1 Energy Efficient Residential Ceiling Fans: A Really Cool Idea! by: Noah Horowitz Natural Resources Defense Council (415)

2 What’s a Ceiling Fan?  Inefficient Motors  Poor Blade Design  Up to 5 Incandescent Lamps Giving Off Heat Annual Residential Ceiling Fan Sales: 19 MILLION!

3 Energy Consumption  Average Home Has 1.5 Fans (varies considerably by region)  Typical Energy Usage: 346 kWh/yr. per fan or 519 kWh/yr. per home  Energy Consumption About the Same as a New Efficient Refrigerator

4 Energy Savings Potential  Reduce Fan Energy Consumption by 60%  Additional Savings Potential from Controls and Thermostat Adjustment  National Potential Savings from New Fan Sales  3.9 billion kWh/yr.  3 million tons CO 2 /yr.

5 Roadmap for Transforming the Market  Perform Research on Usage  Create Testing and Reporting Infrastructure  Develop E-Star Specification  Provide Design Assistance to Ceiling Fan Industry  Develop Utility Programs for New Construction and Remodeling Markets

6 Research  Need Better Data on Hours of Operation of Fans and Lighting Systems  Have a Few Utilities in Different Climactic Regions Sponsor Research

7 Testing and Reporting  Test Method Exists for Measuring Air Flow and Power Consumption  Work with Air Movement and Control Association (AMCA) to Create Reporting Infrastructure

8 Energy Star Label  Have Energy Star Program Develop Specification  Obtain MOUs from Manufacturers  Integrate into Other E-Star Promotional Programs

9 Industry Assistance  Offer Design Assistance via Seminars  Lighting - Lighting Experts (eg. LBNL), Lighting Suppliers (lamps and ballasts), and Fan Manufacturers  Motors - Motor Manufacturers, Efficiency Experts (DOE, ACEEE, etc.), and Fan Manufacturers  Requires Modest Financial Sponsorship (CEE(?))

10 Utility Programs  Promote E-Star Fans  Integrate Into New Homes and Remodeling Programs  Create Retail Strategy  Consider Technology Procurement
