What does a site EUI of 2594.5 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. 205 Alewife Brook Parkway's 2594.5 kBtu/ft² across 28,054 sq ft works out to about 72.8 billion Btu (21,332 MWh-equivalent) in 2024. Its source EUI of 3705.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,611,229 kWh of electricity, 570,513 therms of natural gas and 21,787 thousand gallons of water for the year.
Which law requires 205 Alewife Brook Parkway to report its energy use?
205 Alewife Brook Parkway 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:B1465:2024). 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).
