Carriage Hill Bethesda's 54.4 kBtu/ft² across 39,696 sq ft works out to about 2.2 billion Btu (633 MWh-equivalent) in 2024. Its source EUI of 152.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 632,891 kWh of electricity and 0 therms of natural gas for the year.
