How does 229 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 72.2 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 191,190 sq ft, it is about twice the average floor area of 96,964 sq ft for those buildings. It was built in 2002, 53 years later 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 229 VASSAR ST's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 229 VASSAR ST, covering report years 2015–2024. Site EUI moved from 128.4 kBtu/ft² (2015) to 72.2 kBtu/ft² (2024), a 44% decrease. Reported emissions went from 1,664 tCO₂e to 884 tCO₂e over the same span (down 47%).
What does a site EUI of 72.2 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. 229 VASSAR ST's 72.2 kBtu/ft² across 191,190 sq ft works out to about 13.8 billion Btu (4,046 MWh-equivalent) in 2024. Its source EUI of 126.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,795,730 kWh of electricity and 4,432 thousand gallons of water for the year.
Which law requires 229 VASSAR ST to report its energy use?
229 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:B1568:2024). 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).
