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.

The Southeast Energy Efficiency Alliance (SEEA) has prepared this assessment of the Southeast’s multifamily sector to better understand the current stock of multifamily units; regional and state multifamily construction trends; utility multifamily energy efficiency programs; and state and local policies and programs focused on the multifamily sector.

This guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.
