Its site EUI of 28.0 kBtu/ft² is about 63% below the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.8 kgCO₂e/ft² is about half of the group average of 5.2 kgCO₂e/ft².
At 152,342 sq ft, it is about 51% above the average floor area of 100,951 sq ft for those buildings. It was built in 1927, 25 years earlier than the group's average year built (1952).

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). 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. 208 West 23rd Street - data's 28.0 kBtu/ft² across 152,342 sq ft works out to about 4.3 billion Btu (1,250 MWh-equivalent) in 2023. Its source EUI of 70.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,037,197 kWh of electricity and 7,299 therms of natural gas for the year.
