Award Criteria

  1. Architectural Excellence
    Silverdale Elementary in the Central Kitsap School District lacked the space to accommodate the community’s growing student enrollment. Facing more than two years to design and construct an addition using traditional methods, district leaders explored options to more quickly provide students with a high-quality, healthy learning environment. Their solution: a 7,500-square-foot SAGE (Smart Academic Green Environment) school from Pacific Mobile Structures. The collaboration resulted in the largest, most complex SAGE project ever undertaken, with five classrooms, a flex area, restrooms, and storage/utility space with two main entries on the side and end of the building. Connected by a bright and airy 17-foot corridor, the building also features 28 clerestory windows, series of trusses and an exterior that matches the school’s existing architecture. An innovative steel floor structure and cork walls offer noise-abatement qualities, providing a quiet learning environment for students.
  2. Technical Innovation & Sustainability
    The Silverdale Elementary SAGE school is the first of its kind, representing an evolution from SAGE classrooms to larger, more complex SAGE school buildings. The SAGE school delivers all the health and environmental benefits of affordable green construction techniques and non-toxic building materials. Features include upgraded HVAC systems with energy recovery ventilation for healthier air, noise reduction and energy conservation, twice the amount of window square footage compared to standard relocatable classrooms, natural ventilation from operable windows and low-velocity fans, efficient mechanical and lighting system designs, and a unique 17-foot, light-filled corridor created from roof and floor modules. The SAGE school exceeded the stringent criteria of the Washington Sustainable Schools Protocol (WSSP) for materials and waste, energy and water usage, indoor environmental quality and other factors.
  3. Cost Effectiveness
    Design and construction of the SAGE school cost approximately 15 percent less than traditional methods yet provide a 50-60-year life span comparable to stick-built structures. The building exceeded the Washington Energy Code by approximately 30%, with a white TPO roof refracting the sun to regulate interior temperatures for increased comfort and reduced energy costs. BioPCM, a phase-change material in the walls, reduces HVAC power consumption by 35 percent while maximizing energy savings. Having built and installed more than 100 SAGE classrooms since 2013, Pacific Mobile Structures and Blazer Industries have continually improved quality and efficiencies. Pacific Mobile Structures led the project as a collaborative partnership with the school district, factory Blazer Industries, and Portland State University architects.
