How does 2300 Polvorosa Ave compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. 2300 Polvorosa Ave's ENERGY STAR score of 100 compares with an average of 75 across the 4,912 that report a score; it scores higher than 91% of them. Its site EUI of 6.0 kBtu/ft² is about 89% 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 0.4 kgCO₂e/ft² is about 90% below the group average of 3.6 kgCO₂e/ft².
At 75,414 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 1973, 12 years earlier than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 2300 Polvorosa Ave's 6.0 kBtu/ft² across 75,414 sq ft works out to about 0.5 billion Btu (133 MWh-equivalent) in 2019. The disclosure also reports 103,785 kWh of electricity and 784 therms of natural gas for the year.
