What does a site EUI of 60.2 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. 150 Franklin St's 60.2 kBtu/ft² across 6,652 sq ft works out to about 0.4 billion Btu (117 MWh-equivalent) in 2024. Its source EUI of 89.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 29,271 kWh of electricity and 3,009 therms of natural gas for the year.
Which law requires 150 Franklin St to report its energy use?
150 Franklin 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:B1799:2024). 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).
