Sun-shading Devices

Shading a building from the sun reduces glare and reduces overheating, thereby creating a more comfortable space while reducing cooling loads. Some types of shading devices can selectively allow the sun to shine into a space during the winter to also reduce heating loads. Operable elements further enhance the functionality and efficiencies offered by these types of devices.

Component-Specific Considerations

  • Entrances, porches, and balconies that provide shading and weather protection.

  • Projecting eaves and other elements that shield building faces and windows from harsh summer sunshine while permitting lower angled, winter sunlight to reach the building when feasible.

  • Sun-shading devices such as horizontal projections screens, and others on curtain walls and at windows.

  • Large overhangs on orientations exposed to intense sunlight and weather to protect walls and shield openings.

  • Awnings, horizontal projections, and screens that can respond to sun exposure, glare, and solar gains and that can mitigate extremes. These are especially useful where they are adjustable to accommodate seasonal or sun-movement differences.
