How does Sierra 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. Sierra's ENERGY STAR score of 21 compares with an average of 63 across the 22,829 that report a score; it scores higher than 12% of them and lower than 87%. Its site EUI of 89.0 kBtu/ft² is about 19% 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 5.8 kgCO₂e/ft² is about 12% above the group average of 5.2 kgCO₂e/ft².
At 343,534 sq ft, it is about 240% above the average floor area of 100,951 sq ft for those buildings. It was built in 2001, 49 years later 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 21 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 21 means the building performs better than about 21% of its national peers. BuildingCensus bands the score into report-card grades; 21 falls in band D — lowest band (1–54). It sits 54 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. Sierra's 89.0 kBtu/ft² across 343,534 sq ft works out to about 30.6 billion Btu (8,961 MWh-equivalent) in 2022. Its source EUI of 154.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,525,860 kWh of electricity and 13,931 thousand gallons of water for the year.
Which law requires Sierra to report its energy use?
