The First Net-Zero Elementary School in the Puget Sound

Founded in 1986, Puesta del Sol is a pre-K–5 Spanish immersion choice elementary school enabling students to become proficient in Spanish and English while thriving academically and socially as members of a caring and safe learning environment.

To better accommodate all students from a more centralized location, the District is demolishing the existing elementary school and constructing this new, 96,500-SF three-story campus to house up to 650 students with a net-zero goal. The new campus includes a synthetic playfield, covered play area, outdoor learning areas, garden, landscaping, and 110 parking stalls.

We provided electrical engineering services for this new school featuring a 368-kW solar photovoltaic capacity with 125-kW battery storage system, a significant contributor toward the school’s goal of net-zero operations. The electrical distribution system was designed for the facility to operate in island mode, which allows the building to be disconnected from the utility grid.
