs. The roof angle of the house is adjustable andadapts to a spectrum of solar angles at locations around theworld to maximize the efficiency of the solar electric systems.Matt Gindlesparger, a faculty advisor from the Schoolof Architecture and team project manager, says that thehouse incorporates both passive (non-mechanical) andactive (mechanical) strategies.

Rainwater isalso collected and stored in tanks for use in the greenhouseand for landscaping. Vegetation shades the south wall duringthe hottest time of the year and can be cut back to takeadvantage of the sun's heat during winter. The large outdoordeck is made of a permeable material that allows water to runthrough it to the ground below.Working With NatureThe team achieved energy efficiency and comfort in theSEED [pod] by looking first to natural daylighting and otherpassive cooling and heating strategies- such as naturalventilation, strategic insulation placement, and shading ofThe 8.6-kW PV system incorporates innovative panels,called "bifacial" solar panels, that collect solar energy ti·omboth sides of the panels to generate electricity. Used inapplications such as carports and shade areas, these panelsallow 15% of the daylight to pass through them. A cavityunderneath the panels allows for ventilation and up to30% more efficient panel operation through the collectionof ambient light that has passed through the panel or isreflected off surrounding surfaces.A Smart SEED [pod]The house features an intell igent bui Iding system thatmonitors energy production and use. Alarms alert occupantswhen the PV system is not performing properly and canmake suggestions when there is surplus electricity available.Response from the local community is encouraging.

lOS I RIcE UNIVERSITY Team Web site: www.ricesolardecathlon.orgHouston, We Have aHouse:Rice University's ZEROW HOUSEFrom Africa to the Caribbean to the southern United States,"shotgun" houses have been home to low- and middleincomefamilies for centuries. Building on this tradition,the Rice team designed and built the ZEROW HOUSE,a modern interpretation of a shotgun house in a row housecommunity that incorporates affordable, practical,energy-saving solutions.Lots of Light Enlarges the HouseThe house receives the majority of its natural lighting fromthe "light core," a glass-encased volume inserted into thehouse that acts as an exterior extension of the living space. A"light cove" provides a wash of light along one wall achievecwith state-of-the-art LED strips attached to the walls andceilings. David Dewane, the team architecture lead, says thai"great integration between architecture and engineering"makes the house feel much larger than its 520 ftl (48.31 m 2 )of interior space.The community seems to agree. People who have touredthe house say it doesn't feel small and that they'd like to livein it. The team met the Housing and Urban Developmentguidelines of affordability to those witb 80% of the area'smedian income.Instead of building a house just for the competition, the teamdesigned a home they could give back to the community. Theteam has already negotiated an agreement with Project RowHouses, a neighborhood-based art and cultural organization,to give the ZEROW HOUSE a permanent home in Houston'sThird Ward after the competition.Affordable Energy EfficiencyThe team's goal was to build a practical house thatdemonstrates affordability and energy efficiency usingreadily available technologies. According to Danny Samuels,Rice team faculty advisor: "We always opted for making itpractical. We saw it truly as a market demonstration of whatis feasible and possible, to show that an affordable house canbe energy-efficient and available to basically everybody."Architecture student Rebecca Sibley adds that the teamchose appliances that minimize electricity use. The house'stotal lighting fixture energy use is about 250 W- less thanthree standard, 100-W light bulbs. And at 4.2 kW, the house'sPV system is relatively small compared with other SolarDecathlon houses'. According to the team's cornmunicationslead, Allison Elliott: "When people come to the NationalMall, they can see you don't need a million solar panels. Youcan do a lot with a smaller array."An Enthusiastic CommunityTeam members say they're finding the enthusiasticcommunity involvement particulady inspirational. They'vehad no trouble recruiting volunteers. Contractors havedonated time and materials, and union apprentices pitchedin by installing plumbing and electrical systems. Althoughtheir fundraising efforts have ranged from "exciting" to"heartbreaking," the team hit a high point when one localstructural engineer talked colleagues into grouping smalldonations into a pool, raising $15 ,000. According to Dewan" It helped that the affordability and practicality of our desigkept costs low."The team is excited about the Solar Decathlon 2009competition, but it's also looking fOr\\/ard to the daywhen it brings the house back to the mission control centerof Houston.__ Th e u.s.

