Dynamic & Diffuse Light
leverages varying intensities of
light and shadow that change
over time to create conditions
that occur in nature

A space with a good Dynamic & Diffuse Light condition conveys expressions of time and movement to evoke feelings of drama and intrigue, buffered with a sense of calm.


Lighting design has long been used to set the mood for a space, and different lighting conditions elicit differing psychological responses. The impact of daylight on performance, mood and well-being has been studied for many years, in a variety of environments, and as a complex field of science and design, light has been extensively studied and written about.


The objective of the Dynamic & Diffuse Light pattern is twofold:
to provide users with lighting options that stimulate the eye and
hold attention in a manner that engenders a positive psychological or physiological response, and to help maintain circadian system functioning.
The goal should not be to create uniform distribution of light through a (boring) space, nor should there be extreme differences (i.e., glare discomfort)
When the lighting difference between adjoining sources or surfaces has a brightness or luminance ratio of greater than forty-to-one, glare may occur,which diminishes visual comfort (Clanton, 2014). For work areas, luminance ratios between task and immediate surround should not exceed 10 to one. So while dramatic lighting differences may be great for some religious, socialization and circulation spaces, they are not a good idea on work surfaces.

Diffuse lighting on vertical and ceiling surfaces provides a calm backdrop to the visual scene. Accent lighting and other layering of light sources creates interest and depth, while task or personalized lighting provides localized flexibility in intensity and direction. These layers help create a pleasing visual environment (Clanton, 2014). movement of light and shadows along a surface can attract our attention. For example, the dappled light under the canopy of an aspen tree, or the reflections of rippling water on a wall. These patterns tend to be fractals, and the brain is attuned to moving fractals

Design considerations for establishing a balance between dynamic and diffused lighting conditions:

  • Dynamic lighting conditions can help transition between indoor and outdoor spaces.
  • Drastically dynamic lighting conditions, such as with sustained movement, changing colors, direct sunlight penetration and high contrasts, may not be appropriate for spaces where directed attention activities are performed.
  • Circadian lighting will be especially important in spaces the people occupy for extended periods of time.

Naturally occurring
• Daylight from multiple angles
• Direct sunlight • Seasonal light
• Firelight
• Moonlight and star light

Simulated or Constructed
• Multiple low glare electric light sources
• Illuminance
• Light distribution
• Ambient diffuse lighting on walls and ceiling
• Day light preserving window treatments
• Task and personal lighting
• Accent lighting
• Personal user dimming controls
• Circadian color reference
• Color tuning lighting that produces white light during the day, and minimizes blue light at night
