Frequently asked questions

What is the most energy-efficient large building in Chicago?

RiverView Condominium Association tops the list with an ENERGY STAR score of 100 among Chicago buildings over 50,000 sq ft in the latest Chicago Energy Benchmarking Ordinance disclosure.

Why only large buildings?

Restricting the ranking to buildings over 50,000 sq ft keeps it meaningful — perfect scores are common among small buildings, while running a high score at scale is the real efficiency achievement.
