a strategic program to developbuilding technologies that use theleast amount of total energy whileproviding similar or better perfor-mance than existing technologies.At the same time, we’re ensuringthat renewable resources such assolar thermal coupled with naturalgas and renewable methane pro-duced from biomass help secureour domestic energy future.”

At the Forefront of CarbonManagement InitiativesSince natural gas is the cleanest-burning fossil fuel, producing lowerlevels of greenhouse gas emissionsthan coal and oil, there is hugepotential for it to play a significantrole in a carbonmanagement pro-gram. According to Neil Leslie, GTI’sManager, Residential/CommercialBuildings R&D, “We need to con-tinue educating consumers, busi-nesses, government officials andregulators that natural gas can bea large part of the solution to ourclimate change concerns, as

Heat Up.Cool Down.Energy andhousing prices,economicactivity, climatechange—andmore—heatingup and coolingdown. It’s beenquite a rollercoaster ride of late.

Recently, natural gas priceshave dropped dramatically, withnew supplies such as gas shaleshelping to lower prices, createnew domestic jobs, providegreater energy security, andimprove trade balance.This isa welcome bright spot duringan extremely difficult period.

It’s no secret that the economyis in a tailspin, with a downturnnot seen in over 25 years.History shows that economiccycles occur and hopefully arebound will emerge later thisyear, bringing stability to theheavy-hit housing sector andrelated industries includingconstruction, appliance manu-facturing, and the like.

With the economy in a state ofcooling, climate change is bothheating up and cooling down.

Average global temperatureshave cooled from a high-watermark in 1998, sparking ques-tions about climate models andfuture predictions. A recent PewResearch Center study reflects asoftening of public urgency,ranking global warming 20thout of 20 “top priority” topics.Regardless, U.S. climate changelegislation or regulation islooming on the horizon,possibly in the form of a

the Energy to Lead

Recently, the U.S. and globalenergy markets have been

characterized by substantial volatil-ity. Pricing peaks and valleys havebecome common; huge shiftsdramatically occur, sometimes ona daily basis, while energy userstry making sense of it all.Through it all, a common theme

resonatingwith government agencies,regulators, utilities, and end-users, isthat a coordinated focus on energyefficiency and environmental stew-ardship is needed to guide us tothe future.GTI’s Residential/Commercial

Buildings Research and Develop-ment (R&D) program is addressingthese issues and concerns throughstrategic technology and efficiencyinitiatives that aim to reduce energyconsumption and carbon emissions.

Reducing EnvironmentalImpacts through IncreasedEquipment EfficienciesFrom an environmental perspective,statistics show that residentialhomes and commercial buildingsare currently consuming over 40quadrillion BTUs (or Quads) ofenergy each year, contributingnearly 40% of total U.S. carbonemissions to the atmosphere—much of this from electricity gener-ation, transmission, and use.“This trend has been steadily

occurring for over twenty years andit’s not something we foresee chang-ing,” says Bill Liss, GTI’s ManagingDirector, End Use Solutions Sector.“GTI, working with our sponsorsand other partners, has been leading

opposed to mistakenlybeing considered partof the problem.”To drive his point

home, Leslie pointsto GTI analysis(follow-up work toa highly regarded2008 American GasFoundation report) that indicatesthe potential for the natural gasindustry to reduce over 370millionmetric tons of carbon emissionsannually and savemore than3.5 Quads of energy.“The direct use of natural gas

in high-efficiency equipment cansignificantly reduce carbon emis-sions by displacing older, lessefficient electric appliances, such aswater heaters, that are used in boththe residential and commercialsectors,” he adds.“Whenwe lookat the full fuel-cycle efficiency ofnatural gas used in residential andcommercial equipment and appli-ances, it contributes far less carbonemissions to the atmosphere thancoal-producedelectricity thatdomi-nates inmanyregionsof thecountry.”

outside partners. The hybrid opti-mized tankless (HOT) water heateris an emerging technology equippedwith innovative control strategiesthat incorporate the best aspects ofboth storage tank and tanklesswater heaters.GTI, in a project originally

funded by the California EnergyCommission (CEC) as well as theGTI SustainingMembership Program(SMP), is conducting modelinganalysis and laboratory breadboardtesting of this water heating systemconfiguration. Follow-on supportfromUtilization Technology Devel-opment, NFP (UTD) will take thetechnology to the next level andprototype, lab evaluate, and fieldtest a potential product offering.

