The City of Fort Collins, Colorado increased the number of homes that are energy efficient through the use of community-based social marketing. Strategies to maximize impact included identifying neighborhoods based on data analysis, simplifying the process for completing upgrades, and using trusted messengers for delivery of tailored messages on energy efficiency services.

This case study highlights the low-income programs of Efficiency Vermont, the nation’s first public energy efficiency utility, which aims to reduce these customers' high energy burden, freeing up money that they can spend on food, housing, and other necessities. These low-income programs have saved enough electricity to power nearly 8,000 Vermont households for a year and offer solutions that eliminate or reduce up-front costs for residents, a typical barrier to improving energy efficiency in low-income households. Its multifamily energy efficiency program helps renters and building owners save energy, addressing the “split incentive” barrier in which owners have little reason to invest in efficiency measures that benefit tenants who pay their own energy bills.

This document profiles the Chicago-area non-profit Elevate Energy, which offers a full-service energy efficiency retrofit program for owners of and tenants in affordable multifamily buildings in eleven states.

This case study highlights how EmPOWER Maryland’s low-income programs have helped to reduce or eliminate the up-front costs of efficiency upgrades, minimize administrative burden on participants, and provide coordinated services through a statewide network of trusted partners.

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.

Home heating is the largest energy expense for most U.S. homeowners and accounts for nearly 30% of energy used in the nation's residential buildings. Millions of homeowners in colder regions of the country do not have natural gas available, leaving furnaces to be fueled with heating oil, propane, or electricity. This can often result in higher heating bills for homeowners. However, soon, these 2.6 million homeowners living in cold climates will have another, efficient home heating option. Oak Ridge National Laboratory (ORNL), collaborating with Emerson Climate Technologies, developed a prototype for an air-source heat pump for the colder regions of the country--one that heats better and uses significantly less energy.
