How does South Star Condominium 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. South Star Condominium's ENERGY STAR score of 67 compares with an average of 63 across the 22,829 that report a score; it scores higher than 48% of them and lower than 51%. Its site EUI of 59.1 kBtu/ft² is about 21% below 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 4.7 kgCO₂e/ft² is roughly in line with the group average of 5.2 kgCO₂e/ft².
At 200,610 sq ft, it is about twice 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 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. 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. South Star Condominium's 59.1 kBtu/ft² across 200,610 sq ft works out to about 11.9 billion Btu (3,475 MWh-equivalent) in 2024. Its source EUI of 100.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,112,540 kWh of electricity, 16,464 therms of natural gas and 6,418 thousand gallons of water for the year.
