Solar Heating & Cooling
    Technology Roadmap
--- funded by DOE Building Technologies Program

 •    Key European SHC Markets Down Up to 40% Last Year – Policy/Incentive
      Uncertainty and General Economy
 •    U.S. Household Net Worth Dropped Over $10 Trillion Between 2007 and Today
      – Much of it in Home Equity
 •    Businesses Holding Substantial Profits – But Not Spending/Hiring
       – Increase in Funds Available for Corporate Investment Nearly Doubled to
         $66.3 Billion from 1st Q to 2nd Q of 2010 (US BEA)
 •    Federal Government Deficit: $13.5 Trillion Total, $1.4 Trillion Annually
 •    Unemployment at 9.6% -- Peak was 10.6% in 1982
 •    Competition from New Technologies: Heat Pump Water Heaters and
      Instantaneous Gas Water Heaters
 •    Most Impact is in Existing Buildings - Until Recently Not a Focus for DOE
     October 15, 2010             [Solar Heating & Cooling]                  17
Technology Options/Goals
• Low-cost solar water heaters for zero energy homes in cold climates:
   – cost-competitive with natural gas water heaters,
   – 30% less source energy than gas tankless heaters (EF=0.8) and
   – $2,000 incremental system cost (2015)
• Low-cost systems for combined building heating, cooling, and water
  heating in zero energy homes:
   – 30% reduction in annual energy use than SEER 18 / AFUE 92.5%
      system and
   – 60% incremental cost (2020)
• Combined solar electric/solar thermal (PV/T) systems that will increase
  energy production 100% over a stand-alone PV system at just 20%
  incremental cost (2015)
• Solar Cooling: Field tests of solar cooling and dehumidification
  applications in commercial buildings
    October 15, 2010         [Solar Heating and Cooling]               18
Potential/Existing Efforts to Boost Deployment
•   Stronger integration/leveraging across programs for market transformation:

     – Leveraging Energy Star SWH, Rebuild America, Energy Smart Schools where
       SHC could easily fit

     – SETP Market Transformation program that already has connections to SHC

     – Strong testing/certification effort with SRCC and IEA-SHC are foundation for
       stronger standards and codes and Energy Star – Energy Star SWH success

     – FEMP and its clients including DoD and GSA with demand for renewable energy
       and potential SHC applications, leading by example

     – Workforce Development Initiative with NABCEP activities

•   Workforce development needs focus on near-term SHC markets. Training workers for
    jobs that do not exist will create a backlash.
