Its ENERGY STAR score went from 56 in 2022 to 43 in 2024 (-13 points); its best year on file was 2022, at 56. Site EUI moved from 57.1 kBtu/ft² (2022) to 56.1 kBtu/ft² (2024), a 2% decrease.

What does an ENERGY STAR score of 43 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 43 means the building performs better than about 43% of its national peers. BuildingCensus bands the score into report-card grades; 43 falls in band D — lowest band (1–54). It sits 32 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. The Chatham's 56.1 kBtu/ft² across 255,961 sq ft works out to about 14.4 billion Btu (4,208 MWh-equivalent) in 2024. Its source EUI of 123.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,648,367 kWh of electricity, 10,821 therms of natural gas and 5,292 thousand gallons of water for the year.
