How has 3220 El Camino Real's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 3220 El Camino Real, covering report years 2018–2024. Its ENERGY STAR score went from 72 in 2020 to 93 in 2024 (+21 points).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 3220 El Camino Real's 36.1 kBtu/ft² across 62,850 sq ft works out to about 2.3 billion Btu (665 MWh-equivalent) in 2024. The disclosure also reports 400,425 kWh of electricity and 7,520 therms of natural gas for the year.