Another project funded by UTDthat continues to generate interest,due to its potential to provideenergy savings of up to 40%, as wellas the ability to deliver comfort in anenvironmentally-friendlymanner, isthe hybrid solar thermal/naturalgas water heater. The objective ofthe project is to reducematerials,manufacturing, and installationcosts, three barriers to marketpenetration in the past.GTI is teaming with Solar Usage

“cap and trade” program.The implication of this for theenergy industry and consumersis enormous.

The buildings sector—homesand commercial buildings—are a major source of carbonemissions. But within thissector lies “low-hanging fruit”for cost-effective carbon reduc-tions through new appliancesand improved energy-efficientconstruction practices. In thisedition, GTI highlights oursuccessful R&D program direc-tion within the buildings area.

GTI also sits on the Boardof Directors of the Council forResponsible Energy (CRE)—alongwith the American Gas Association,Southern Gas Association, EnergySolutions Center, and numer-ous utilities—to promote thebenefits of natural gas tothe broader public.

Painting a Brighter Futurewith a Full Palette of R&D

GTI’s Residential and CommercialBuildings R&D program has a broadspectrum of end use solutions thatdeliver value to various stakeholders.Within this coordinated initiative,GTI continues to produce ground-breaking research within its labora-tories, often validating its findingsthrough field tests in partnershipwith original equipment manufac-turers (OEMs), as new energy effi-cient technologies are introduced,including EnergyStar-rated gas equip-ment and appliancesfor high performancegreen buildings.Recent rate decoupling initiatives

have helped foster energy efficiencyprograms (through rebates on newenergy efficient equipment) thatcan enhance opportunities forinnovative gas technologies to gaina foothold in reshaping America’ssustainable energy future. GTI ispoised to help deliver these oppor-tunities to themarketplace.

High-EfficiencyTechnologyGoes “Up on the Roof”On the commercial front,GTI, responding to interestfrom the Consortium forEnergy Efficiency (CEE) andits Gas Committee, along withseveral UTDmembers’ managedEnergy Efficiency Programs, isinvestigating themarket feasibilityof a high-efficiency gas packagedair conditioner (gas PAC) forrooftop applications.In a newly funded project by

UTD, GTI will be investigating theissues associated with the use ofcondensing furnace technology in arooftop gas heating/electric coolingpackage to determine solutions, andif cost-effective, proceed with amanufacturing partner(s) on a pathtoward commercialization.“Today’s gas PACs from themajor

HVACmanufacturers top out at justover 80% annual fuel use efficiency,but the potential exists to raiseefficiency levels well into the 90+%range with condensing technology,”notes Doug Kosar, GTI’s InstituteEngineer for End Use Solutions.Kosar adds that there are issues

that need to be addressed to makethe technology feasible, such asacceptable first-cost premiums;overall net energy savings potential(condensing furnace gas savingsversus fan electricity increaseswith the added condensing heatexchanger pressure drop); condens-ing heat exchanger corrosion; freezeprotection; and proper condensatedisposal on rooftops. GTI willaddress these issues first and then,if practical, will prototype a con-densing rooftop package withamanufacturing partner(s) tovalidate its performance in labora-tory evaluations and field tests.“If several technical and eco-

nomic issues can be successfullyaddressed, a packaged 5-ton airconditioner and 100,000 Btu perhour furnace rooftop unit that hasan increased annual fuel use effi-ciency from 80 to 93% could yieldsignificant energy savings andcarbon emissions reductions forcommercial users,” notes Kosar.

