How has 334 Harvard Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 334 Harvard Street, covering report years 2015–2024. Its ENERGY STAR score went from 75 in 2016 to 89 in 2024 (+14 points); its best year on file was 2018, at 100. Site EUI moved from 82.4 kBtu/ft² (2016) to 59.9 kBtu/ft² (2024), a 27% decrease.
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. 334 Harvard Street's 59.9 kBtu/ft² across 44,724 sq ft works out to about 2.7 billion Btu (785 MWh-equivalent) in 2024. Its source EUI of 109.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 350,977 kWh of electricity, 14,794 therms of natural gas and 1,275 thousand gallons of water for the year.
