What does an ENERGY STAR score of 45 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 45 means the building performs better than about 45% of its national peers. BuildingCensus bands the score into report-card grades; 45 falls in band D — lowest band (1–54). It sits 30 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. 41 Madison Ave LP's 92.5 kBtu/ft² across 562,152 sq ft works out to about 52 billion Btu (15,239 MWh-equivalent) in 2024. Its source EUI of 168.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,940,329 kWh of electricity, 18,481 therms of natural gas and 8,474 thousand gallons of water for the year.