Energy efficiency andcarbon reduction oppor-tunities are not exclusiveto the residential/commercial buildingssector. GTI also continues

its robust program develop-ing highly efficient commercial

foodservice equipment such asrecent commercial successes, theAvantec conveyor and crossflowovens and the Stellar Sirius gas-fired steamer.

Addressing Venting Challengesin Multifamily SectorTechnology and equipment devel-opment is just one area whereGTI’s Buildings program is havinga positive impact on the environ-ment. For several decades, GTI hasbeen widely recognized as a leaderwithin the residential/commercialbuildings codes and standardsarena, often through its acclaimedventing R&D program.

Currently, GTI is involved inseveral UTD-funded venting pro-jects for both residential singleandmultifamily dwellings. Themultifamily sector, in particular,has presented challenges that havemade it tough for the gas industryto experiencemarket growth.“This market places a high value

on square footage, appearance, andamenities,” says Larry Brand, GTI’sR&DManager, Energy Efficiency.“GTI and its partners believe thateliminating installation barriersassociated with venting can play apart in supporting the continueduse of gas water heaters and fur-naces in this market.”

Brand adds that vent designs thataccommodate modern applianceoptions such as tankless waterheaters and condensing furnaces, aswell as Category I common ventedappliances, are needed to reduceand reverse themarket share ero-sion experienced over the pastdecade. “GTI is investigating thefeasibility of extending commonventing practices to high-efficiencyfurnaces and water heaters in multi-family buildings, to make better useof space constraints, and reduce anynegative impacts to neighboringbuildings such as visible plumesand ice formation on sidewalks anddriveways,” he says.

Carbon Information Manage-ment Center CommunicatesRelevancy of Natural Gas toImportant StakeholdersOver the years, one of GTI’sstrengths has been its ability tothink of alternative approaches totechnically-challenging opportuni-ties. In 2008, responding to the needfor policymakers, public utilitycommissions, trade allies, andconsumers to have better access toinformation on the issue of carbonmanagement, GTI launched theonline CarbonManagementInformationCenter (CMIC).The CMIC helps address natural gasindustry issues and opportunitiesin the evolving arena of carbonemission controls.Neil Leslie, whomanages the

CMIC, states, “In its first year ofexistence, the CMIC is proving to bea valuable resource for informationabout carbon emissions and foot-prints. Carbon emissions calcula-tion tools, case studies, technicaldata, and presentations forimproved regulations, codes andstandards are being developed orchanneled through the CMIC tohelp members inform policy mak-ers, public utility commissions,trade allies, and customers aboutthe significant environmental,energy efficiency, and cost savingsof efficient natural gas systems.

GTI’s Sustainable CommunityPlanning Efforts Help Commu-nity Development Position itselffor Prestigious CertificationGTI is also contributing to majorcommunity planning initiatives,providing energy modeling analysisand knowledge-base tools andguidelines that help cities effectivelymanage growth in ways that opti-mize energy use andminimizeadverse environmental impacts.These efforts can ultimately helpshape the carbon footprint of entiresubdivisions and small communities.GTI has been working with the

Community Development Depart-ment of the City of ChulaVista,California, the CEC, and otherpartners to assist in the develop-ment of several energy-efficient

communities within the City’sredevelopment area.In May 2009, GTI and the

sustainable community team, incollaboration with developer,Wake-land Housing and DevelopmentCorporation, will realize the fruitionof their efforts as LosVecinos, ChulaVista’s greenest affordable housingcommunity, celebrates its grandopening. LosVecinos is the culmina-tion of redevelopment of 1.35 acresof land, with a building complexconsisting of 42 residential units.LosVecinos is targeted for LEEDPlatinum Certification, the highestdistinction in green building.“After extensive modeling and a

cost-to-benefit analysis of energy-efficient buildingmaterial andequipment options using GTI’sBuilding Energy Analyzer, a set ofeconomically-feasible energy effi-ciency upgrades were identified,”says Marek Czachorski, GTI’s

