Shading devices shield windows and other glazed areas from direct sunlight in order to reduce glare and excess solar heat gain in warm weather.
Their effectiveness depends on their form and orientation relative to solar altitude and azimuth for the time of the day and season of the year. Illustrated below, are six basic types of solar shading devices. Their form, orientation, materials, and construction may vary to suit specific situations. Their visual qualities of pattern, texture, and rhythm, and the shadows they cast should be considered when designing the facades of a building.
These six quick thumbs represent the different types of devices. Use this sketch language when working on conceptual stage.
