What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 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. 230 Park Avenue South's 87.9 kBtu/ft² across 311,789 sq ft works out to about 27.4 billion Btu (8,032 MWh-equivalent) in 2024. Its source EUI of 225.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,987,075 kWh of electricity, 5,480 therms of natural gas and 3,626 thousand gallons of water for the year.