Institute Engineer, Residential/Commercial Building Efficiency,and the Institutes’ programmanager for the project. “Thestudy proved that if the complexwas constructed incorporatingall of GTI’s energy-efficientbuildingmaterial and equipment

options recommendations, as wellas an optimized photovoltaic (PV)system, its annual electric energyconsumption (kWh/year) would be

51% lower and its peak electricdemand (kW) 12% lower than if thecomplex were built to merely meetthe California Title-24, 2005 buildingenergy efficiency standard.”Another ChulaVista

project examined amixed-use residential andcommercial developmentto be built on a 5.5-acreparcel of land. A GTI studyshowed that using energy-efficientbuildingmaterials and applianceswith the addition of rooftop photo-voltaic (PV) arrays can reduce annualelectric consumption (kWh/year) byover 45% and peak annual electricdemand (kW) by almost 35% ascompared with the Title-24approach. These reductions trans-late to over a 30% reduction of CO2.A number of public domain

documents are being prepared bythe GTI sustainable communityteam (which includes San DiegoState University), including oneentitled, Creating Energy-EfficientCommunities in California: A Tech-nical Reference Guide to Buildingand Site Design.

Partnering for ProgressGTI is continuing its focus on energyefficiency and green buildingsthrough relationships with notableorganizations such as the CEE, andthe American Council for an EnergyEfficient Economy (ACEEE), as wellas continuing its decades-longactive partnerships with suchgroups as AGA and the EnergySolutions Center. These allianceswith front-line organizations helpGTI stay at the forefront of energyefficiency issues, while providingvaluable input to the Institute as itshapes its future R&D programs.“GTI’s strategic, multi-tier

approach to residential and com-mercial buildings R&D is allowingus to effectively navigate the criticalthemes and issues important to thesuccess of many carbonmanage-ment and energy efficiency pro-grams,” adds Liss. “In collaborationwith our industry partners andsponsors, we have the potential tohelp address future energy needs forgenerations to come.” � �

services in the growing Southeasternmarkets.”Lisk says that a major Piedmont

initiative is to continue promotingthe clean and efficient use of naturalgas. The utility believes that direct-use of natural gas in customers’homes and businesses for applica-tions such as home heating andwater heating is the most efficientuse of U.S. natural gas resourcesand also results in fewer greenhousegas emissions.“Because of today’s heavy focus

on the environment and the imple-mentation of energy efficiencyprograms, the alignment of interestsbetween energy companies andtheir customers—through innova-tive rate structures and designs—presents real opportunities forachieving our company’s collectiveenergy and environmental goals

of sustainability,” he adds“We feel strongly that thisalignment requires aclear and consistentcommunicationstrategy with our cus-tomers, potentialcustomers, and regula-tors and legislators.”Lisk continues, Piedmont

Natural Gas joined UTDbecause they strongly believe thatend use R&D is a strategic compo-nent for the future success of thenatural gas industry. “Participating

in UTD provides an opportunityfor Piedmont to have a voice at thetable during the shaping of ourindustry’s end use R&D strategy,something that can positivelyimpact our company’s future.”Lisk notes that one of the most

rewarding experiences in participat-ing in UTD has been the relation-ships built not only with GTI andUTD staff, but with peer membersof other utilities facing the sametypes of business and industrychallenges as Piedmont.UTD is not the only collaborative

R&D initiative Piedmont NaturalGas has recently been involved in;the utility is a foundingmember ofthe Council for Responsible Energy.That organization is a nationalcoalition of gas utilities who formedto promote consistent messagingand advertising of the energy effi-ciency and environmental benefitsassociated with natural gas in enduse applications.Lisk concludes,“The natural gas

TheU.S. continues its effortsto cost-effectively develop

alternative fueling and infrastruc-ture technologies that canminimizeits long-standing dependenceon foreign petroleum, as well ascontribute to a cleaner, greenerenvironment. GTI, through thesupport of its sponsors and severalcommercialization partners, isplaying a significant leadershiprole on several fronts to makethese efforts a reality.For more than 40 years, GTI

has performed successful research,development and demonstration(RD&D) of advanced hydrogentechnologies, products, andprocesses; its fuel cell work alonehas resulted in over 80 U.S. patents.The Institute also draws on itsdecades-long leadership role in thedevelopment of natural gas vehicleproducts and technologies and theassociated complexities of a com-pressed gas fueling infrastructure.

