What does an ENERGY STAR score of 63 mean?

BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 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. Marseilles Apartments's 62.2 kBtu/ft² across 168,140 sq ft works out to about 10.5 billion Btu (3,065 MWh-equivalent) in 2024. Its source EUI of 93.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 791,308 kWh of electricity, 76,238 therms of natural gas and 5,827 thousand gallons of water for the year.
