Its site EUI of 26.7 kBtu/ft² is about 22% below the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.5 kgCO₂e/ft² is about 29% below the group average of 2.1 kgCO₂e/ft².
At 41,866 sq ft, it is about 72% below the average floor area of 150,919 sq ft for those buildings. It was built in 1977, 11 years earlier than the group's average year built (1988).

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. 17271 Mcfadden's 26.7 kBtu/ft² across 41,866 sq ft works out to about 1.1 billion Btu (328 MWh-equivalent) in 2023. The disclosure also reports 39,813 kWh of electricity and 9,754 therms of natural gas for the year.
