Its site EUI of 40.3 kBtu/ft² is about 38% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. WSM - 99 Madison Avenue's 40.3 kBtu/ft² across 120,000 sq ft works out to about 4.8 billion Btu (1,417 MWh-equivalent) in 2023. Its source EUI of 90.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 975,493 kWh of electricity, 6,365 therms of natural gas and 2,225 thousand gallons of water for the year.
