The Energy Positive Portable Classroom optimizes photovoltaic roof surface orientation, naturally shaded north-facing daylight glazing, and modulated natural ventilation. All of these forces are balanced with the additional criteria of manufacturing and transport efficiency, functionality for classroom use, low operating costs and ease of maintenance. The manufacturing and delivery process, and the materials and products employed are all selected for minimum environmental impact and for maximum contribution to a healthy indoor environment. Wherever possible, materials are chosen to conserve resources, minimize initial and lifecycle maintenance costs, and to promote educational awareness of the natural environment and its relationship to comfortable and healthy living. The design focuses on performance issues directly impacting the learning experience of its occupants and the environmental quality of its community—thermal comfort, natural daylighting, indoor air quality, energy and resource conservation and generation.
