This study provides an overview of practices for quantifying and reporting avoided energy-water costs from demand-side measures. It also summarizes the regulatory guidance for incorporating water savings into cost-effectiveness screening for energy efficiency programs.

This paper describes existing barriers to integrating energy efficiency data into real estate markets, and illustrates recent efforts to address them. National cross-industry collaborations have resulted in standard data collection and transfer tools that allow home performance data to be shared across industries. Real estate markets in some regions have begun including these data into multiple listing services (MLS), making them visible during real estate transactions.
