How does 3407 Dekalb Avenue 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. 3407 Dekalb Avenue's ENERGY STAR score of 82 compares with an average of 63 across the 22,829 that report a score; it scores higher than 66% of them and lower than 33%. Its site EUI of 69.7 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 4.5 kgCO₂e/ft² is about 14% below the group average of 5.2 kgCO₂e/ft².

At 52,500 sq ft, it is about half of the average floor area of 100,951 sq ft for those buildings. It was built in 1926, 26 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 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 3407 Dekalb Avenue's 69.7 kBtu/ft² across 52,500 sq ft works out to about 3.7 billion Btu (1,072 MWh-equivalent) in 2024. 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 186,543 kWh of electricity, 30,202 therms of natural gas and 5,051 thousand gallons of water for the year.
