Its site EUI of 17.8 kBtu/ft² is about 68% 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 78% below the group average of 3.6 kgCO₂e/ft².
At 81,665 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 1950, 35 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. 13060 - Winton Ave Building's 17.8 kBtu/ft² across 81,665 sq ft works out to about 1.5 billion Btu (426 MWh-equivalent) in 2020. The disclosure also reports 112,241 kWh of electricity and 7,693 therms of natural gas for the year.
