Its site EUI of 80.5 kBtu/ft² is about 43% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.2 kgCO₂e/ft² is about 44% above the group average of 3.6 kgCO₂e/ft².
At 143,292 sq ft, it is roughly in line with the average floor area of 151,937 sq ft for those buildings. It was built in 1988, 3 years later than the group's average year built (1985).

What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 falls in band B — above median (70–84). 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. 999 Brannan - New's 80.5 kBtu/ft² across 143,292 sq ft works out to about 11.5 billion Btu (3,381 MWh-equivalent) in 2018. The disclosure also reports 2,189,865 kWh of electricity and 40,584 therms of natural gas for the year.