III106 I TEAM ALBERTA (UNIVERSI1Y OF CALGARY, SAlT POLYTECHNIC,ALBERTA COLLEGE OF ART + DESIGN, MOUNT ROYAL COLLEGE)AWhole Lot of LivingThe Team Alberta entry packs a whole lot of living- andworking and playing- into its limited space. The houseincludes an open, vaulted-ceiling living room and kitchenarea, a stone-clad core area for the bathroom and mechanicalsystems, a bedroom and home office space, a rooftop deck, ahallway dividing the bedroom and home office from the morepublic areas of the house, and even a yoga space.Nurturing an IdeaFourth-year University of Calgary business student MarkBlackwell describes the Solar Decathlon experience ashaving: "been my life. It's like raising a baby as a family."This particular family is highly extended, including studentsfrom four schools: SAlT Polytechnic (Southern AlbertaInstitute of Technology), Mount Royal College, AlbertaCollege of Art + Design, and the University of Calgary.Team member Mi ke Gestwick reiterates that students at eachof the schools nurtured this "baby." "The project really hasbeen 100% student led," he says. "The faculty has been veryhands-off." That is, if you don't count Calgary architecturegraduate student David Silburn, who says, "All the work wehave been willing to put into the house shows the power ofthe project." Silburn has already parlayed his Solar Decathlonexperience into a position as a sustainable architecturefaculty advisor at SAlT Polytechnic.High Tech- and NorthwoodsUniversity of Calgary environmental design graduate studentMatt Beck says the Team Alberta house is intended " to showoff a different side of Alberta- ingenuity, efficiency, andsolar technology." And there is plenty of that in the house,with a programmable logic controller that automaticallyadjusts blinds, a solar-assisted GSHP, an energy-recoveryventilator, and LED lighting (which the team developedbecause commercial automated dimmable LEOs were notquite availab'le at the time, although they are now). Thehouse even includes a "call for service" function , if therewere a problem. The audio system isolates itself fromthe house's AC power when it is fully charged and runson higher-quality, lower-draw DC power. The house isalso equipped with a 7.6-kW PV system. The TV, whichis integrated into the kitchen island, is LED backlit forlow power draw. Controls and instrumentation were animportant emphasis of the Team Alberta effort.At the same time, the house is very much "Northwoods."" Historic post and beam" or "Western Canadian timberframe" in style, the house showcases local stone and woodand was intended to feature local suppliers. In addition toproviding materials, local companies responded generouslyto general fundraising, which, like the entire project, wastotally a student effort that went much better than expected.Premium MarketThe Team Alberta house was designed with young, valuedrivenresidents in mind. The combination of sophisticatedutility and entertainment systems, traditional exterior andmodern interior styles, and the balance of private spacessuch as the home office and yoga room with public spacessuch as the living area and rooftop deck should serve thatmarket well. The house features lots of "extra" touches suchas attractive stone finishes, special-effect lighting (some ofwhich highlights integrated artwork), Web-enabled controlof almost everything, and even cutlery designed to matchthe decor. In keeping with the house's private and publicsplit, an expandable kitchen counter and other features aredesigned for entertaining large groups.

107 I TEAM ONTARIO/Be (UNIVERSI1Y OF WATERlOO, RYERSON UNIVERSITY, SIMON FRASER UNIVERSITY) Team Web site: for the NorthThe objective of Team Ontario/BC was to build a houseap'propriate for the Canadian climate. Toktam Saeid,a mechanical engineering master's student at RyersonUniversity in Toronto, describes the challenge: "Because weare a Canadian team, we wanted to design for the north andshow how to make things work in the north. We thereforehave to deal with extremely cold winters and hot andhumid summers."Designing for northern latitudes also meant a differentapproach to passive solar heating and solar electricity. Theteam could not count on much power from rooftop panels inthe winter but could make good use of low-angle sunlightfor much of the year. Thus the south, east, and west sidesof North House have floor-to-ceiling windows framedby vertical solar panels to help with winter heating. Howwill this northern design work in Washington, D.C.? "Noproblem. October in D.C. fits what we are designing for insummer months," says Saeid.Looking to the FutureMaun Demchenko, a University of Waterloo graduatearchitecture student, joined the team in January but hasbeen working on it full time- and then some-ever since."The interdisciplinary work has been great. We're getting anamazing view to what the future will be like for all of us"Demchenko says.'Teammate Johnny Rodgers, a Master of Interactive Artsand Technology student from Simon Fraser Universityin Vancouver, British Columbia, says: "The energy andenvironment are very important to me. We are all veryexcited to go to Washington. It will be really neat to see whatother teams come up with." Rodgers' specialty for the projectis developing a computer "living interface system" for NorthHouse. Whereas the building mechanical systems will beab te to operate automatically, the living interface is designedto give the residents as much feedback as possible.Compact and MobileIn addition to design that capitalizes on low-angle sunlightand visualizes energy use, the house employs functionalfurniture that stores away when not needed. The bed retractsto the ceiling, the home entertainment system occupiesminimum space, and the entire work space becomes mobileto suit user needs and maximize comfort. In addition. thenorth side of the house, which houses all the mechanicalsystems, is clad with a "Swiss Army wall" that is packedwith hooks, storage nooks, and as many functionsas possible.Connecting With the OutdoorsWhereas the team describes the house as "minimalcontemporary" and "performance-driven in style," it wasalso designed to be open, light, and airy. Its floor-to-ceilingwindows on three sides not only let in warming wintersunlight but also build a strong connection to the outdoors,Dynamic shading on the exterior of those windows can keeout solar heat in the summer or retain heat at night andin the winter.Other incorporated technologies are an 11.9-kW PV systemthat produces electricity to power the house; sah-hydrate, aphase-change material, in the floor; and cascading storagetanks integrated with evacuated-tube solar collectors. Thehouse also incorporates a heat pump that increases the tanktemperatures to provide hot water for heating and houseneeds and a second heat pump, used for cooling, that is tiedto a heat-sink "pond" under the deck.The U.s.

