How does 43-30 48th Street 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. 43-30 48th Street's ENERGY STAR score of 79 compares with an average of 63 across the 22,829 that report a score; it scores higher than 62% of them and lower than 37%. Its site EUI of 68.8 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 4.3 kgCO₂e/ft² is about 17% below the group average of 5.2 kgCO₂e/ft².
At 89,530 sq ft, it is about 11% 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 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 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. 43-30 48th Street's 68.8 kBtu/ft² across 89,530 sq ft works out to about 6.2 billion Btu (1,805 MWh-equivalent) in 2023. Its source EUI of 91.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 282,734 kWh of electricity, 51,969 therms of natural gas and 5,657 thousand gallons of water for the year.
