How does 1815 MASSACHUSETTS AVE compare with other college/university buildings in Cambridge?
The latest disclosures cover 203 college/university buildings in Cambridge, out of 902 buildings citywide. Its site EUI of 70.3 kBtu/ft² is about half of the average of 154.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 231,590 sq ft, it is about 139% above the average floor area of 96,964 sq ft for those buildings. It was built in 1945, 4 years earlier than the group's average year built (1949). Across all 24 jurisdictions BuildingCensus covers, the 2,113 college/university buildings average an ENERGY STAR score of 68 and a site EUI of 98.7 kBtu/ft².
How has 1815 MASSACHUSETTS AVE's energy performance changed over time?
BuildingCensus holds 7 Cambridge disclosures for 1815 MASSACHUSETTS AVE, covering report years 2015–2021. Site EUI moved from 86.3 kBtu/ft² (2015) to 70.3 kBtu/ft² (2021), a 19% decrease. Reported emissions went from 1,287 tCO₂e to 1,034 tCO₂e over the same span (down 20%).
What does a site EUI of 70.3 kBtu/ft² mean?
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. 1815 MASSACHUSETTS AVE's 70.3 kBtu/ft² across 231,590 sq ft works out to about 16.3 billion Btu (4,771 MWh-equivalent) in 2021. Its source EUI of 140.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,583,501 kWh of electricity and 74,700 therms of natural gas for the year.
Which law requires 1815 MASSACHUSETTS AVE to report its energy use?
1815 MASSACHUSETTS AVE 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 2021 disclosure (source record cambridge:B1728:2021). 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).