Desiccant systems remove humidity from the air.Because it is easier to cool dry air than humid air, the airconditioner operates more efficiently.Generating ElectricityTwo kinds of PY panels make up the 8.9-kW system. Themain system consists of typical crystalline silicon as wellas an integrated thin-film layer that is estimated to produceelectricity more efficiently than similar systems. A smallerarray is made of custom thin-film modules integrated intothe southern and eastern window louvers as well as into atracking louver array on the roof.Team Web site: www.solard.iastate.eduSolar and Sustainability for SeniorsInterlock House offers seniors a new option for livingindependently: in a sustainable house as a contributing partof a community. It will become increasingly important toconsider the needs of seniors who want to "age in place"because seniors will account for about 20% of the populationin 20 years.Interlock House meets all regulations for accessibility underthe 1990 Americans With Disabilities Act. The house is alsodesigned to increase the density of existing communitiesby incorporating seniors into them instead of taking overundeveloped land. Peter Mauro, the team's architectureproject manager, says, "Interlock House is designed to helpretirees move onto existing lots, perhaps with their families,interlocking with existing sewer and water systems and socialnetworks." The house's ability to give electricity back to thegrid is an added benefit.Form and FunctionThe "heart" of the house is an enclosed sun porch on thesouth, where occupants can relax during all seasons. Thesun porch is surrounded by a specially designed, ENERGYSTAR

109 I PENN STATE Team Web site: www.naturaljilsion.orgFusing Form and Function Through TeamworkNatural Fusion is the holistic integration ofelements.That's the theme for the Penn State Solar Decathlon 2009house. As the team members began working together, theyfound that reaching their goal required another principle:interdependence. To reach true integration, it was vitalthat the students exchange knowledge among theirmultiple disciplines.Alyce DiLauro, Penn State's events coordinator, says: "Ialways wanted to make a difference through volunteering.I used to do everything myselfjust to make sure thingsgot done. But, in the Solar Decathlon, you have to workas a team."Penn State's student team leader, Kyle Macht, concurs. Aveteran of Solar Decathlon 2007, he found himself in a newrole during the 2009 event. "In the 2007 competition, I wasthe jack-of-all-trades," he says. "Now, I'm leading the team.It 's all about collaboration so we can integrate our visionand ideals."All that collaboration has paid off. The Penn Stateteam has managed to meld nature-inspired aestheticswith functionality.Using the Power of the SunPenn State is employing a new technology called GreenRoof Integrated Photovoltaics. This approach combines asolar electric system with plants that help remove heat fromthe roof. The team is also using a new type of cylindrical,thin-film PV system designed to maximize sunlightcollection throughout the day. The S.I-kW system generateselectricity to power the house.The team put a lot of effort into passive solar anddaylighting design. Clerestory windows, tri-fold doors, andsolar water heating panels that function without pumpsTh e U.s. Department of Energy Solar Decat hlon 2009are all found on the southern fayade. The windows anddoors provide ample daylight throughout the year. When ttdoors are open to the deck, the living space expands to theoutdoors. The vertical position of the solar panels mimics 1design of the tri-fold doors.A southern overhang blocks the sun's heat in the summerand allows it in during winter. An awning has tracking fin!coated in PV material that align themselves for maximumexposure to the sun, thus generating more power.Buffering Temperature ChangesNatural Fusion uses the concept of thermal mass toregulate indoor temperatures and reduce the house's energrequirements. A \-vater bladder system embedded in the floand phase-change material in the walls and ceiling store h(during the day and emit heat at night. The phase-changematerial converts from solid to liquid when the temperaturrises and from liquid to solid as the temperature decreases .The water bladder system can be emptied to reduce thehouse's weight for transport, which, in turn, requiresless fuel.Making It Feel Like HomeLike the exterior, the kitchen features a wall composed ofwood slats that can be used like a pegboard to hang shelvepots, pans, spices, planters, or a combination of these. ThePenn State team populated this wall with lush herbs thatprovide fresh seasoning for cooking and a pleasing, naturvisual element for residents.Natural and recycled materials are used throughout thehouse, including sustainably harvested lumber, reclaimedchalkboards and hardwood flooring, bio-based foams, an(jpaint containing no volatile organic chemicals.The team has created an impressive house, but theexperience each team member has gained may be itsbiggest legacy.

