The angle and spacing of the clerestories is optimized for maximum solar exposure of the PV panels while facilitating indirect daylighting and natural ventilation. To optimize daylight levels, the windows are shaded from direct sun with exterior aluminum sunshades. Acoustical dampening is essential to interior experience, and children’s ability to learn and distinguish spoken language is especially affected by background sound levels and surface echo. Floor, wall and ceiling systems and all mechanical and electrical equipment are designed to limit sound generation and dampen sound reverberation. Surfaces, materials, views, light quality and colors throughout the space are selected not only for health, sustainability, functionality and hygienic ease of maintenance, but also to provide vibrancy, fun and creative inspiration. ENERGY EFFICIENCY and energy production has been a major focus of design and construction for this building, which is designed to revolutionize the energy efficiency of typically energy-hogging portable classrooms.
