Its site EUI of 79.2 kBtu/ft² is roughly in line with the average of 78.7 kBtu/ft².
At 85,470 sq ft, it is about 29% below the average floor area of 121,167 sq ft for those buildings. It was built in 1974, 9 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 1033 Massachusetts Avenue's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1033 Massachusetts Avenue, covering report years 2015–2024. Its ENERGY STAR score was 76 in both 2015 and 2024. Site EUI moved from 78.9 kBtu/ft² (2015) to 79.2 kBtu/ft² (2024), an 0% increase. Reported emissions went from 441 tCO₂e to 425 tCO₂e over the same span (down 4%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. 1033 Massachusetts Avenue's 79.2 kBtu/ft² across 85,470 sq ft works out to about 6.8 billion Btu (1,984 MWh-equivalent) in 2024. Its source EUI of 153.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,007,319 kWh of electricity, 33,326 therms of natural gas and 657 thousand gallons of water for the year.
Which law requires 1033 Massachusetts Avenue to report its energy use?
1033 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:B1281:2024). 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).