-110 I TEAM SPAIN (UNIVERS I DAD POLITECNlCA DE MADRID)The Black and White House features a 14.9-kW PV systemto power the house and a solar water heating system forradiant floor heating and domestic hot water. An electricGSHP, powered by the PV system, provides supplementalheat. When the house ,is installed permanently, the heatpump will save energy by tapping the thermal mass ofmoderate-temperature, ground-source water pipes. On theNational Mall, a bladder with 8 111" of water will providethis thermal mass. Overall, the need for supplementalheating is reduced by passive solar heating from theconservatory and phase-change material in the ceiling andinterior walls.Team Web site: www.solardecathlon.upm.esSiga el Sol-Follow the SunMake a squat pyramid of glass-invert it base up, and installboth solar electric panels and solar heating water collectorsin the upward-facing base. Next, set the tip of the pyramidon a ball-and-socket mechanism pivoted by a solar trackingsystem like a very slowly spinning or tilting toy top. Put thison top of a house, and you have the essence of the uniqueTeam Spain Solar Decathlon 2009 entry.Great Art Studio LightArchitecture student and lighting specialist for the projectVictor Garcia explains that because the sides of the pyramidare reflective, the house is filled with northern light passingthrough skylights in the actual roof, plus light passing downthrough the open tip of the pyramid. Louvers on the sides ofthe house are also automated to let in natural light withoutglare or unwanted solar heat-except for a glass conservatoryon the southwest corner that helps heat the house whenneeded. Daylighting is supplemented by highly efficient LEDlights, many placed in the skylights. Garcia says, " Energyis what I'm here for," and because of his Solar Decathlonexperience, he has chosen lighting design for amaster's program.First of Its KindLicensed architect team member Jaime Promewongse saysthe house's solar-tracking top roof may be the first of itskind. The university has filed for a patent on the ball-andsocket,central-pivot system that makes it possible. Therooftop's PV panels, solar thermal collectors, and glasswalls provide the house's solar energy.David Sigilenza says that making the house highlymodular was also a primary objective. In addition tomaking it easy to ship to the Solar Decathlon, this makesthe house more marketable, allowing easy addition of extrarooms, addition of the rooftop to existing homes, and saleof the house as a "portable house" under Spanish law.The portability might also come in handy for future useof the house, one option for which is a 2010 sustainablearchitecture exposition in Shanghai, China.Black and White HouseJust as the pyramid rooftop and louvers automaticallyfollow the sun, the house will follow the sun by crossing theAtlantic Ocean from Spain to the United States. Graduatingarchitecture student Irene Garrido says that the team refers tothe house as the "black and white house- but with an orangetouch of color," because it meets the y in and yang of highefficiency and comfortable living.

The house also captures the beautyand spirit of Kentucky through the photographic images oflandscapes integrated into screens on its exterior walls, thesky-viewing ribbon of continuous clerestory windows aroundthe top of each wall, and a deck that blurs indoor and outdoorspaces alongside a selection of native plants.A Unique Relationship With Light and SpaceThe team's mantra, " Iive.light," calls first on passivestrategies to lower electrical load and then uses simple,smart, and active solutions to minimize the house's carbonfootprint. Integrated lighting strategies balance natural andartificial I ight sources through an adaptive and controllablesystem to not only harness the sun's energy via PV cells andsolar thermal collectors but also channel light to illuminatean articulated core that anchors the house.HVAC SystemThe heating and ventilation system uses a high-efficiency,reverse-cycle chiller coupled with a small thermal storagetank to provide hot water for floor heating and cold waterfor air conditioning and dehumidification. The house isseparated into three radiant heating zones and two coolingzones based on occupancy and use.

113 I TEAM BOSTON (BOSTON ARCHITECTURAL COLLEGE, TUFTS UNIVERSITY), Team Web site: www.livecurio.usEmpowering Homeowners To Live SustainablyCurio.House was designed by Team Boston to triggercuriosity about 110w well-designed homes can help saveenergy and money and improve the health of the planet.The team, a collaboration between Boston ArchitecturalCollege and Tufts University, has satisfied that curi10sity byincorporating an energy-monitoring system into its house.This system provides real-time feedback so homeowners canknow exactly how much energy they are using, when theyare using it, and how to adjust their habits to reduce theirenergy bills and environmental impact. The system employsa Web-based display that can be accessed from a homecomputer, Internet connection, or iPhone. In this house,designed to perform during the frigid Boston winters,energy will come mostly from the sun and be conserveda variety of ways.Solar Electric Panels and Micro-InvertersThe house employs a 6.4-kW PY system to generateelectricity. These panels connect to inverters that convertthe DC to AC so energy can be used in the house and fedinto the electricity grid. Instead of a centralized inverterconfiguration, with many panels feeding into a single largeinverter, Team Boston is using micro-inverters that attach toeach PY panel. This method gives the homeowner flexibility,allowing for easy repair, replacement, modification, andexpansion of the system.Solar Water Heating SystemThe house uses a flat-plate system to provide most of its hotwater. Tubes within the collectors are filled with liquid thatabsorbs heat from the sun. To avoid freezing in the subzerotemperatures of Boston winters, the liquid contains anorganic-based glycol. The heated liquid is then transportedto a heat exchanger that transfers the heat to thehousehold water.Daylighting and Solar Heat RetentionDaylight streams through the expansive windows on thenorth and south sides and reduces the need to use theefficient fixtures, fitted with LEDs and CFLs. In the sumexterior roller shades and an overhang on the south roofblock the sun and help keep the house cool. In the winter,southern "heat glass" windows capture the heat to providewarmth throughout the night. Polycarbonate panels on thenorth window frames decrease heat loss and help blockwinter winds.Appealing to a Wide MarketCurio.House aims to attract homebuyers with varyingdegrees of technical expertise. As Boston ArchitecturalCollege student and Project Manager Colin Booth says,grandma might not want to see all the data available in themonitoring system, but it could still allow her to set hertargets for consumption, rather than being told how to live."Others, however, may dig deeper into the monitoring datathey can make more refined adjustments, such as expandia solar array or using the exterior window shading atdifferent times of day." It's about information, not about being controlled, andbecoming comfortable interacting with the technology,"Booth says. "We believe that this is a crucial part ofsustainable living-getting average people to be curiollsand engaged."The U.S. Department of Energy Solar Decathlon 2009

