How has 300 Bent Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 300 Bent Street, covering report years 2015–2024. Site EUI moved from 1.1 kBtu/ft² (2015) to 8.2 kBtu/ft² (2024), an 645% increase. Reported emissions went from 8 tCO₂e to 53 tCO₂e over the same span (up 601%).
What does a site EUI of 8.2 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. 300 Bent Street's 8.2 kBtu/ft² across 90,000 sq ft works out to about 0.7 billion Btu (216 MWh-equivalent) in 2024. Its source EUI of 22.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 215,736 kWh of electricity and 79 thousand gallons of water for the year.
Which law requires 300 Bent Street to report its energy use?
300 Bent Street 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:B1558:2024). 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).
