How has 185 / 205 Bent St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 185 / 205 Bent St, covering report years 2015–2024. Site EUI moved from 970.9 kBtu/ft² (2016) to 602.2 kBtu/ft² (2024), a 38% decrease. Reported emissions went from 2,043 tCO₂e to 999 tCO₂e over the same span (down 51%).
What does a site EUI of 602.2 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. 185 / 205 Bent St's 602.2 kBtu/ft² across 28,100 sq ft works out to about 16.9 billion Btu (4,959 MWh-equivalent) in 2024. Its source EUI of 1686.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,053,859 kWh of electricity and 90 thousand gallons of water for the year.
Which law requires 185 / 205 Bent St to report its energy use?
185 / 205 Bent 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:B1557:2024). 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).
