Its site EUI of 19.8 kBtu/ft² is roughly in line with the average of 21.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.3 kgCO₂e/ft² is roughly in line with the group average of 1.4 kgCO₂e/ft².
At 97,000 sq ft, it is about 44% below the average floor area of 173,929 sq ft for those buildings. It was built in 1970, 18 years earlier than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².
What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 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. 9419 Mason Partners Llc's 19.8 kBtu/ft² across 97,000 sq ft works out to about 1.9 billion Btu (563 MWh-equivalent) in 2024. The disclosure also reports 547,977 kWh of electricity for the year.
