NYC energy benchmarking (Local Law 84)
Energy use and emissions
109 West 27th Street's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score, and Local Law 33 letter grades come from that score, so the filing does not yield an A to D grade.

Its greenhouse gas emissions were about 224 metric tons of CO2e (4.96 kg per square foot).

Local Law 97 emissions limit
At its 2024 energy use, 109 West 27th Street comes to about 165 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 411 tons for 2024 to 2029 (40% of the limit), so it would owe no penalty. From 2030 the limit drops to 142 tons and the same energy use counts as about 83 tons, still under the limit.

It is not the building's Local Law 97 report: that report can count renewable energy credits, solar and storage deductions and, for 2024 and 2025, the law's occupancy group limits where higher, and penalties can be reduced for good faith efforts.
