How has MELROSE's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for MELROSE, covering report years 2022–2024. Its ENERGY STAR score went from 7 in 2022 to 5 in 2024 (-2 points); its best year on file was 2022, at 7. Site EUI moved from 158.9 kBtu/ft² (2022) to 161.5 kBtu/ft² (2024), an 2% increase. Reported emissions went from 9,674 tCO₂e to 10,398 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 5 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 5 means the building performs better than about 5% of its national peers. BuildingCensus bands the score into report-card grades; 5 falls in band D — lowest band (1–54). It sits 70 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. MELROSE's 161.5 kBtu/ft² across 983,100 sq ft works out to about 158.8 billion Btu (46,531 MWh-equivalent) in 2024. Its source EUI of 210.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,929,494 kWh of electricity, 1,113,053 therms of natural gas and 178 thousand gallons of water for the year.
