What do Los Angeles's least efficient buildings have in common?

70 of them score 10 or lower. By property type the list is led by multifamily housing (42), distribution center (12) and office (8). Their average site EUI is 124.8 kBtu/ft², about 174% above the citywide average of 45.6 kBtu/ft². Combined they cover 14.8 million square feet; the median ranked building has 94,642 sq ft.

The ranking covers buildings of 50,000 sq ft or more that report an ENERGY STAR score, ordered by score and then by floor area. EBEWE requires annual benchmarking plus audits/retro-commissioning every five years for privately owned buildings of 20,000 sq ft or more; non-compliance carries a $202 fee (LAMC §91.9712) plus possible late fees.

Frequently asked questions

Which large Los Angeles buildings have the worst energy grades?

3600 BARHAM BLVD reports the lowest ENERGY STAR score (1) among Los Angeles buildings over 50,000 sq ft. EBEWE requires annual benchmarking plus audits/retro-commissioning every five years for privately owned buildings of 20,000 sq ft or more; non-compliance carries a $202 fee (LAMC §91.9712) plus possible late fees.

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.
