GSA Updates Standards Pushing Zero-Emissions Goal

The mandatory design and construction standards set performance criteria for 300,000 federal buildings nationwide.   September 24, 2024

As facilities in the private sector continue their efforts to operate more sustainably, adopt more energy efficient technologies and curtail emissions, the U.S. General Services Administration (GSA) — the landlord for federal facilities — also is doing its part. 

The GSA recently released updated sustainability standards for federal buildings. P100 Facilities Standards for the Public Buildings Service establish mandatory design and construction standards and performance criteria for 300,000 federal buildings nationwide. The updated standards aim to help the federal government reach its goal of net-zero emissions from all federal buildings by 2045. 

P100 requires that facilities adopt advanced energy conservation strategies and eliminate on-site fossil fuel use. The standard calls for grid-interactive efficient buildings, leverages innovative technologies through GSA’s Green Proving Ground, requires the use of low-embodied carbon materials, and directs potable water reuse. The 2024 P100 establishes exceptional benchmarks for: 

  • Electrification. New standards for building equipment and systems to be powered by clean energy sources 
  • Embodied carbon. Requirement to use low-embodied carbon materials, including salvaged, reused, regenerative and biomimetic options 
  • Energy efficiency. Enhanced building envelope performance to minimize energy loss and improve overall efficiency 
  • Grid-interactive efficient buildings. New measures to support a more resilient, responsive grid 
  • Water reuse. Mandating that buildings have a 15 percent potable water reuse rate 
  • Construction decarbonization. New low-carbon methods for constructing federal buildings, including clean energy operations, material salvage and offsite assemblage.
