Key contribution

Due to its dynamic properties, SageGlass has the power to control the daylight entering a space, thereby improving occupants’ well-being in buildings and promoting green architecture.


To connect building occupants with the outdoors, reinforce circadian rhythms, and reduce the use of electrical lighting by introducing daylight into the space.

Detailed requirement

The first requirement consists in providing manual or automatic (with manual override) glare-control devices for all regularly-occupied spaces.

Three options are proposed to measure the daylight in the building which has to meet specific thresholds:

  1. By simulating, evaluate the spatial daylight autonomy and annual sunlight exposure (2 or 3 points);
  2. By simulating, evaluate the illuminance levels (1 or 2 points);
  3. Measure the illuminance level when the building is finished (2 or 3 points)

Our contribution

By tinting or clearing, SageGlass regulates the level of daylight entering a space as a function of the external light conditions and occupants’ needs. SageGlass thus offers the possibility of designing with more glass to meet the daylight autonomy targets for LEED certification, while ensuring that the space also meets the targets for minimizing over-lighting and glare control. Tinting the glass fully (to 3.5% VLT or less) will achieve occupant comfort in direct sunlight or when exposed to intense reflected light.

Only SageGlass provides the ability to create up to three tint zones within a single pane of glass, so occupants can let in exactly the right amount of light and block the sun only where it needs to be blocked.


Did you know?

Daylight is the source of life and essential to our well-being, development and health. A recent study by neuroscientists suggested that office workers with windows received 173% more white light exposure during work hours, and slept an average of 46 minutes longer per night.
