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.

Fort Collins Utilities and partners, Platte River Power Authority (PRPA) and CLEAResult, launched Efficiency Works-Home program, the Efficiency Works- Neighborhoods (EW-N) Pilot. The Pilot is a new model of Utility Energy Efficiency conservation program that is designed for the scale and comprehensiveness of EE and renewables needed to meet the City of Fort Collins Climate Action Plan in the existing home sector.

The NorthernSTAR and U.S. Department of Energy Building America Program partnership investigated a new model to deploy building science-guided performance solutions to homeowners. This research explored three aspects to market delivery:
1. Understand the homeowner's motivations regarding investing in building science-based performance upgrades.
2. Determine a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks.
3. Access a business model that will manage all aspects of the contractor-homeowner performance professional interface to ensure good upgrade decisions throughout time.