114 I TEAM GERMANY (TECHNISCHE UNIVERSITAT DARMSTADT) Living in Maximum Solar ArchitectureThe Team Germany house epitomizes the architecturalsingle-room concept. Other than the bathroom and asmall, open, second-level gallery above it, the house is asingle, multifunctional room. Every window affects thelighting for the whole house, and nonreflective materialsand controllable LED lighting provide a warm atmosphere.Custom equipment and furniture maximize the utility of theliving space, and aU of the furniture, including the bed andentire kitchen, can be stored or serves mUltiple functions.Sustainably EncasedTeam Germany started with a "focus on the fac;:ade," creatinga house that is essentially a two-story cube. The surface iscovered with solar cells: an 11 .1-kW PY system made of 40single-crystal silicon solar panels on the roof and about 250thin-film copper indium gallium diselenide solar panels onthe sides that is expected to produce an incredible 200% ofthe energy needed by the house. The side panels are slightlyless efficient than the silicon panels but will perform betterin cloudy weather. The fac;:ade is made of highly insulating,custom vacuum insulation panels plus phase-change materialin the drywall to maintain comfortable temperatures andautomated louver-covered windows to control passivesolar gain.Standing on the Shoulders of GiantsThe 2009 German team is relatively small with only 24students, mostly architects. But Sardika Meyer relates howmany others took part. "Even my boyfriend, all the familiesand friends got involved," she says. "We had so muchsupport. It was really incredible." And although the teammembers are all new, several people from the 2007 first-placeteam are still around. "They are like big brothers, lookingover our shoulders, teasing us," says Franziska Hartmann.The team is also grateful for help from the university andmany equipment manufacturers.Evolution of an Idea"In the beginning, there were 16 individuals with 16 ideasof the 2009 house," explains Annike Gaigl. "We had aninternal competition and now are building only this onehouse. It is absolutely amazing having the chance to realizeour own vision, from planning up to the last screw." PatrickTauchert says that that evolution was a big part of thelearning experience for him. "We started with a vision buthad to consider both German and American building codesas well as Decathlon rules as plans became more definite,"he says. "We also had to make cost and material availabilitycompromises, such as giving up on prototype flexiblethin-film photovoltaic cells that we really wanted."With its multiple-use possibilities, but limited private space,this "aesthetic solar architecture" is intended for openmindedyoung couples, singles workil1g from home, andpeople who travel a lot.Technologies and FeaturesThe Team Germany house features an electric air-sourceheat pump system that provides all of the house's heatingand ventilation needs, most of its cooling needs, anddomestic hot water. This system can be upgraded to aground-source system with permanent installation. Thehouse also features phase-change material in the wallsand ceiling that reduces heating and cooling needs and anautomated operation system that controls the heat pump,window louvers, lighting, multimedia entertainment system,and appliances.Team Germany aims to demonstrate innovative sustainabledesign and make it an object of discussion. Its architecturalvision offers an alternate lifestyle that introduces theconcepts of energy efficiency and sustainability assubstantial elements of everyday life.-

