How has 105 MASSACHUSETTS AVE (REAR)'s energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 105 MASSACHUSETTS AVE (REAR), covering report years 2015–2024. Site EUI moved from 409.5 kBtu/ft² (2015) to 531.7 kBtu/ft² (2024), an 30% increase. Reported emissions went from 4,993 tCO₂e to 6,358 tCO₂e over the same span (up 27%).
What does a site EUI of 531.7 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. 105 MASSACHUSETTS AVE (REAR)'s 531.7 kBtu/ft² across 183,169 sq ft works out to about 97.4 billion Btu (28,542 MWh-equivalent) in 2024. Its source EUI of 835.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,216,241 kWh of electricity, 1,729 therms of natural gas and 1,552 thousand gallons of water for the year.
Which law requires 105 MASSACHUSETTS AVE (REAR) to report its energy use?
105 MASSACHUSETTS AVE (REAR) 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:B1527:2024). 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).
