How has 255 W Tasman Dr's energy performance changed over time?
BuildingCensus holds 7 San José disclosures for 255 W Tasman Dr, covering report years 2018–2024. Its ENERGY STAR score went from 92 in 2022 to 60 in 2024 (-32 points); its best year on file was 2022, at 92. Site EUI moved from 17.1 kBtu/ft² (2020) to 58.4 kBtu/ft² (2024), an 242% increase. Reported emissions went from 401 tCO₂e to 678 tCO₂e over the same span (up 69%).
What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 points below 75, the threshold for ENERGY STAR certification. In San José, 69% 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. 255 W Tasman Dr's 58.4 kBtu/ft² across 181,249 sq ft works out to about 10.6 billion Btu (3,102 MWh-equivalent) in 2024. Its source EUI of 146.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,578,944 kWh of electricity, 17,794 therms of natural gas and 5,369 thousand gallons of water for the year.
