Posted by: Rebecca Whitham, Communications Last Thursday, Woodland Park Zoo was recognized by the Seattle Design Commission with a design excellence award for our new Humboldt penguin exhibit! The award is in recognition of Seattle’s best capital improvement projects. Other honorees were Fremont Peak Park, Thornton Creek, Seattle Center Century 21 Master Plan, and Sound Transit Central Link. Visitors may be fixated on the nose-to-beak views of the penguins in the exhibit, but it’s the harder to see sustainable elements of the exhibit that captured the Design Commission’s attention. With support from Seattle City Light and Seattle Public Utilities , we installed an energy efficient ground-based geothermal heat pump that uses the Earth’s below-ground temperature to keep the exhibit’s water at a penguin-friendly 55 degrees year round, as well as an innovative water filtration system. These features will save nearly 22,000 kilowatt-hours of energy and 3 million gallons of water per year.
