The Energy Department launched a new Buildings Performance Database, the largest free, publicly available database of residential and commercial building energy performance information. Currently, commercial and residential buildings account for approximately 70% of the electricity consumption in the nation. The database strengthens the Department's commitment to provide U.S. industry, state and local governments, and researchers with innovative energy data tools that can help cut energy waste and save money. This database will allow users to access energy performance data and perform statistical analyses on more than 60,000 commercial and residential buildings across the country.
