What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 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. 26-28 Thomson Pl's 66.6 kBtu/ft² across 28,500 sq ft works out to about 1.9 billion Btu (556 MWh-equivalent) in 2024. The disclosure also reports 284,616 kWh of electricity for the year.
