How does Hewlett Building compare with other college/university buildings in California?
The latest disclosures cover 497 college/university buildings in California, out of 40,029 buildings citywide. Its site EUI of 39.5 kBtu/ft² is about half of the average of 79.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.3 kgCO₂e/ft² is about half of the group average of 4.8 kgCO₂e/ft².
At 52,263 sq ft, it is about 91% below the average floor area of 569,516 sq ft for those buildings. It was built in 1985, 17 years later than the group's average year built (1969). Across all 24 jurisdictions BuildingCensus covers, the 2,113 college/university buildings average an ENERGY STAR score of 68 and a site EUI of 98.7 kBtu/ft².
What does a site EUI of 39.5 kBtu/ft² mean?
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. Hewlett Building's 39.5 kBtu/ft² across 52,263 sq ft works out to about 2.1 billion Btu (605 MWh-equivalent) in 2024. The disclosure also reports 356,611 kWh of electricity for the year.
Which law requires Hewlett Building to report its energy use?
