What does a site EUI of 17.0 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. Wilder Regent's 17.0 kBtu/ft² across 48,400 sq ft works out to about 0.8 billion Btu (241 MWh-equivalent) in 2025. The disclosure also reports 241,553 kWh of electricity and 2,247 thousand gallons of water for the year.

Which law requires Wilder Regent to report its energy use?
