How has 125 Sixth Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 125 Sixth Street, covering report years 2015–2024. Site EUI moved from 134.5 kBtu/ft² (2015) to 138.8 kBtu/ft² (2024), an 3% increase. Reported emissions went from 1,092 tCO₂e to 1,028 tCO₂e over the same span (down 6%).
What does a site EUI of 138.8 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. 125 Sixth Street's 138.8 kBtu/ft² across 162,547 sq ft works out to about 22.6 billion Btu (6,612 MWh-equivalent) in 2024. Its source EUI of 283.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,679,775 kWh of electricity, 69,266 therms of natural gas and 2,173 thousand gallons of water for the year.
Which law requires 125 Sixth Street to report its energy use?
