The building will incorporate innovative design strategies for sustainability, water savings and energy efficiency such as:

  • Improved glazing U-Value and Solar heat gain coefficients
  • Higher efficiency central plant and air delivery systems
  • Optimized facade
  • Enhanced daylighting and Visual Comfort
  • Greywater water recycling systems
  • Reduce water consumption by more than 30%


WSP USA is providing MEP, fire protection, and high performance design by Built Ecology for the project, which will be the tallest mixed-use building west of the Mississippi River.

The project will be designed to comply with Title 24 and the San Francisco Green Building Ordinance and will pursue LEED Platinum certification.

181 Fremont is the first approved recipient of SFPUC’s Grant Assistance for Large Alternate Water Source Projects.  The program is providing a $250,000 grant back to the client for installing an on-site greywater treatment system that saves 1,000,000 gallons of potable water per year. The system collects greywater from commercial and residential fixtures and reuses the treated water for flushing and irrigation within the building.  Approval from both SFPUC and SFDPH was acquired after it was proved the design adhered with their stringent regulations and requirements. The installation of the equipment along with low-flow fixtures will result in a total water use reduction of approximately 50%.
