What does an ENERGY STAR score of 20 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 20 means the building performs better than about 20% of its national peers. BuildingCensus bands the score into report-card grades; 20 falls in band D — lowest band (1–54). It sits 55 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. 79 Walker Street's 158.3 kBtu/ft² across 26,242 sq ft works out to about 4.2 billion Btu (1,217 MWh-equivalent) in 2022. Its source EUI of 264.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 429,963 kWh of electricity for the year.
