What does an ENERGY STAR score of 43 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 43 means the building performs better than about 43% of its national peers. BuildingCensus bands the score into report-card grades; 43 falls in band D — lowest band (1–54). It sits 32 points below 75, the threshold for ENERGY STAR certification. In Boston, 52% 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. 9-15 Egremont Rd's 87.3 kBtu/ft² across 20,800 sq ft works out to about 1.8 billion Btu (532 MWh-equivalent) in 2024.
