How does 80 Sparks St. 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. 80 Sparks St.'s ENERGY STAR score of 92 compares with an average of 60 across the 38 that report a score; it scores higher than 87% of them and lower than 8%. Its site EUI of 20.0 kBtu/ft² is about 68% below the average of 62.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 31,615 sq ft, it is about half of the average floor area of 61,739 sq ft for those buildings. It was built in 1859, 97 years earlier 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 80 Sparks St.'s energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 80 Sparks St., covering report years 2015–2024. Its ENERGY STAR score went from 31 in 2015 to 92 in 2024 (+61 points). Site EUI moved from 90.4 kBtu/ft² (2015) to 20.0 kBtu/ft² (2024), a 78% decrease. Reported emissions went from 168 tCO₂e to 46 tCO₂e over the same span (down 73%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 falls in band A — high performer (85–100). 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. 80 Sparks St.'s 20.0 kBtu/ft² across 31,615 sq ft works out to about 0.6 billion Btu (185 MWh-equivalent) in 2024. Its source EUI of 55.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 182,103 kWh of electricity, 125 therms of natural gas and 197 thousand gallons of water for the year.
Which law requires 80 Sparks St. to report its energy use?
80 Sparks 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:B1439:2024). 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).
