How has St. Ambrose Parish's energy performance changed over time?
BuildingCensus holds 4 Berkeley disclosures for St. Ambrose Parish, covering report years 2022–2025. Site EUI moved from 6.1 kBtu/ft² (2022) to 7.0 kBtu/ft² (2025), an 15% increase.
What does a site EUI of 7.0 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. St. Ambrose Parish's 7.0 kBtu/ft² across 18,616 sq ft works out to about 0.1 billion Btu (38 MWh-equivalent) in 2025. Its source EUI of 11.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 11,160 kWh of electricity and 928 therms of natural gas for the year.
Which law requires St. Ambrose Parish to report its energy use?
St. Ambrose Parish reports under BESO (BMC Chapter 19.81), the legal basis of Berkeley's Building Emissions Saving Ordinance, which publishes each covered building's annual benchmarking results.
