Innovative Heating & Cooling System for Healthcare Center

May 4, 2017

Coffman mechanical engineering principal, Don Iverson, was quoted in an article in the Whidbey News-Times about a unique heating and cooling system being installed at the WhidbeyHealth Medical Center. The new $50 million hospital addition is installing a variable refrigerant flow (VRF) system that can adjust quickly to patient and staff needs in particular areas saving up to 50 percent on energy costs.

This climate-based system is zone controlled and far more efficient than traditional "reheating" systems that warm the cold air for areas that don't need cooling. Traditional systems can add up to 40 percent of all the energy consumed by a hospital. Although the system is unique, it is not a high cost design to get this energy efficiency.

When the construction is completed this summer, the VRF system should save the hospital a significant amount on their energy bills and will also provide patients with cleaner air that is recirculated in their rooms and not the entire building. The reduction in the center's energy could also qualify the hospital for a maximum rebate from Puget Sound Energy.
