Buildings account for roughly 40% of the energy consumed in the United States. Recognizing the tremendous opportunity for energy and cost savings and associated health and environmental benefits, state and local leaders are advancing building energy benchmarking and transparency programs to support improved efficiency. Benchmarking and transparency provide the foundation for improved building energy performance. Building energy benchmarking means measuring a building’s energy use and then comparing it to the energy use of similar buildings, its own historical energy usage, or a reference performance level (e.g., based on a building energy code). This U.S. Department of Energy and Institute for Market Transformation resource guide provides state and local leaders with streamlined access to key existing resources for developing and implementing high-impact building energy benchmarking and transparency programs in their jurisdictions.
