How has Hoover Tower's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Hoover Tower, covering report years 2019–2024. Site EUI moved from 39.4 kBtu/ft² (2019) to 17.3 kBtu/ft² (2024), a 56% decrease. Reported emissions went from 230 tCO₂e to 107 tCO₂e over the same span (down 54%).
What does a site EUI of 17.3 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. Hoover Tower's 17.3 kBtu/ft² across 92,964 sq ft works out to about 1.6 billion Btu (471 MWh-equivalent) in 2024. The disclosure also reports 471,563 kWh of electricity for the year.
Which law requires Hoover Tower to report its energy use?
