Frequently asked questions

Which large San Francisco buildings have the worst energy grades?

201 Toland St reports the lowest ENERGY STAR score (1) among San Francisco buildings over 50,000 sq ft. San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.

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.
