Harborview Medical Center in Seattle is working with design firm McKinstry on installing a nearly 100-KW solar array on the roof of its West Hospital building. Once completed, the array will be the largest solar array for any hospital in Washington State, according to an announcement from McKinstry.

The project costs $925,000 and entails installing 6,600 square feet of solar panels on the roof, the Puget Sound Business Journal’s Coral Garnick reported. Harborview is also replacing its roof at the same time to add insulation, reducing the building’s heating and cooling requirements.

A $50,000 grant from the Seattle City Light’s Green Up program and a $47,000 grant from the Department of Commerce’s Energy Efficiency Grant Program are helping to fund the project, according to McKinstry.

The hospital, which is owned by King County and managed by the University of Washington, has been working with McKinstry for more than eight years on reducing energy costs and increasing the reliability of the medical center’s infrastructure, according to the design firm.

Previous projects included lighting upgrades, fan replacements, and heating and cooling upgrades, McKinstry said in an announcement about the solar array. “Cumulatively, these projects are saving Harborview over $500,000 annually and reducing the medical center’s carbon footprint by 155,394 pounds of CO2,” the design firm noted.

Washington-based solar installation company A&R Solar signed on to install the array on the hospital building’s rooftop. Installation is slated to be completed this month.
