How has 247 Garden Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 247 Garden Street, covering report years 2015–2024. Its ENERGY STAR score went from 100 in 2015 to 86 in 2024 (-14 points); its best year on file was 2015, at 100. Site EUI moved from 21.5 kBtu/ft² (2015) to 41.8 kBtu/ft² (2024), an 94% increase. Reported emissions went from 144 tCO₂e to 319 tCO₂e over the same span (up 121%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. 247 Garden Street's 41.8 kBtu/ft² across 117,581 sq ft works out to about 4.9 billion Btu (1,440 MWh-equivalent) in 2024. Its source EUI of 89.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 888,445 kWh of electricity, 18,785 therms of natural gas and 6,331 thousand gallons of water for the year.
