What does a site EUI of 74.1 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. Mt. Pleasant Library's 74.1 kBtu/ft² across 25,572 sq ft works out to about 1.9 billion Btu (555 MWh-equivalent) in 2018. Its source EUI of 175.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 416,500 kWh of electricity and 4,745 therms of natural gas for the year.
Which law requires Mt. Pleasant Library to report its energy use?
