How has 5901 Optical Ct's energy performance changed over time?
BuildingCensus holds 7 San José disclosures for 5901 Optical Ct, covering report years 2018–2024. Site EUI moved from 0.9 kBtu/ft² (2020) to 81.5 kBtu/ft² (2024), an 8956% increase. Reported emissions went from 62 tCO₂e to 366 tCO₂e over the same span (up 495%).
What does a site EUI of 81.5 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. 5901 Optical Ct's 81.5 kBtu/ft² across 67,701 sq ft works out to about 5.5 billion Btu (1,617 MWh-equivalent) in 2024. Its source EUI of 228.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,616,912 kWh of electricity and 10 thousand gallons of water for the year.
Which law requires 5901 Optical Ct to report its energy use?
