Frequently asked questions

Which large California buildings have the worst energy grades?

Moreno Valley Logistics Ctr #1 reports the lowest ENERGY STAR score (1) among California buildings over 50,000 sq ft. AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.

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.
