How has 105 Broadway (10 Cambridge Center)'s energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 105 Broadway (10 Cambridge Center), covering report years 2015–2024. Its ENERGY STAR score went from 49 in 2015 to 87 in 2024 (+38 points); its best year on file was 2022, at 94. Site EUI moved from 108.4 kBtu/ft² (2015) to 78.6 kBtu/ft² (2024), a 27% decrease. Reported emissions went from 1,397 tCO₂e to 966 tCO₂e over the same span (down 31%).
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 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. 105 Broadway (10 Cambridge Center)'s 78.6 kBtu/ft² across 185,196 sq ft works out to about 14.6 billion Btu (4,266 MWh-equivalent) in 2024. Its source EUI of 178.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,962,125 kWh of electricity, 44,417 therms of natural gas and 1,618 thousand gallons of water for the year.
