Editor's Corner How the Sun's Path Can Inform Design Sun shining into a building provides free heat and natural light. It can also create glare and, when the heat isnt needed, discomfort and added demand for cooling. Using sunlight when its needed and deflecting its power when its not are two of the most important tasks in building design. The sun rises in the east and sets in the west. Because the earth rotates on an axis that is tilted, however, the sun doesnt stay exactly in the east or west. In summer, it rises north of east, travels high across the southern sky, and sets north of west. In winter, it rises south of east, travels low across the southern sky, and sets south of west. How high it gets in the summer and how low in the winter depend on how far you are from the Equator. (If youre reading this in the Southern Hemisphere, north and south are reversed.)
