The latest disclosures cover 902 benchmarked buildings in Cambridge. 344 Cambridge St's ENERGY STAR score of 91 compares with an average of 66 across the 374 that report a score. Its site EUI of 74.1 kBtu/ft² is about 37% below the average of 117.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 29,577 sq ft, it is about 74% below the average floor area of 114,869 sq ft for those buildings. It was built in 1995, 33 years later than the group's average year built (1962).

How has 344 Cambridge St's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 344 Cambridge St, covering report years 2015–2024. Its ENERGY STAR score went from 85 in 2016 to 91 in 2024 (+6 points); its best year on file was 2022, at 98. Site EUI moved from 79.2 kBtu/ft² (2016) to 74.1 kBtu/ft² (2024), a 6% decrease.
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 344 Cambridge St's 74.1 kBtu/ft² across 29,577 sq ft works out to about 2.2 billion Btu (642 MWh-equivalent) in 2024. Its source EUI of 139.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 306,655 kWh of electricity, 11,449 therms of natural gas and 121 thousand gallons of water for the year.
Which law requires 344 Cambridge St to report its energy use?
