What does a site EUI of 71.8 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. Sierra Alloys Company's 71.8 kBtu/ft² across 73,000 sq ft works out to about 5.2 billion Btu (1,536 MWh-equivalent) in 2023. The disclosure also reports 1,531,194 kWh of electricity for the year.
