St Agnes HDFC's ENERGY STAR score of 27 compares with an average of 63 across the 22,829 that report a score; it scores higher than 16% of them and lower than 84%. Its site EUI of 99.1 kBtu/ft² is about 32% 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 7.9 kgCO₂e/ft² is about 51% above the group average of 5.2 kgCO₂e/ft².

At 104,187 sq ft, it is roughly in line with the average floor area of 100,951 sq ft for those buildings. It was built in 1910, 42 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 27 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 27 means the building performs better than about 27% of its national peers. BuildingCensus bands the score into report-card grades; 27 falls in band D — lowest band (1–54). It sits 48 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. St Agnes HDFC's 99.1 kBtu/ft² across 104,187 sq ft works out to about 10.3 billion Btu (3,026 MWh-equivalent) in 2024. Its source EUI of 120.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 343,404 kWh of electricity, 1,698 therms of natural gas and 7,889 thousand gallons of water for the year.

Which law requires St Agnes HDFC to report its energy use?
