How does 70 VASSAR ST (REAR) 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 301.9 kBtu/ft² is about twice the average of 154.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 63,579 sq ft, it is about 34% below the average floor area of 96,964 sq ft for those buildings. It was built in 1928, 21 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 70 VASSAR ST (REAR)'s energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 70 VASSAR ST (REAR), covering report years 2015–2024. Site EUI moved from 338.6 kBtu/ft² (2015) to 301.9 kBtu/ft² (2024), a 11% decrease. Reported emissions went from 1,358 tCO₂e to 1,247 tCO₂e over the same span (down 8%).
What does a site EUI of 301.9 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. 70 VASSAR ST (REAR)'s 301.9 kBtu/ft² across 63,579 sq ft works out to about 19.2 billion Btu (5,625 MWh-equivalent) in 2024. Its source EUI of 490.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,875,103 kWh of electricity, 67 therms of natural gas and 644 thousand gallons of water for the year.
Which law requires 70 VASSAR ST (REAR) to report its energy use?
70 VASSAR ST (REAR) 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:B1491:2024). 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).
