How has West Office Building's energy performance changed over time?
BuildingCensus holds 7 California disclosures for West Office Building, covering report years 2018–2024. Its ENERGY STAR score went from 42 in 2018 to 90 in 2024 (+48 points). Site EUI moved from 69.9 kBtu/ft² (2018) to 32.6 kBtu/ft² (2024), a 53% decrease. Reported emissions went from 315 tCO₂e to 139 tCO₂e over the same span (down 56%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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 California, 65% 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. West Office Building's 32.6 kBtu/ft² across 66,689 sq ft works out to about 2.2 billion Btu (637 MWh-equivalent) in 2024. The disclosure also reports 479,608 kWh of electricity for the year.