115 I VIRGINIA TECH Team Web site: Ideas With an International FocusVirginia Tech is the only u.s. team participating in bothSolar Decathlon 2009 and Solar Decathlon Europe 2010. Theteam members are excited to compete in both competitions,though they feel some added pressure going up against 40student teams from around the world. They are confidentthat the Lumenhaus will score both during and after thecompetition-bringing new ways ofiiving, designing, andworking to team members and communities near and far.Lumenhaus Delivers a Brighter DayThe central theme of Lumenhaus is light. A pavilion designfeatures sliding north and south walls made of glass. Theglass walls can be completely opened to allow air as well aslight into the house and also can expand the footprint of thehouse onto the decking and outdoor space. Skylights in thebathroom bring natural light into the farthest interior spacesand allow for a translucent membrane ceiling. The lightingsystem features dimmable fluorescent fixtures with daylightsensoring that allows diffuse light to filter throughout thehouse to maintain consistent light levels when the houseis occupied.Responsive Architecture"We're really focusing on bringing the outside in and viceversa and on responsive architecture," architecture studentKristin Washco says. Two sets of movable wall systems areautomatically controlled by the house computer based onweather conditions, or they can be operated using an iPhone.Responsive architecture features include the ability tooperate the heating, cooling, lighting, and sun shading witha computer, which receives environmental condition datafrom sensors inside the house and a weather stationoutside the house.Borrowing Power From the EarthA concrete floor- rare in Solar Decathlon houses- is partof a strategy to provide passive, radiant heating. The floorfunctions as thermal mass that is heated by the sun anda radiant hot water system of piping underneath the slab.Keeping sun off the floor in summer is also acooling strategy.Water is heated using a geothermal loop coupled withefficient water-to-water and water-to-air heat pumps. Thegeothermwl system consists of a series of pipes in the earththat keep water at a fairly consistent temperaturethe year-efficiently delivering heated water in the winterand cooled water in the summer. Because it is not possibleto drill a SOO-ft (lS2.4-m) well on the National Mall, asimulated geothermal loop system has been constructedconsists of a 1,000-gallon (3,78S.4-liter) water tank coupledwith a waterfall and evaporator system.Making Energy From the SunThe Lumenhaus 9-kW PV system is also unique.Monocrystalline silicon wafers are mounted betweentransparent glass plates, so some sunlight passes throughthe PV panel, reflects off the roof, and bounces back up tothe back side of the wafer, generating additional electricity.The team estimates that these panels will produce twice theenergy needed to power their energy-efficient house so tcan score high in the Net Metering contest.From Campus to Real WorldLike many teams, Virginia Tech is discovering thatthe biggest 'learning experiences during the project aredeveloping the skills to work with team members fromdifferent disciplines and seeing how a project goes from adesign on paper to a real-world working prototype.The U.S .

SIPs were installed in both the roof and the flooring.The module walls facing the courtyard are a transparentNanaWall system that provides insulation while openingthe rooms to the outdoors, increases natural light, and helpsprotect the interior from overheating.Team Web site: www.clIsd.comell.eduArchitecture and Engineering-Collaborating for ChangeFor Cornell's third consecutive Solar Decathlon competition,the 2009 team wanted to do something bold. They decidedto make their house and their project unique at every step,starting with a juried competition to select the design."Our initial goal was to move away from the 'conventional'houses that are common in the Solar Decathlon," says IrinaChernyakova, an architecture student and one of II teamleaders. With 15 design submissions to choose from, the teamopted tor an approach that provides the eye-catching lookthey wanted and incorporates the high-tech, energy-efficientfeatures that make a 21 st-century house a home.Interdisciplinary collaboration, especially betweenarchitecture and engineering, characterizes virtually all theteam's choices. "It's a team philosophy," says Chris Werner,an architecture student and team leader. "The challenges toengineering are unique," adds Myra Wong, a mechanicalengineering student and team leader. "We really try to look atthe big picture."Looking Back to the FutureThe collaborative result is the Silo House, which consistsof three separate "plug and play" cylindrical modules thatinterconnect to form a single structure. All the modules openonto a common courtyard. Reflecting the shape of the grainsilos that dot the rolling hills of upstate New York, the houseand its landscape of carefully selected grasses present whatthe team calls a "post-agrarian look," a reminder ofvanishing farmland.Each silo is 16 ft (4.9 m) in diameter, with about 130 ft2(12.1 m 2 ) of floor space. The three modules- kitchen, livingroom, and bedroom- are joined on the south side, leavingthe north side open. The exterior is covered with COR-TEN:lI\a corrugated steel cladding that acts as a weather barrier. Asthe outer layer oxidizes, it gradually loses its original sheenand takes on a rusty, ruddy look .More and Less, Under One RoofThe house is designed and equipped to maximize spaceand minimize energy use without sacrificing comfort.The kitchen, which can accommodate up to eight people,features an island with a countertop that slides back to revealENERGY STAR appliances.

