How does 44 Linnaean Street compare with other K-12 school buildings in Cambridge?
The latest disclosures cover 45 K-12 school buildings in Cambridge, out of 902 buildings citywide. 44 Linnaean Street's ENERGY STAR score of 84 compares with an average of 60 across the 38 that report a score; it scores higher than 71% of them and lower than 26%. Its site EUI of 45.1 kBtu/ft² is about 28% below the average of 62.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 78,732 sq ft, it is about 28% above the average floor area of 61,739 sq ft for those buildings. It was built in 1960, 4 years later than the group's average year built (1956). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
How has 44 Linnaean Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 44 Linnaean Street, covering report years 2015–2024. Its ENERGY STAR score went from 79 in 2015 to 84 in 2024 (+5 points); its best year on file was 2020, at 89. Site EUI moved from 54.5 kBtu/ft² (2015) to 45.1 kBtu/ft² (2024), a 17% decrease. Reported emissions went from 301 tCO₂e to 206 tCO₂e over the same span (down 32%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 44 Linnaean Street's 45.1 kBtu/ft² across 78,732 sq ft works out to about 3.6 billion Btu (1,041 MWh-equivalent) in 2024. Its source EUI of 66.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 257,045 kWh of electricity, 26,772 therms of natural gas and 337 thousand gallons of water for the year.
Which law requires 44 Linnaean Street to report its energy use?
44 Linnaean Street 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:B1058:2024). 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).
