Its site EUI of 12.9 kBtu/ft² is about 77% 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 0.8 kgCO₂e/ft² is about 77% below the group average of 3.6 kgCO₂e/ft².
At 170,378 sq ft, it is about 12% above the average floor area of 151,937 sq ft for those buildings. It was built in 1990, 5 years later than the group's average year built (1985).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. 1 Harrison- Sobrato Account's 12.9 kBtu/ft² across 170,378 sq ft works out to about 2.2 billion Btu (644 MWh-equivalent) in 2024. The disclosure also reports 559,206 kWh of electricity and 2,879 therms of natural gas for the year.
