Its site EUI of 70.4 kBtu/ft² is about 25% 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 5.0 kgCO₂e/ft² is about 38% above the group average of 3.6 kgCO₂e/ft².
At 21,750 sq ft, it is about 86% below the average floor area of 151,937 sq ft for those buildings. It was built in 2014, 29 years later than the group's average year built (1985).

What does an ENERGY STAR score of 22 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 22 means the building performs better than about 22% of its national peers. BuildingCensus bands the score into report-card grades; 22 falls in band D — lowest band (1–54). It sits 53 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. 900 Villa St's 70.4 kBtu/ft² across 21,750 sq ft works out to about 1.5 billion Btu (449 MWh-equivalent) in 2018. The disclosure also reports 448,489 kWh of electricity for the year.
