The estimate is the taxable value times the class rate. It leaves out abatements, payment-in-lieu-of-taxes agreements and charges, so the actual bill can differ.

Local Law 97 emissions limit
At its 2024 energy use, 227 East 45th Street comes to about 690 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,149 tons for 2024 to 2029 (60% of the limit), so it would owe no penalty.

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.

What is the energy grade of 227 East 45th Street?

This is an estimate from the owner's 2024 benchmarking filing using the coefficients and per-use limits in the law and the Department of Buildings rule, at $268 per ton over.
