Concern for the environment and with energy use will lead to the increasing use of wood-frame construction in elementary schools. Buildings which employ this technique stand up well to earthquakes and also effectively resist heat. In conjunction with wood-framed buildings, a new energy saving system incorporating the most up-to-date environmental control technology must be developed. Lighting accounts for most of the energy used in schools: Electric lights are used to make up for the uneven illumination found in many classrooms. To understand the current state of the light environment in the classroom of ordinary reinforced concrete building, upper desk surface illumination was measured in three classrooms: a room with south-facing windows, a room with north-facing windows, and a room with both south-facing and north-facing windows. In addition, a wood-frame model with a light duct between the floor trusses was built and the light duct's effect was examined. As for reduction of light energy and for evenness of lighting, rooms with north-facing windows were the most energy efficient and are therefore preferable. The above results suggest that school buildings should be planned in such a way that they avoid direct light from south-facing windows, and that rooms with north-facing windows should be increased. The author will collect further thermal and environmental data and continue to build more detailed models to study the lighting of elementary school buildings.
