What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. HHH REALTY CORP.'s 69.9 kBtu/ft² across 118,582 sq ft works out to about 8.3 billion Btu (2,429 MWh-equivalent) in 2024. Its source EUI of 98.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 488,651 kWh of electricity and 66,266 therms of natural gas for the year.
