Frequently asked questions

Which large San Diego buildings have the worst energy grades?

Qualcomm Pac Center reports the lowest ENERGY STAR score (1) among San Diego buildings over 50,000 sq ft. San Diego's ordinance requires annual benchmarking for commercial buildings over 50,000 sq ft, with civil 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.
