Its site EUI of 113.0 kBtu/ft² is about 75% above the average of 64.5 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 37% above the group average of 5.8 kgCO₂e/ft².

At 37,727 sq ft, it is about 82% below the average floor area of 205,440 sq ft for those buildings. It was built in 1981, 41 years later 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 41 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 41 means the building performs better than about 41% of its national peers. BuildingCensus bands the score into report-card grades; 41 falls in band D — lowest band (1–54). It sits 34 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. LL97-221-17 NORTHERN BLVD's 113.0 kBtu/ft² across 37,727 sq ft works out to about 4.3 billion Btu (1,249 MWh-equivalent) in 2024. Its source EUI of 172.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 342,404 kWh of electricity and 30,959 therms of natural gas for the year.

Which law requires LL97-221-17 NORTHERN BLVD to report its energy use?
