Its site EUI of 13.5 kBtu/ft² is about 38% below the average of 21.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is about half of the group average of 1.4 kgCO₂e/ft².
At 77,262 sq ft, it is about 56% below the average floor area of 173,929 sq ft for those buildings. Its 1990 construction date is close to the group's average year built (1988).

What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. 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. 1580 Zephyr Avenue's 13.5 kBtu/ft² across 77,262 sq ft works out to about 1 billion Btu (306 MWh-equivalent) in 2021. The disclosure also reports 175,764 kWh of electricity and 3,661 therms of natural gas for the year.
Which law requires 1580 Zephyr Avenue to report its energy use?