117 I UNIVERSIDAD DE PUERTO RIco Miranda Palacios adds that Puerto Rico is currently workilon adopting a more stringent energy code, and the team'shouse "could be a showcase project for this effort."Team Web site: wl;1!w.casasolar.uprrp.eduAModel for the CaribbeanThe objective of the 2009 University of Puerto Rico teamwas to bu i ld a house that could serve as a model energyefficienthome for the Caribbean. The Universidad dePuerto Rico is one of only two schools to enter all fourSolar Decathlons, but a key inheritance from that historywas a negative comment. In 2007, a non-Decathlon studentobserved: "That doesn't look like the Caribbean. It looks tothe inside, not the outside."Billed as CASH-Caribbean Affordable Solar House-theL-shaped house clearly looks to the outside and responds tothe opportunities and challenges of the Caribbean climate.The two legs of the L are connected by an outdoor patio. Oneis enclosed with special screens to allow occupants to lookout and cooling breezes to pass through but block nearly 90%of the sun's rays. The other mechanically conditioned leguses the same screens but has s'liding glass doors that can beclosed off when conditions warrant.Building on the Past ...Team member Zoe Galan Comas, a recent graduate of theuniversity's Master of Architecture program, points out thatwith all its high-tech mechanical systems and passive solardesign, the 2009 hOllse design builds on the distant as wellas recent past. "The basic approach is Caribbean Vernaculara floating style that originated with early Puerto Rican 'buildings whose raised floors keep out pests, alleviate highhumidity levels, and encourage natural ventilation,"says Comas.... For Homes ofTomorrowTeammate David Ramirez, another recent graduate fromthe master's program, underscores the importance that anenergy-efficient home model could have in Puerto Rico."Most people I know have absolutely no idea how the designof a house can save energy," he says. Faculty Advisor SoniaAssisting NatureTechnological highlights of CASH include a IOA-kWcrystalline silicon PV system that generates electricity, anevacuated-tube solar water heating system that providesdomestic hot water, and a radiant ceiling system ofpiped water that provides cooling and heating. An extradehumidifier addresses humidity- the biggest cooUngchallenge in the Caribbean. A small conventional airconditioner, with sensors that turn it off when doors areopen, provides mechanical cooling. The house also feature:supplemental LED lighting.looking to the OutsideNatural lighting and cross-breeze ventilation through thescreens are central to the house's passive energy features, tit also has tight-sealing, locally made, radiant film-glazedwindows and closed-cell, foam-insulated walls of wood.Generous use of wood- particularly reclaimed- contributto the Caribbean feel of the house.

118 I UNIVERSITY OF MINNESOTA The 8.2-kW PY system consists of conventional roofmountedPY panels that produce most of the electricityand a translucent bi-facial PY product- some light passesthrough and is reflected back to the underside to alsogenerate electricity. Designed to maximize production, thesesystems feature different inverters (to change DC to AC) forthe different types of PY and different orientations.Sunshine on aTight Lighting BudgetUsing a design that maximizes the use of natural light andreduces the energy spent on electric lighting, the teamcalculated that it could stick to a lighting budget of 500 Wof electric light for the entire house. Electric lights createdifferent effects in various spaces, with the most dynamiclighting in the kitchen at the east end of the house and themost static lighting in the living room at the west end, whereoccupants may need to control light carefully.Team Web site: www.solardecathlon.umn.eduANew Icon for Solar HomesThe University of Minnesota's Solar Decathlon 2009 teamhas created a solar house with an iconic new look designed tomeet the challenges of heat loss in an extremely cold climate.The gabled roofline, resembling a "real" house, is one of thefeatures designed to appeal to a large group of eco-consciousconsumers who might not want to live in a "futuristic"house. By shifting the roofline slightly, the team has takentraditional design and modified it to create easy access forsolar energy collection.The Heat Loss ChallengeThe team set out to design a house that uses as much "free"heating from passive solar sources as possible and alsocreates a tight envelope that keeps heat from escaping.Large areas of insulated glass on the south side of the housebring the sun's heat into the space. The offset gable of theroofline and the south wall are used as solar collectors,generating hot water and electricity. Windows have specialinsulating shades and are triple-paned, low-e, and filled withgas. The wall and roof insulation have values of R-50 andR-70, respectively. Windows on the east and west walls aremade of electrochromic glass, which has adjustable tint tokeep out much of the sun's heat in the summer.Cold Weather, Hot SolarWhen passive solar heating isn't enough, the house featuresa system that circulates hot water under the floor to produceradiant heat. Flat-plate solar collectors on the roof heatwater for the kitchen and bath in addition to heating thehouse. In the summer, the solar hot water system rechargesan innovative desiccant, or drying, system that efficientlymaintains humidity and comfort levels."We're using new light-emitting diode fixtures from locallighting designers, with warm color light that contributesto the familiar feel of home," says Joe Messier, a master'sstudent in the College of Design and the commissioningteam leader.Not Your Average Competition HouseQuinnell says that the team has never forgotten that they'rereally designing this house for consumers, who might bewilling to make lifestyle changes or buy different products ifthey think it's easy and comfortable."Looking at previous years' houses, they were 'competitionhouses,'" Quinnell says. "Ours is meant to be one thatconsumers and D.C. visitors will be able to identify with,one that encourages market transformation."-

