Frequently asked questions

Which large St. Louis buildings have the worst energy grades?

See the table for the latest ranking. St. Louis was the first Midwest city with a Building Energy Performance Standard (Ordinance 71132) — covered buildings must meet EUI targets on 4-year cycles.

Does a low score mean the building breaks the law?

No. A low ENERGY STAR score is a national efficiency percentile, not a violation. It does correlate with exposure under building-performance standards (carbon caps, retrofit mandates), which is why owners, lenders and retrofit contractors watch these lists.
