Focusing on Colorado Springs, Colorado, as a case study, the U.S. Department of Energy's Building America research team IBACOS suggests a win-win between a builder's investment in energy efficiency and that builder's ability to sell homes. Although this research did not ultimately determine why a correlation may exist, a builder's investment in voluntary energy-efficiency programs correlated with that builder's ability to survive the Great Recession of 2007 to 2009. This report explores the relationship between energy-efficiency ratings and the market performance of several builders in Colorado Springs.

This summary from a Better Buildings Residential Network peer exchange call focused on combining solar and home performance energy efficiency.

This summary report provides scientific results, lessons learned, and recommendations for driving energy efficiency in existing buildings on an urban scale. It includes program marketing lesson learned, such as: personal outreach and call to action events are critical marketing opportunities.

This report provides results, lessons learned and recommendations for driving energy efficiency in existing building on an urban scale based on the second year of the Energize Phoenix energy efficiency program.
