What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. 443 Park Avenue South's 58.6 kBtu/ft² across 75,588 sq ft works out to about 4.4 billion Btu (1,298 MWh-equivalent) in 2022. Its source EUI of 104.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 564,662 kWh of electricity for the year.
