What does an ENERGY STAR score of 42 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 42 means the building performs better than about 42% of its national peers. BuildingCensus bands the score into report-card grades; 42 falls in band D — lowest band (1–54). It sits 33 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. 146 S 4th Street's 51.4 kBtu/ft² across 107,986 sq ft works out to about 5.6 billion Btu (1,627 MWh-equivalent) in 2023. Its source EUI of 117.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,156,189 kWh of electricity and 16,078 therms of natural gas for the year.
