Onni 800 Wilshire Owner Lp's ENERGY STAR score of 84 compares with an average of 75 across the 4,912 that report a score; it scores higher than 50% of them and lower than 48%. Its site EUI of 41.8 kBtu/ft² is about 26% 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 2.9 kgCO₂e/ft² is about 19% below the group average of 3.6 kgCO₂e/ft².
At 249,008 sq ft, it is about 64% above the average floor area of 151,937 sq ft for those buildings. It was built in 1972, 13 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 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). 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. Onni 800 Wilshire Owner Lp's 41.8 kBtu/ft² across 249,008 sq ft works out to about 10.4 billion Btu (3,050 MWh-equivalent) in 2018. The disclosure also reports 2,831,125 kWh of electricity and 7,547 therms of natural gas for the year.
