The latest disclosures cover 203 college/university buildings in Cambridge, out of 902 buildings citywide. Its site EUI of 72.8 kBtu/ft² is about half of the average of 154.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 45,952 sq ft, it is about half of the average floor area of 96,964 sq ft for those buildings. It was built in 1968, 19 years later than the group's average year built (1949). Across all 24 jurisdictions BuildingCensus covers, the 2,113 college/university buildings average an ENERGY STAR score of 68 and a site EUI of 98.7 kBtu/ft².
How has 14 Appian way's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 14 Appian way, covering report years 2015–2024. Site EUI moved from 81.0 kBtu/ft² (2015) to 72.8 kBtu/ft² (2024), a 10% decrease. Reported emissions went from 232 tCO₂e to 208 tCO₂e over the same span (down 11%).
What does a site EUI of 72.8 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. 14 Appian way's 72.8 kBtu/ft² across 45,952 sq ft works out to about 3.3 billion Btu (980 MWh-equivalent) in 2024. Its source EUI of 135.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 457,394 kWh of electricity, 17,858 therms of natural gas and 443 thousand gallons of water for the year.
Which law requires 14 Appian way to report its energy use?
14 Appian way 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:B1197:2024). 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).
