Frequently asked questions

Which large Honolulu buildings have the worst energy grades?

Anaha reports the lowest ENERGY STAR score (12) among Honolulu buildings over 50,000 sq ft. Honolulu's Ordinance 22-17 requires commercial buildings over 25,000 sq ft on Oʻahu to benchmark annually, with public disclosure of results.

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.
