Frequently asked questions

Which large Boston buildings have the worst energy grades?

1153 Centre St reports the lowest ENERGY STAR score (1) among Boston buildings over 50,000 sq ft. BERDO 2.0 sets emissions standards for buildings over 20,000 sq ft from 2025, with an alternative-compliance payment of $234 per metric ton of CO₂e over the cap.

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.