119 I TEAM CALIFORNIA (SANTA CLARA UNIVERSITY, CALIFORNIA COLLEGE OF THE ARTS) process was trying to connect the indoors with the outdoorsboth visually through the windows and functionally withhouse layout," says Sennott.Team Web site: www.refracthouse.comCalifornia LivingSunny, quick-paced, outdoor. These aspects of the Californialifestyle guided the design and construction ofTeamCalifornia's Refract House. "It really is an outdoor-indoorhouse, and every room has very large windows," says SantaClara University Engineering Team Leader Timothy Sennott."We have worked really hard to engineer something that isluxurious and functional."Refract House takes full advantage of the sunny Californiaclimate. The passive solar design virtually el iminates theneed for heating. Cooling and heating are both handledby a highly efficient, reversible air-to-water heat pump.Radiant heating and cooling are also employed, as is smartventilation and heat recovery. Intelligent control of windowsand external blinds maximizes passive heating and cooling.An unbroken plane of PV panels on the roof provideselectricity for the systems, including a solar water heatingsystem. The PV system is 8.1 kW.Designed with busy occupants in mind, Refract Housefeatures built-in furniture and a low-maintenance interior.State-of-the art appliances conserve energy while providinga well-appointed environment. Outside, a seasonal pondstores rainwater as well as greywater from the house that haspassed through a multi-stage biofilter. Fluctuating with theseasons, the pond will help keep the landscape green.Design ProcessAfter reviewing comments from the 2007 designcompeti~ion, Santa Clara University decided to partner withthe California College of the Arts to integrate design andtechnology into a beautiful, functional house. A CaliforniaCollege of the Arts Solar Decathlon Design Studio generated16 house designs. The chosen design went through manychanges as the architecture and engineering students madecompromises to reach their goals. "A huge part of the designIn another design choice, the roof is cut at a different anglefrom the house to hide the technologies. "The big thingwe were trying to do with the house is to hide the energysystem," says Sennott. "We 'vvant to make the energy sytransparent to the homeowner."Managing Energy ConsumptionThe 2000-2001 California energy crisis impressed theteam with the need to manage the daily timing of energyconsumption. A programmable controller turns applianceson and off throughout the day. "The idea is to empowerthe homeowner to control what is being used and whenby making them aware and giving them direct controlover things like lighting and entertainment circuits," saysSennott. The sophisticated controls and monitoring systemwill display the house's performance in real-time. A specialiPhone application allows homeowners to control systemseven when they are not home.Information for VisitorsThe team wants visitors to learn about things they canin their own homes. The team will use interactive technolto stir interest and educate visitors while they're waiting toenter Refract House. Information panels pose questionsthe technologies of the house. Guests can text a code ora barcode with their phones. The answers as well as moreinformation are sent directly to their devices. These visitorswill leave having gained valuable and applicable renewableenergy knowledge.Th e U.S. Department of Energy Solar Decathlon 2009

120 I UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN with a unique heat pump that helps condition the interior.The warm or cool air is blown very gently through the houseusing very little energy.Sustainable Materials"The siding was pulled from my grandparents' barn innorthern Illinois," says Greenlee. "They sold the farm fordevelopment, and we harvested the barn wood, which waswell over 100 years old." Summer shade panels slide likebarn doors in tracks along the south side of the house, andthe decking material was salvaged from deconstruction ofan old grain elevator.Team Web site: www.solardecathlol1.uillc.eduOld Is New AgainWhat has 100-year-old wood on the outside, the neweststructural bamboo on the inside, and can be heated with asingle hair dryer? If you guessed the University of lllinoisGable Home, you chose a house that melds a traditional lookwith state-of-the art energy performance.Using passive solar design, the team optimized windows,insulation, and roofing material for energy efficiency andsolar gain on sunny winter days while keeping the sun's heatout during the summer. The Passive House Institute U.S. inUrbana, Illinois, will certify Gable Home as using 90% lessenergy than typical construction.Gable Home also produces the energy it needs 'within itstraditional design. Rather than having a single flat roof facingsouth for maximum installation of solar panels, the gabledesign presents only half the roofto the south. This areaaccommodates the 9-kW PV system. "We hope this provesthat solar panels are efficient enough to generate necessaryelectricity and, when combined with different disciplines,will maximize energy efficiency," says student Joe Simon.Technology DetailsOne of the newest technologies in the Gable Home is bamboolaminate board that substitutes for wooden studs in the walls.Developed by a company working with the University ofIllinois, this product is appealing because bamboo growsmuch faster than trees, has stronger material properties,and is resistant to thermal expansion. " Before we coulduse the Lamboo, though, we had to understand its materialproperties," says architecture student Camden Greenlee."So the company conducted structural tests to prove that thematerial could meet our needs."Making a DifferenceTo reach consumers, the team is working with a builderof modular homes to make this more than a one-of-akindproject. "A modular home builder can move aboutone modular house off the assembly line every day," saysstudent Ryan Abendroth. "This kind of production of netzerohomes is important when you talk about really pushingthe green idea. One house doesn't matter so much, butmultiple houses start to add up.""In this project, we see how our design choices in thebeginning affect the building's actual outcome," saysAbendroth. "Then, because we will be monitoring thisbuilding and using it in the competition, we will see howthat outcome works over time. Often, architects don't get thefeedback to see how their choices actually influenced thebuilding. That is one of the most important experiences weget out of the Solar Decathlon.""1 1.1 \'. ,> 11\ IIBecause the Gable Home is so well insulated and resistant totemperature swings, it requires only a small system to controlheating, cooling, ventilation, and dehumidification.
