Its site EUI of 51.6 kBtu/ft² is roughly in line with 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 3.7 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².
At 55,690 sq ft, it is about 63% below the average floor area of 151,937 sq ft for those buildings. Its 1986 construction date is close to 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 51 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 51 means the building performs better than about 51% of its national peers. BuildingCensus bands the score into report-card grades; 51 falls in band D — lowest band (1–54). It sits 24 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. Square One Office Plaza's 51.6 kBtu/ft² across 55,690 sq ft works out to about 2.9 billion Btu (842 MWh-equivalent) in 2018. The disclosure also reports 864,660 kWh of electricity and 8 therms of natural gas for the year.
