Its site EUI of 56.3 kBtu/ft² is roughly in line with the average of 56.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 112,985 sq ft, it is about 15% below the average floor area of 132,415 sq ft for those buildings. It was built in 2004, 31 years later than the group's average year built (1973). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has 29 Garden Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 29 Garden Street, covering report years 2015–2024. Its ENERGY STAR score went from 39 in 2015 to 61 in 2024 (+22 points). Site EUI moved from 73.9 kBtu/ft² (2015) to 56.3 kBtu/ft² (2024), a 24% decrease. Reported emissions went from 509 tCO₂e to 382 tCO₂e over the same span (down 25%).
What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. 29 Garden Street's 56.3 kBtu/ft² across 112,985 sq ft works out to about 6.4 billion Btu (1,864 MWh-equivalent) in 2024. Its source EUI of 95.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 680,476 kWh of electricity, 40,423 therms of natural gas and 1,856 thousand gallons of water for the year.
