How has Alpha Gamma Delta's energy performance changed over time?
BuildingCensus holds 3 Ann Arbor disclosures for Alpha Gamma Delta, covering report years 2021–2023. Site EUI moved from 53.5 kBtu/ft² (2021) to 54.7 kBtu/ft² (2023), an 2% increase. Reported emissions went from 92 tCO₂e to 104 tCO₂e over the same span (up 13%).
What does a site EUI of 54.7 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. Alpha Gamma Delta's 54.7 kBtu/ft² across 24,000 sq ft works out to about 1.3 billion Btu (385 MWh-equivalent) in 2023. Its source EUI of 80.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 564 thousand gallons of water for the year.
Which law requires Alpha Gamma Delta to report its energy use?
