Window covering

Poor privacy is often caused when windows are located on the ground floor, or face nearby neighboring high-rise buildings.

Aesthetic qualities of window coverings should also be considered, such as how the color, material, and style match the rest of the interior space.

[3] The color, as well as aperture size, known as Openness Factor, or OF, are two variables of fabric shades that can change view clarity perception.

Darker fabric shades with larger openness factors generally achieve higher view clarity.

The height of the blind and the angle of the slat can be determined by daylighting demand and solar positions (azimuth, altitude).

When the sunlight is strong, fully closed window coverings can decrease the cooling load while maintaining occupants’ thermal comfort.

When the outdoor temperature is extremely low, fully closed drapes or curtains can reduce the heating load.

Indoor conditions, such as furniture configuration or occupant position, may also affect the shade or blind control.
