Daylight & View

Daylighting is the practice of using windows, skylights and other forms of fenestration to bring light into the interiors of buildings, using various mechanical means to control the amount of daylight, and employing complementary electric lighting systems (including controls). Daylighting is perhaps the most demanding and challenging form of illumination, because of its variability and even more so, because of its impact on many aspects of a building. In traditional modern building design, various disciplines tend to work independently: architects design the mass and fenestration, structural engineers design the structure, mechanical engineers design HVAC and electrical engineers or lighting designers design the lighting. Who among this group is designing the daylighting system? It is evident that to design daylighting properly, integration of design and coordination among disciplines is essential.

There are, however, some basic observations that can help lighting designers, architects and engineers begin to understand the potential impact of lighting, and they are discussed in this section. By thinking about daylighting as part of the lighting system, these decision makers can encourage the use of daylight in basic building types where the benefits can be realized with relative ease.

Benefits of Daylight as a Source
Recent studies have provided scientific evidence and self reported data that people respond positively to daylight: they feel better, they work better, they learn better.

Daylight in Lighting Terms
Daylighting in architecture tends to be employed by architects in pursuit of the aesthetics and human factors of daylight.

Daylighting Control
Most buildings have some windows and other potential forms of daylighting. For example, classrooms can easily be designed to provide adequate daylight throughout most of the year.
