Its site EUI of 34.6 kBtu/ft² is about half of the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 52,628 sq ft, it is about 74% below the average floor area of 205,440 sq ft for those buildings. It was built in 2018, 78 years later than the group's average year built (1940).

What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 18 SPENCER STREET's 34.6 kBtu/ft² across 52,628 sq ft works out to about 1.8 billion Btu (534 MWh-equivalent) in 2024. Its source EUI of 96.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 533,932 kWh of electricity and 434 thousand gallons of water for the year.
