What does an ENERGY STAR score of 66 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 66 means the building performs better than about 66% of its national peers. BuildingCensus bands the score into report-card grades; 66 falls in band C — below median (55–69). It sits 9 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. 136 East 64th St's 66.0 kBtu/ft² across 150,572 sq ft works out to about 9.9 billion Btu (2,912 MWh-equivalent) in 2024. Its source EUI of 98.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 781,226 kWh of electricity and 1,067 therms of natural gas for the year.
