Believe It Or Not!

- Solar heating for staying cool in buildings!?

- NASA is doing a project with the Navy at an Air Force Base!?

- A Hawaiian company is installing a Chinese chiller in Arizona!?

Believe It! It's true!

- NASA organized a collaborative technology demonstration project with the DOD

ESTCP Program to get performance data on concentrated solar collectors

supplying the energy for absorption chillers to air condition building

- Project team developed proposal; went through ESTCP project selection and

funding process

- Demonstration site was selected from list ofpotential sites based on feasibility of

facility and eagerness of base energy managers

Risk to Mission

Rising energy unit costs eroding mission funding

Trend: Buying less yet spending more

• Since FY 1995, use down 15°..'0 and unit costs up 64%

Significance of air conditioning

DOD studies have concluded that air conditioning accounts for 30-60% of total

energy expenditures

Why use solar thermal energy? To offset energy provided from the grid

Energy and Water

SERDP and ESTeP's EnerfJY and Water program areasupports the demonstratk:Jn of InnovativetechnoloQles to redJce the Department of Defense's(DoD) installation enerQY consumption and carbonfootprint, Improve enerQY security, and facilitate .s,water conservation.

DoD manages more than 300,000 buildings on some SOD InstaGationS ttYOl.lQhout theU1ited States. As the nation's largest shJIe enerfJY consuner, DoD spends close to $4biIion e_y year on facWty enerQY consumption. Fixed InstaUatlons and the non-tacticalvehicles used on them contribute nearly 40 percent of the mWtary'S Ql'eenrouse Qasemissions.

DoD has made enerQY policy a hl;lh priority. Its QOai Is to Improve enerQY conservation andefficiency, reduce water and enerfJY demand, and Increase the use of renewable enerQY,Advances wa provide m~tary installations with Increased flexibKity, lower costs, andreduced l;lI'eenl-o.Jse Qas enisslons,

SERDP and ESTCP invest In nnovatlve tec:hnolcJQtes and methods to help achieve theseQOals. ThrClUlJh the EnerQY and Water prOQram area, DoD's instalatlons serve as a testbed for cuttlnQ-edoe techr1ologes developed by researchers from Industry, universities,and federal aQancies. By reducR1l;J real and perceived risks, these demonstrationsaccelerate the broader deployment of h10vatlve enerQY technoloQles across DoD.

Areas of Investment indJde:

Meeting DoD's Environmental Challenges

• technologies that support sustainable building design and operations, Incudinginnovative energy-effic"nt lighting, heating, and air conditioning systems

• renewable energy, such as \dar and wind power, and other distributed-energygeneration sources

• systems that enable better management of energy resources, such as irmoved energystorage and control techniques

• methods and technologies to reduce water demand

Concentrated Solar Air Conditioning for Buildings •Description:

Electricity from utility grids is not always reliable oraffordable, presenting problems for building air conditioningin hot climates.

New solar thermal energy system offer advantages ofproven technology, small footprint, easy installation, andaffordability.

Need is to increase energy efficiency, and percentagerenewable consumption. (Summer AC loads account for30-60% of total energy expenditures at 000 facilities.)

Project objective is demonstrate that solar collectors canbe integrated with absorption chillers to provide arenewable energy based source of air conditioning.

Stakeholders:Work Partners: Navy [Principal Investigator], Sopogy[Turnkey], TESS/Enovity [subcontractors]; Davis-MonthanAFB (demo site in AZ)Other: NASA (JSC & DFRC), HQ EMD

Project Approach:Collect baseline operational dataInstall MicroCSPTM and absorption chillerCollect at least 12 months of operational dataDetermine offset electrical grid energy quantities andsavingsProve cost-effective alternative to fossil fuel based energy

Alternatives:Parabolic solar collectors coupled with absorption chiller

Progress: Demonstration Plan approved in May; collectingbaseline data; Construction underway

Period of Performance: May 2010 to February 2013
