How does 100 Acorn Park Drive compare with other laboratory buildings in Cambridge?
The latest disclosures cover 88 laboratory buildings in Cambridge, out of 902 buildings citywide. Its site EUI of 123.4 kBtu/ft² is about half of the average of 272.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 155,000 sq ft, it is about 15% below the average floor area of 181,468 sq ft for those buildings. It was built in 2005, 21 years later than the group's average year built (1984). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has 100 Acorn Park Drive's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 100 Acorn Park Drive, covering report years 2015–2024. Its ENERGY STAR score went from 1 in 2015 to 52 in 2023 (+51 points); its best year on file was 2016, at 100. Site EUI moved from 214.0 kBtu/ft² (2015) to 123.4 kBtu/ft² (2024), a 42% decrease. Reported emissions went from 2,500 tCO₂e to 1,326 tCO₂e over the same span (down 47%).
What does a site EUI of 123.4 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. 100 Acorn Park Drive's 123.4 kBtu/ft² across 155,000 sq ft works out to about 19.1 billion Btu (5,606 MWh-equivalent) in 2024. Its source EUI of 313.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,764,933 kWh of electricity, 28,674 therms of natural gas and 740 thousand gallons of water for the year.
Which law requires 100 Acorn Park Drive to report its energy use?
100 Acorn Park Drive 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:B1016:2024). 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).
