What does a site EUI of 66.7 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 Cambridge Side Place's 66.7 kBtu/ft² across 396,082 sq ft works out to about 26.4 billion Btu (7,743 MWh-equivalent) in 2024. Its source EUI of 181.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 7,361,958 kWh of electricity, 13,080 therms of natural gas and 8,168 thousand gallons of water for the year.
Which law requires 100 Cambridge Side Place to report its energy use?
100 Cambridge Side Place 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:B1089:2024). 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).
