What does an ENERGY STAR score of 24 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 24 means the building performs better than about 24% of its national peers. BuildingCensus bands the score into report-card grades; 24 falls in band D — lowest band (1–54). It sits 51 points below 75, the threshold for ENERGY STAR certification. In Cambridge, 50% 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. 632 Massachusetts Avenue's 60.2 kBtu/ft² across 197,283 sq ft works out to about 11.9 billion Btu (3,481 MWh-equivalent) in 2024. Its source EUI of 112.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,617,788 kWh of electricity, 63,579 therms of natural gas and 44 thousand gallons of water for the year.

Which law requires 632 Massachusetts Avenue to report its energy use?

632 Massachusetts Avenue reports under BEUDO, the legal basis of Cambridge's Building Energy Use Disclosure Ordinance (BEUDO), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record cambridge:B1561:2024). Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).
