What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 20 Grand Avenue's 28.9 kBtu/ft² across 92,856 sq ft works out to about 2.7 billion Btu (786 MWh-equivalent) in 2024. Its source EUI of 55.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 388,400 kWh of electricity, 13,590 therms of natural gas and 2,715 thousand gallons of water for the year.
