  1. Programs for Advancing High Efficiency Air Conditioningin Commercial and Industrial Buildings Howard Geller Workshop on Energy Efficiency Opportunities While Phasing Down HFCs Vienna, Austria July 9-10, 2018

  2. Southwest Energy Efficiency Project • Non-profit public interest organization, founded 2001 • Advances policies and programs to stimulate greater energy efficiency in six western U.S. states • Includes states and cities with very hot, dry climates; e.g., metro Phoenix and Las Vegas www.swenergy.org

  3. Overview of Electric Utility Energy Efficiency Programs in the Region • Utilities spending 2-5% of revenues on energy efficiency (DSM) programs • Customers are saving of 1-2% of electricity sales, per year • State policies driving these efforts: • Minimum energy savings standards or goals • Convenient cost recovery mechanisms • Decoupling of utility sales and revenues • Performance-based shareholder financial incentives

  4. A Decade of Electric Utility EE Programs in the Southwest Region Over 20 billion kWh/yr of electric savings as of 2017 Nine baseload power plants avoided (300 MW each) ~$7.5 billion in net economic benefits for households and businesses 80 million tons of avoided CO2 emissions during 2008-17

  5. Actions by Utilities to Advance More Efficient AC Systems in C&I Sector • Incentives for high efficiency AC equipment • Provided to customers and/or distributors • Incentives for evaporative cooling systems • Rebates on energy management and control systems; variable speed drives; WiFi-enabled smart thermostats • Training for HVAC companies and their technicians • Incentives for proper system sizing and installation

  6. Examples High Efficiency AC Programs for C&I Customers in the Southwest 2017 Programs Only • Salt River Project (Phoenix, AZ) • 790 projects • 37 GWh/yr of savings; 550 GWh lifetime savings • Utility cost - $0.005 per kWh of lifetime savings • NV Energy (Las Vegas, NV) • Incentives for high efficiency AC systems, VFDs, control systems, and smart thermostats • 28 GWh/yr of savings; 275 GWh lifetime savings

  7. Examples High Efficiency AC Programs for C&I Customers in the Southwest 2017 Programs Only • Xcel Energy – CO (Denver, CO) • 413 high efficiency AC projects • 11.3 GWh/yr of savings; 28 MWh/yr on avg. per project (milder climate) • 25,000 tons of high efficiency rooftop AC units sold through distributor incentives • Additional savings through incentives for energy management systems and fan/motor incentives

  8. Option for Hot, Dry Climates: Indirect Evaporative Cooling
