Lenox Hill Neighborhood House's ENERGY STAR score of 77 compares with an average of 72 across the 2,519 that report a score; it scores higher than 46% of them and lower than 52%. Its site EUI of 40.8 kBtu/ft² is about 37% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.3 kgCO₂e/ft² is about 43% below the group average of 5.8 kgCO₂e/ft².
At 53,243 sq ft, it is about 74% below the average floor area of 205,440 sq ft for those buildings. It was built in 1928, 12 years earlier than the group's average year built (1940). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 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. Lenox Hill Neighborhood House's 40.8 kBtu/ft² across 53,243 sq ft works out to about 2.2 billion Btu (637 MWh-equivalent) in 2022. Its source EUI of 106.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 566,641 kWh of electricity and 3,873 thousand gallons of water for the year.
