How does 723 REALTY L.L.C. 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. 723 REALTY L.L.C.'s ENERGY STAR score of 81 compares with an average of 63 across the 22,829 that report a score; it scores higher than 64% of them and lower than 34%. Its site EUI of 104.7 kBtu/ft² is about 40% above the average of 74.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 6.0 kgCO₂e/ft² is about 15% above the group average of 5.2 kgCO₂e/ft².
At 54,878 sq ft, it is about half of the average floor area of 100,951 sq ft for those buildings. It was built in 1929, 23 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 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. 723 REALTY L.L.C.'s 104.7 kBtu/ft² across 54,878 sq ft works out to about 5.7 billion Btu (1,684 MWh-equivalent) in 2022. Its source EUI of 135.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 231,096 kWh of electricity and 7,316 thousand gallons of water for the year.
