Its site EUI of 33.1 kBtu/ft² is about 41% 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 2.2 kgCO₂e/ft² is about 39% below the group average of 3.6 kgCO₂e/ft².
At 114,489 sq ft, it is about 25% below the average floor area of 151,937 sq ft for those buildings. It was built in 2002, 17 years later 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 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 900 Concar Drive's 33.1 kBtu/ft² across 114,489 sq ft works out to about 3.8 billion Btu (1,111 MWh-equivalent) in 2018. The disclosure also reports 836,967 kWh of electricity and 9,634 therms of natural gas for the year.
Which law requires 900 Concar Drive to report its energy use?
