21-09 Borden Avenue reported an ENERGY STAR score of 94 for calendar year 2024 in its Local Law 84 benchmarking filing. Under Local Law 33, as amended by Local Law 95 of 2019, a score of 85 or higher earns an A, 70 to 84 a B, 55 to 69 a C and under 55 a D, so 94 earns an A. The Department of Buildings assigns the grade a building posts, so the posted label can differ if a filing was corrected. Its site energy use came to 35 kBtu per square foot, less than half the national median of 85.6 for a similar property. Its greenhouse gas emissions were about 635 metric tons of CO2e (2.89 kg per square foot).

At its 2024 energy use, 21-09 Borden Avenue comes to about 524 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,668 tons for 2024 to 2029 (31% of the limit), so it would owe no penalty. From 2030 the limit drops to 592 tons and the same energy use counts as about 370 tons, still under the limit. 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. It is not the building's Local Law 97 report, which can count credits and deductions this estimate cannot.
