This Guide is designed to help state and local policymakers to take full advantage of new policy developments by providing them with a comprehensive set of tools to support launching or accelerating residential energy efficiency programs. The Guide focuses on four categories of policies that have proven particularly effective in providing a framework within which residential energy efficiency programs can thrive: incentives and financing, making the value of energy efficiency visible in the real estate market, data access and standardization, and supporting utility system procurement of energy efficiency.

The report makes the case for establishment of common data collection practices for energy efficiency lending. The report reviews existing practices for the collection of four categories of data from energy efficiency financing programs: (1) customer data; (2) financial product and performance data; (3) facility-level data; and (4) energy efficiency project data. The report then identifies high-priority needs, characterizes potential uses for finance program data, and identifies use cases that describe how stakeholders use data for key objectives and actions.

This study focused on homeowner decision-making in response to home energy assessments, combined with the quality of the recommendations, the home energy assessment, and home energy labels. This report analyzes what assessments provide and what homeowners seem to want. It presents the results of a study of an existing home energy audit program pilot offered by Seattle City Light. From mid-2010 to late 2011, approximately 1,350 home energy assessments were completed in Seattle as part of Seattle City Light's program.

This report describes different approaches to energy efficiency finance taken by utilities.