“GTI’s history in the areas ofproduction (through reforming,gasification, and electrolysis), aswell as hydrogen handling andsafety, helps us to successfullypartner with well-regarded originalequipment manufacturers (OEMs),like GreenField Compression, topackage technologies for end-usefueling applications,” says TonyLindsay, GTI’s Advanced EnergySystemsR&DManager. “It’s rewardingto see the highly technical advanceswe’ve achieved in the laboratory,such as with our small-scale steammethane reformation (SMR) process,now being transferred to the field.

State and Federal government,including DOE, and private industryfunded the development of theseadvanced fueling and vehicle tech-nologies. The Texas Commission onEnvironmental Quality (TCEQ), theTexas State Energy ConservationOffice (SECO), the U.S. Departmentof Transportation (DOT), GTI,GreenField Compression, and theUniversity of Texas at Austin addedfurther funding to commercializethe hydrogen fueling technologyand deploy the fuel cell hybrid bus.

Fueling Station aMajor Part ofNational Hydrogen ConferenceGTI’s installation of a hydrogenfueling station in Columbia, SouthCarolina was targeted specificallyto coincide with the 2009 NationalHydrogen Association conferenceand Columbia Fuel Cell Challenge,held in late March 2009.GTI and the Center for Trans-

portation and the Environment(CTE) of Atlanta, Georgia, submittedthe winning proposal for fundingfrom the South Carolina ResearchAssociation (SCRA) to design andinstall the system. As part of a two-year project, the station will be usedfor fueling a hydrogen fuel celldemonstration bus that is operated

by the University of South Carolina,as well as the local mass transitauthority.

Missouri University of Science andTechnology (Rolla) GoesMobileIn August 2008, GTI’s mobile hydro-gen unit along with a GreenFielddispenser, were installed and arecurrently being demonstrated fora two-year period at theMissouriUniversity of Science andTechnology(MST). The trailer-mounted stationconsists of an on-board fuel proces-sor, clean-up, compression, andstorage. It produces 10–15 kg/dayand serves the University’s remotehydrogen dispenser.GTI provided design, engineering,

and installation of the unit for thesite. The University ispart of a demonstra-tion programwithFordMotor Com-pany to operatetwo Ford shuttle-vans between theUniversity campusand nearby Fort LeonardWood.The station began operationwithdelivered hydrogen at the Universityin August 2008 and will beginproducing its own hydrogen on-sitefrom natural gas using GTI’s SMRtechnology in the spring of 2009.

GTI Focusing on a Hydrogen-Fueling FutureAlthough GTI has a number ofsuccessful fueling technologies inthe field for demonstration, Lindsay

notes that there is more work tobe done to reduce costs, improvereliability, and increase awarenessabout hydrogen as a transportationfuel before hydrogen fuelingbecomesmainstream.GTI continues to pursue R&D

projects to address these issues.One project hoping to expand thenecessary infrastructure for fuelinghydrogen vehicles is the develop-ment of a residential hydrogenfueling appliance (RHFA). GTI iscurrently involved in the prelimi-nary design phase of a RHFAintended to be able to either slow-fill a vehicle at home unattendedovernight, or fast-fill a hydrogenfuel cell vehicle within an hour,from near empty condition.“The eventual adaptation of

hydrogen-fueled vehicles and thecorresponding fueling infrastructureis a complex challenge for researchersand original equipment manufac-turers,” says Lindsay. “This is aboutmore than creating a safe and supe-rior domestic technology. Develop-ing an economical and standardizeddistribution system for the fuel isalso critical to its success.We feelconfident that GTI, along with itssponsors and partners, have devel-oped the proper strategic directionto successfully bring this form ofvehicular energy to themarket andwill continue to adapt it over timetomeet market criteria.”For more information about
