What is the Building Energy Performance Standard?
The St. Louis Board of Aldermen unanimously passed and Mayor Krewson signed into law, St. Louis’s Building Energy Performance Standard in May of 2020, making St. Louis the 4th jurisdiction in the country and the 1st in the Midwest to adopt this ambitious law to mandate significant reductions in building energy use.
The ordinance covers municipal, commercial, institutional and residential properties 50,000 square feet and larger. By May 2021, the City will set an energy performance standard for each property type based on local benchmarking data. The standards will be set to impact the highest energy users in each property type. Property owners will have the flexibility to decide what combination of physical or operational improvements can best achieve the standard and will have until May 2025 to reduce their energy use to comply. To ensure that building energy use continues to improve over time, the City will update the standards and increase energy performance requirements within a year of the conclusion of each four-year compliance cycle.
