Influence of Architectural Lighting on Health

Research on the influence of light on health and behavior may be translated into guiding principles that inform changes in architectural and lighting solutions in built environments. Lighting solutions involve site planning, building orientation, architectural openings, shading and screening systems, as well as electrical lighting systems.

Here is what the study recommends:

• Easy access to daylight or electrical light of sufficient levels to stimulate the wake/sleep system should be provided where and when possible.

• The programming of spaces for those who must work in darkness or in unnatural circadian patterns should prioritize easy access to daylight. Building orientation and openings should be designed to bring in controlled daylight where possible.

Controlling illumination is paramount, regardless of whether the source is from the sun or from lamps. Furthermore, it is not appropriate to assume that more light is better.

• Light must be controlled for glare, discomfort, and temperature effects.

• Lighting for safety and egress is essential.

• Lighting for visual acuity must meet the requirements for task performance. However, individuals have differing needs for vision, and control of intensity, spectrum, and distance will provide for better lighting conditions.
