The CAEA requires the energy performance of large commercial buildings (over 50,000 SF) and all public buildings to be rated with ENERGY STAR software and disclosed on a public website. To rate energy performance, utility data is collected for 1 year and then reported to the District Department of the Environment via ENERGY STAR Portfolio Manager, a free tool from the U.S. Environmental Protection Agency.
Beginning in 2010, public buildings of at least 10,000 SF were rated with ENERGY STAR and disclosed online via a publicly-available database.
For commercial buildings, owners are given a 1 year grace period between the reporting of their energy performance and the publication of their scores on the public website. Energy data must be first reported to the District Department of the Environment by the following dates:
- July 1, 2011 for buildings of 200,000 SF or more
- April 1, 2012 for buildings 150,000 - 200,000 SF
- April 1, 2013 for buildings 100,000 - 150,000 SF
- April 1, 2014 for buildings 50,000 - 100,000 SF
The District Department of the Environment is currently engaged in final rulemaking for the commercial buildings portion of the law.
