When the subject of buildings and daylighting arises, most people's thoughts will turn first to windows. To the uninitiated, it seems a simple formula: more windows, more daylight; fewer windows, less daylight. But designers know that effective use of daylighting in a building design involves more than just letting in light to otherwise darkened spaces. Too much daylight, especially the glare of direct sunlight, can be as undesirable as too little daylight. Daylighting also affects how much heat enters a facility; the benefits of natural light quickly can be outweighed when the heat that comes with it creates a space uncomfortable to occupants. When the building in question is a school or university, the importance of effective daylighting strategies becomes even more critical. A classroom with good daylighting design can help students boost their academic performance, studies have shown. So for designers of education facilities, decisions about windows go beyond the question of quantity. By determining how these decisions affect the lighting in learning spaces and the energy costs of heating and cooling the building, schools and universities can construct energy-efficient education facilities illuminated with ample daylight.
