The Bullitt Center is a six-story, 52,000 ft2 building designed to be both energy-neutral and carbon-neutral, and is currently the largest net-zero-energy and net-zero-water commercial building in the world. The Bullitt Foundation and its partners will use the project as an educational instrument to stimulate new and innovative sustainable building technologies and practices.
Some of the mechanical systems, including the mechanical and electrical rooms and recycling and water treatment systems, will be on display for educational tours.


The Bullitt Center is seeking Living Building Challenge (LBC) certification whose requirements for sustainability are at this time the most stringent in the world. LBC requires the project meet rigorous standards in different performance areas—or petals. The Bullitt Center project focused heavily on the Materials Petal. PSF alone submitted documentation on approximately 350 materials for review. All mechanical systems, including plumbing, piping and HVAC, were installed by PSF Mechanical and services included start-up, test & balance and commissioning.
