Frequently asked questions

Which large Chicago buildings have the worst energy grades?

Digital Lakeside reports the lowest ENERGY STAR score (1) among Chicago buildings over 50,000 sq ft. Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.

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.
