Its site EUI of 104.5 kBtu/ft² is about 33% above the average of 78.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 34,842 sq ft, it is about 71% below the average floor area of 121,167 sq ft for those buildings. It was built in 1973, 8 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 77 Fawcett Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 77 Fawcett Street, covering report years 2015–2024. Its ENERGY STAR score went from 3 in 2017 to 11 in 2024 (+8 points). Site EUI moved from 131.1 kBtu/ft² (2017) to 104.5 kBtu/ft² (2024), a 20% decrease.
What does an ENERGY STAR score of 11 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 11 means the building performs better than about 11% of its national peers. BuildingCensus bands the score into report-card grades; 11 falls in band D — lowest band (1–54). It sits 64 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. 77 Fawcett Street's 104.5 kBtu/ft² across 34,842 sq ft works out to about 3.6 billion Btu (1,067 MWh-equivalent) in 2024. Its source EUI of 237.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 747,932 kWh of electricity, 10,906 therms of natural gas and 49 thousand gallons of water for the year.
Which law requires 77 Fawcett Street to report its energy use?
77 Fawcett Street 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:B1665:2024). 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).
