Light is an important element to ensure the comfort of how an area is to be used as it can not only increase task performance, it will also assist in meeting the level of aesthetics to a desired outcome.
Generally, window and door furnishings are considered as to how they control light entering from exterior sources (be it daylight or lighting), however, with the properties of particular materials, the way light, from internal sources, will reflect or be absorped can also be something to consider as this may clash with selected styles or finishes.
Where your window or doorway is located on your premises will obviously determine the level of light (direct or indirect). Being aware of the cardinal direction (north, east, south, west) faced, any obstacles (trees, buildings, etc) that will stop direct light, as well as any impediments to indirect light (tree foliage, eaves, etc), will provide valuable information as to how the furnishing you choose should perform to your requirements.
As a guideline and not taking into consideration obstacles and impediments:
- West facing means the afternoon sun and very bright light in summer.
- East facing means morning sun and less direct light in summer.
- North facing receives the brightest light in winter.
- South facing receives minimal direct light year round.
The light entering an area can also include the heat from the sun, which in itself presents different choices in the selection of materials and their properties, as during the cooler months, this can be a welcoming occurence. However, during the warmer months, this can lead to excessive heat, all-the-while still with the need for light.
