Its site EUI of 121.0 kBtu/ft² is about 31% above the average of 92.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 8.0 kgCO₂e/ft² is roughly in line with the group average of 7.9 kgCO₂e/ft².

At 39,395 sq ft, it is about 82% below the average floor area of 224,815 sq ft for those buildings. It was built in 1920, 37 years earlier than the group's average year built (1958). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

What does an ENERGY STAR score of 17 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 17 means the building performs better than about 17% of its national peers. BuildingCensus bands the score into report-card grades; 17 falls in band D — lowest band (1–54). It sits 58 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. 156 Second Avenue's 121.0 kBtu/ft² across 39,395 sq ft works out to about 4.8 billion Btu (1,397 MWh-equivalent) in 2024. Its source EUI of 170.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 288,402 kWh of electricity and 37,813 therms of natural gas for the year.

Which law requires 156 Second Avenue to report its energy use?
