DC’s Building Energy Performance Standards were set forth in Title III of the Clean Energy DC Omnibus Act of 2018. The Act states that, starting in 2021, owners of buildings over 50,000 square feet that are below a specific energy performance threshold will be required to improve their energy efficiency over the next 5 years. Projects below the performance threshold will be able to choose between a performance pathway, which requires that they document a 20% reduction in energy usage over the 5 year compliance period, or a prescriptive list of required energy efficiency measures.
