What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Wallack - 45 East 85th Street's 58.0 kBtu/ft² across 109,200 sq ft works out to about 6.3 billion Btu (1,856 MWh-equivalent) in 2024.

The disclosure also reports 505,851 kWh of electricity, 1,188 therms of natural gas and 2,234 thousand gallons of water for the year.
