What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. 24 Royce Rd's 90.6 kBtu/ft² across 13,146 sq ft works out to about 1.2 billion Btu (349 MWh-equivalent) in 2024. The disclosure also reports 58,361 kWh of electricity and 9,915 therms of natural gas for the year.
