How does 1414 Massachusetts Avenue compare with other office buildings in Cambridge?
The latest disclosures cover 117 office buildings in Cambridge, out of 902 buildings citywide. 1414 Massachusetts Avenue's ENERGY STAR score of 82 compares with an average of 64 across the 94 that report a score; it scores higher than 68% of them and lower than 29%. Its site EUI of 51.0 kBtu/ft² is about 35% below the average of 78.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 82,345 sq ft, it is about 32% below the average floor area of 121,167 sq ft for those buildings. It was built in 1873, 92 years earlier 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 1414 Massachusetts Avenue's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1414 Massachusetts Avenue, covering report years 2015–2024. Its ENERGY STAR score went from 60 in 2015 to 82 in 2024 (+22 points). Site EUI moved from 79.0 kBtu/ft² (2015) to 51.0 kBtu/ft² (2024), a 35% decrease. Reported emissions went from 434 tCO₂e to 268 tCO₂e over the same span (down 38%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 1414 Massachusetts Avenue's 51.0 kBtu/ft² across 82,345 sq ft works out to about 4.2 billion Btu (1,231 MWh-equivalent) in 2024. Its source EUI of 104.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 696,676 kWh of electricity and 18,192 therms of natural gas for the year.
Which law requires 1414 Massachusetts Avenue to report its energy use?
1414 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:B1301:2024). 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).
