Daylight as a light source with a spectrum dependent on solar position and sky conditions, it is also rich in the short-wavelength portion of the visible spectrum. This is proven to support both alertness and circadian sleep. It’s subsequently serves an effective purpose in office buildings and other places of employment.
In addition to encouraging productivity at the work place, the daily variation of daylight, night light and dark cycles are proven to support human health. This is reflected in light manufacturers mimicking the natural light perception with electric light sources and lighting systems. But there is truly no substitute for the effects of natural sunlight. It can, however, be enhanced to influence the mood in a room with such components of stained glass windows.
Elements of design such as colored glass to placement installation- such as skylights and actual size- are critical points to consider for realizing the potential benefits. Spaces implementing natural light sources hold the potential to yield such benefits as energy savings and improvements to human health and productivity.
But the positive impact from natural light is only true when sunlight direction is harnessed correctly. For example, it would make no sense to have sun shining in a workspace only during non-work hours or having a stained glass color which encourages a mood counter to the desired cause and effect. If “in wildness is the preservation of the world,” then integrating architecture with nature and implementing components of the outdoors is very important.
