How has 119 Windsor St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 119 Windsor St, covering report years 2015–2024. Its ENERGY STAR score went from 35 in 2015 to 26 in 2024 (-9 points); its best year on file was 2015, at 35. Site EUI moved from 108.1 kBtu/ft² (2015) to 132.0 kBtu/ft² (2024), an 22% increase. Reported emissions went from 455 tCO₂e to 512 tCO₂e over the same span (up 13%).
What does an ENERGY STAR score of 26 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 26 means the building performs better than about 26% of its national peers. BuildingCensus bands the score into report-card grades; 26 falls in band D — lowest band (1–54). It sits 49 points below 75, the threshold for ENERGY STAR certification. In Cambridge, 50% of scored buildings are at 75 or above.
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. 119 Windsor St's 132.0 kBtu/ft² across 64,703 sq ft works out to about 8.5 billion Btu (2,503 MWh-equivalent) in 2024. Its source EUI of 221.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 901,344 kWh of electricity, 54,641 therms of natural gas and 678 thousand gallons of water for the year.
Which law requires 119 Windsor St to report its energy use?
119 Windsor 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:B1547:2024). 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).
