Diablo Business Park (3440-3464)'s ENERGY STAR score of 90 compares with an average of 68 across the 2,227 that report a score; it scores higher than 66% of them and lower than 32%. Its site EUI of 15.9 kBtu/ft² is about 27% 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 0.8 kgCO₂e/ft² is about 43% below the group average of 1.4 kgCO₂e/ft².

At 50,555 sq ft, it is about 71% below the average floor area of 173,929 sq ft for those buildings. Its 1985 construction date is close to the group's average year built (1988).

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. Diablo Business Park (3440-3464)'s 15.9 kBtu/ft² across 50,555 sq ft works out to about 0.8 billion Btu (236 MWh-equivalent) in 2020. The disclosure also reports 111,142 kWh of electricity and 2,955 therms of natural gas for the year.
