Siting: Building Orientation
A building's orientation with relation to the sun will impact the school's ability to optimize passive heating and cooling, natural ventilation, and daylighting.
Generally, it is best to elongate the building along the east-west axis, thus increasing the area of the building that faces north or south. By doing this, the building's exposure to the sun will be maximized. By optimizing exposure to the north and south directions, schools have access to a more diffuse light that is suitable for daylighting. Light comes from the east and west only when the sun is low in the sky, therefore using windows for lighting on those sides is likely to cause glare.
Collaborative for High Performance Schools (CHPS)
(Best Practices Manual Volume 2, Site Planning Section, Guideline SP1: Optimum Building Orientation) CHPS aims to facilitate the design of high performance schools in California - environments that are not only resource efficient, but also healthy, comfortable, well lit and contain the amenities needed for a quality education. CHPS has developed a set of Best Practices Manuals (available at www.CHPS.net) to create a new generation of high performance school facilities in California.
