About BE-Ex STL

St. Louis City’s landmark Building Energy Performance Standards – just the fourth of its kind in the US – put the city at the center of advancing policy to address energy efficiency.

Our Mission

Greenhouse gasses are driving major shifts in the climate of our earth. In the City of St. Louis, residential, commercial and industrial buildings account for 80% of greenhouse gas emissions – both day to day operations and during the design and construction. Reduction in consumption of energy in our buildings represents a tremendous opportunity to reduce emissions, save money, create jobs and protect public health. 

Our Mission is to advance building energy performance by mobilizing the professional expertise, funding, and technical resources the real estate industry needs to address affordability, improve the health and comfort of residents, and position St. Louis as a resilient and carbon-neutral region.

St. Louis is Leading the Way

St. Louis jumped to the forefront of sustainability by passing and signing into law critical regulations to reduce greenhouse gas emissions —Building Energy Performance Standards (BEPS). 

This landmark policy — just the fourth of its kind in the US and the first in the Midwest — put the City of St. Louis at the center of advancing policy to address energy efficiency and will help make St. Louis a climate ready and carbon neutral region.

BE-Ex STL was borne out of a desire to help building owners comply with regulations and to serve as a regional resource to reduce energy consumption and greenhouse gas emissions.

BE-Ex STL's Commitment to
our St. Louis Community

Racial Inequity & Our Building Stock Condition

The condition of our regional building stock reflects decades of racial inequality leading to substandard living conditions for many people of color and a lack of opportunity for acquiring generational wealth through real estate. BE-Ex STL initiatives must recognize that history and find opportunities to heal these historic injustices through community empowerment, housing stability, and improved health. We value multi-racial, multi-generational partnerships that are considerate of the lived experiences of residents while offering mutually-beneficial solutions for both building owner and tenant.

Operational Strategies to Grow Diversity

BE-Ex STL will engage in operational strategies that will continue to grow diversity within the BE-Ex STL board, future staff, and all participating stakeholders. We recognize that time commitment, cost of participation, and cultural accommodations must be considered to ensure diverse participation across all initiatives. Through our events and speaking opportunities, we strive to amplify the voices of historically underestimated communities that are often disproportionally affected by climate change and promote their work and achievements to the broader regional community.
