Its site EUI of 56.3 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 3.8 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².
At 137,068 sq ft, it is roughly in line with the average floor area of 151,937 sq ft for those buildings. It was built in 1919, 66 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 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 351 California Street's 56.3 kBtu/ft² across 137,068 sq ft works out to about 7.7 billion Btu (2,262 MWh-equivalent) in 2018. The disclosure also reports 1,483,911 kWh of electricity and 10,636 therms of natural gas for the year.
