What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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 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. 49 Norfolk St's 57.1 kBtu/ft² across 36,416 sq ft works out to about 2.1 billion Btu (609 MWh-equivalent) in 2024. The disclosure also reports 218,346 kWh of electricity and 13,351 therms of natural gas for the year.
