Its site EUI of 132.7 kBtu/ft² is about 69% above the average of 78.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 79,616 sq ft, it is about 34% below the average floor area of 121,167 sq ft for those buildings. It was built in 1984, 19 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 11 Cambridge Ctr's energy performance changed over time?
BuildingCensus holds 2 Cambridge disclosures for 11 Cambridge Ctr, covering report years 2015–2016. Its ENERGY STAR score went from 83 in 2015 to 53 in 2016 (-30 points); its best year on file was 2015, at 83. Site EUI moved from 355.5 kBtu/ft² (2015) to 132.7 kBtu/ft² (2016), a 63% decrease. Reported emissions went from 2,170 tCO₂e to 792 tCO₂e over the same span (down 64%).
What does an ENERGY STAR score of 53 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 53 means the building performs better than about 53% of its national peers. BuildingCensus bands the score into report-card grades; 53 falls in band D — lowest band (1–54). It sits 22 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. 11 Cambridge Ctr's 132.7 kBtu/ft² across 79,616 sq ft works out to about 10.6 billion Btu (3,096 MWh-equivalent) in 2016. Its source EUI of 416.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,095,763 kWh of electricity and 2,294 thousand gallons of water for the year.
Which law requires 11 Cambridge Ctr to report its energy use?
11 Cambridge Ctr 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 2016 disclosure (source record cambridge:B1879:2016). 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).
