Its site EUI of 33.9 kBtu/ft² is about 40% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.2 kgCO₂e/ft² is about 39% below the group average of 3.6 kgCO₂e/ft².
At 119,691 sq ft, it is about 21% below the average floor area of 151,937 sq ft for those buildings. Its 1982 construction date is close to the group's average year built (1985).

What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. San Mateo Bay Center 2's 33.9 kBtu/ft² across 119,691 sq ft works out to about 4.1 billion Btu (1,189 MWh-equivalent) in 2022. The disclosure also reports 915,237 kWh of electricity and 9,633 therms of natural gas for the year.
