What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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 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. 45 Burnett St's 30.1 kBtu/ft² across 47,124 sq ft works out to about 1.4 billion Btu (416 MWh-equivalent) in 2024. The disclosure also reports 312,655 kWh of electricity and 3,525 therms of natural gas for the year.
