How has 111 Plympton St's energy performance changed over time?
BuildingCensus holds 7 Cambridge disclosures for 111 Plympton St, covering report years 2018–2024. Site EUI moved from 50.7 kBtu/ft² (2020) to 85.2 kBtu/ft² (2024), an 68% increase.
What does a site EUI of 85.2 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. 111 Plympton St's 85.2 kBtu/ft² across 226,500 sq ft works out to about 19.3 billion Btu (5,656 MWh-equivalent) in 2024. Its source EUI of 134.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,593,311 kWh of electricity, 4,075 therms of natural gas and 3,806 thousand gallons of water for the year.
Which law requires 111 Plympton St to report its energy use?
111 Plympton 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:B1282:2024). 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).
