In this presentation, state and nonprofit leaders in Colorado and Connecticut discuss their policy and program efforts to offer rooftop and community solar and weatherization services and how they are scaling their programs to meet the needs of the underserved income-eligible market.

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.
