What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 1630 Undercliff Ave - 38870's 64.0 kBtu/ft² across 67,100 sq ft works out to about 4.3 billion Btu (1,259 MWh-equivalent) in 2024.

The disclosure also reports 213,673 kWh of electricity, 35,625 therms of natural gas and 3,787 thousand gallons of water for the year.
