Building Energy Exchange STL

The Building Energy Exchange STL (BE-Ex STL) is a regional resource to help building owners, operators, and community members drive greater efficiency in the built environment. More specifically, BE-Ex STL will provide support to the local real estate community and building industry professionals as they work to improve their building’s performance and reduce their greenhouse gas emissions in accordance with the Building Energy Performance Standard passed unanimously and signed into law by the City of St. Louis in April 2020.

A formal launch of BE-Ex STL is scheduled for early 2022. It will work in partnership with the City of St. Louis, the Institute for Market Transformation (IMT), the Natural Resources Defense Council (NRDC), Washington University, along with other non-profits, businesses and institutions, including foundational support from Ameren Missouri, The Leon Lowenstein Foundation, Spire and Washington University.
