WA City Home to One of the World’s Most Streamlined, Energy-Efficient Fire Stations

               Fire Station 72 – Issaquah , Washington

The City of Issaquah is now home to one of the most operationally streamlined and energy-efficient fire stations in the world. The station is designed to become the highest-rated LEED Platinum
fire station in the US.

The new 11,400 SF station includes 6,900 SF of living and office space and has three bays to house two
fire trucks and two emergency response vehicles. The City’s goal was to build a model fire station which exceeded the expectations of Eastside Fire and Rescue and was capable of achieving net-zero energy use.

High performance building features include a super-insulated rain screen envelope with triple-pane windows, radiant floor heating and cooling, high-efficiency bedroom fan coil units, solar and ground-source heat exchange, energy recovery ventilation, living area and bay day lighting, occupancy and use-monitored electrical circuits, photovoltaic power array, rainwater harvesting for toilet flushing and vehicle wash, high efficiency plumbing fixtures, FSC certified lumber wood framing and environmentally beneficial materials selection.

OAC delivered facilitation of a sustainable design charrette, consulting on design strategies to achieve zero-net energy performance and LEED Platinum certification, project delivery and bidding strategies, cost analysis and estimate reviews, design development and constructability reviews, on-site construction management and building commissioning.


  • Ground Source Heat Pump to pre-warm water for heating hot water
  • A heating & cooling system that pumps warmed or chilled water through the station’s floors •
  • Solar hot water heater 
  • A tight thermal building envelope that prevents heat loss and provides for a healthier indoor environment
  • Solar panels that convert the sun’s energy into electricity. When the panels produce more power than the building uses, the excess power goes back to the electrical grid, resulting in a credit for the station’s power bill 
  • Highly efficient appliances, equipment and lighting – the station utilizes natural light through skylights and strategically-placed windows
  • Electric plugs and lights that shut off automatically if room is vacant • An 8,700-gallontank that collects rainwater from the station’s roof. The harvested water is then filtered and used to flush toilets, wash trucks and clean laundry. This system saves more than 55,000 gallons of water per year and provides nearly 96 percent of the station’s water needs
  • Green materials, including interior finishes that are simple, durable and locally sourced. The station is built with 95 percent Forest Stewardship Council (FSC) certified wood from responsibly managed forests. At least 20 percent of the materials are made from recycled content, and more than 90 percent of the construction waste was recycled
  • All materials and finishes are also extremely low in volatile organic compounds (VOCs)
  • The City of Issaquah’s first electric vehicle charging stations

With the help of TCA, the new station also meets the 2030 Challenge’s 2010 threshold to reduce greenhouse gas emissions by 60 percent.
