How does 106 VASSAR ST 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 51.8 kBtu/ft² is about 66% below the average of 154.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 34,428 sq ft, it is about 64% below the average floor area of 96,964 sq ft for those buildings. Its 1948 construction date is close to 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 106 VASSAR ST's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 106 VASSAR ST, covering report years 2015–2024. Site EUI moved from 227.5 kBtu/ft² (2015) to 51.8 kBtu/ft² (2024), a 77% decrease. Reported emissions went from 541 tCO₂e to 119 tCO₂e over the same span (down 78%).
What does a site EUI of 51.8 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. 106 VASSAR ST's 51.8 kBtu/ft² across 34,428 sq ft works out to about 1.8 billion Btu (523 MWh-equivalent) in 2024. Its source EUI of 64.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 16,449 kWh of electricity for the year.
Which law requires 106 VASSAR ST to report its energy use?
106 VASSAR ST 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:B1578:2024). 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).
