Frequently asked questions

Which large Portland buildings have the worst energy grades?

Restaurant Depot reports the lowest ENERGY STAR score (1) among Portland buildings over 50,000 sq ft. Portland requires commercial buildings over 20,000 sq ft to report energy performance annually, with civil penalties for buildings that fail to comply.

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.
