Orca at Whitworth K-8 Science/Greenhouse Building
Seattle Public Schools
FSi was the mechanical engineer for the new Orca at Whitworth K-8 science classroom and greenhouse building. FSi designed the HVAC, piping, and plumbing for the new stand-alone building. The building takes advantage of natural light and ventilation, and is conditioned without the use of mechanical refrigeration. Energy efficient radiant heating warms people and objects, not the air. A 7,100-gallon underground cistern collects rainwater from the new building and existing school roofs for irrigation and a dual-flush toilet. Other sustainable features include reused broken concrete for garden pavers; sustainable building products such as Ecowheat and cork panels, and recycled plastic lumber; external shading, Energy Star appliances; and conversion of the building site from 100% impermeable paved surface to 100% permeable gardens and paths.
