FSi Consulting Engineers

Sustainable, energy-saving design: it's what we do every day.
We are committed to high performance building design that saves energy, water, and operating costs. Projects improving both performance and efficiency are really the core of our work. So it's only natural that we've jumped at opportunities to get on board early with rating systems that quantify performance.
120+ LEED Projects
Our strong background in energy modeling and high performance design earned us the role of mechanical engineer for the King County North Transfer Station. King County has long been a leader in sustainability, and the North Transfer Station was the first transfer station to achieve LEED Platinum certification, and just the third Platinum project in Washington State. We've gone on to participate in more than 120 LEED projects, providing design, energy modeling, commissioning, and even leading the certification process.
Net Zero & Living Buildings
Now many of our clients are going to the next level, asking us to design net zero buildings that generate as much energy as they use, or Living Buildings, which generate more energy and collect more water than they use, and produce no waste. We have one certified Living Building under our belt, and several more in the works targeting the International Living Future Institute's Living Building, Net Zero, or Petal certifications.
