Natural Light Management
Effective natural light management improves the visual comfort, well-being, and productivity of a building’s occupants while reducing the need for artificial lights. This provides visual comfort indoors while enabling occupants to see the outside.
VISUAL COMFORT
Indoor visibility is a key factor for the occupants’ sense of comfort. In order to maintain an optimal visual environment, automated solar shading systems take many parameters into account in order to provide occupants with natural light entrance while maintaining a view to the outside, optimal levels of luminosity according to the building’s activities, a good contrast level, and elimination of glare.
RESULTS
A more comfortable workspace
With automated solar shading devices, building occupants benefit from more natural light without the associated disadvantages. The ideal levels of contrast and brightness are maintained at all times and excessive glare is eliminated.
Energy savings on artificial light
Lighting accounts for a significant portion of a building’s total electricity consumption and energy costs (36% on average based on USEIA study). With automated solar shading devices, this cost can be reduced significantly, yet users are able to retain their individual preferences.
