Its emissions intensity of 4.2 kgCO₂e/ft² is about 12% below the group average of 4.8 kgCO₂e/ft².
At 2,020,351 sq ft, it is about 255% above the average floor area of 569,516 sq ft for those buildings. It was built in 1913, 55 years earlier 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.
How has Humboldt State University's energy performance changed over time?
BuildingCensus holds 4 California disclosures for Humboldt State University, covering report years 2021–2024. Site EUI moved from 57.8 kBtu/ft² (2021) to 72.9 kBtu/ft² (2024), an 26% increase. Reported emissions went from 7,079 tCO₂e to 8,525 tCO₂e over the same span (up 20%).
What does a site EUI of 72.9 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. Humboldt State University's 72.9 kBtu/ft² across 2,020,351 sq ft works out to about 147.3 billion Btu (43,165 MWh-equivalent) in 2024. The disclosure also reports 13,028,074 kWh of electricity and 1,049,598 therms of natural gas for the year.
Which law requires Humboldt State University to report its energy use?
Humboldt State University reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:17806272:2024).
