Frequently asked questions

Which large New York City buildings have the worst energy grades?

1980-2040 East Tremont Avenue - Parent Property reports the lowest ENERGY STAR score (1) among New York City buildings over 50,000 sq ft. Under Local Law 97, buildings over 25,000 sq ft face carbon caps with fines of $268 per metric ton of CO₂e over the limit, phasing in from 2024.

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.
