How does 45 Gramercy Park North compare with other multifamily housing buildings in New York City?
The latest disclosures cover 33,022 multifamily housing buildings in New York City, out of 48,310 buildings citywide. 45 Gramercy Park North's ENERGY STAR score of 77 compares with an average of 63 across the 22,829 that report a score; it scores higher than 60% of them and lower than 39%. Its site EUI of 67.8 kBtu/ft² is roughly in line with the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.2 kgCO₂e/ft² is roughly in line with the group average of 5.2 kgCO₂e/ft².
At 83,300 sq ft, it is about 17% below the average floor area of 100,951 sq ft for those buildings. It was built in 1927, 25 years earlier than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
What does an ENERGY STAR score of 77 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In New York City, 43% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 45 Gramercy Park North's 67.8 kBtu/ft² across 83,300 sq ft works out to about 5.6 billion Btu (1,655 MWh-equivalent) in 2022. Its source EUI of 94.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 352,799 kWh of electricity for the year.
