Concepts In Passive Design #2 Devices For East And West Shading
A major source of heat in buildings is direct solar radiation through east and west windows--welcome heat energy in cold weather, but a summertime problem. Since Florida has such a long cooling season and generally a short heating season, it is especially important to protect east and west walls, windows, and sliding glass doors from the summer sun while allowing adequate light to enter the building year-round. From a lighting standpoint, natural daylight is on the whole quite good but it can produce unwanted heat and visual glare if not properly controlled.
