New energy standards in St. Louis mean changes for 65% of big buildings

Buildings across St. Louis of 50,000 square feet or more must comply with new energy guidelines — or face fines of up to $500 a day beginning in 2025. The manager of the city's new Office of Building Performance explains the new rules, while Cara Spencer, director of the new Building Energy Exchange St. Louis, explains how her organization will help building owners comply.
