How has 11 Garden Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 11 Garden Street, covering report years 2015–2024. Its ENERGY STAR score was 1 in both 2019 and 2024.

What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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 Garden Street's 403.0 kBtu/ft² across 5,000 sq ft works out to about 2 billion Btu (591 MWh-equivalent) in 2024. Its source EUI of 556.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 111,274 kWh of electricity, 16,355 therms of natural gas and 486 thousand gallons of water for the year.
Which law requires 11 Garden Street to report its energy use?
11 Garden 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.
