What does an ENERGY STAR score of 30 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 30 means the building performs better than about 30% of its national peers. BuildingCensus bands the score into report-card grades; 30 falls in band D — lowest band (1–54). It sits 45 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. CC NEW - 235 WEST 145 STREET 2020's 81.0 kBtu/ft² across 32,669 sq ft works out to about 2.6 billion Btu (776 MWh-equivalent) in 2023.

The disclosure also reports 190,326 kWh of electricity, 19,979 therms of natural gas and 1,593 thousand gallons of water for the year.
