Performance Information

Daylight Penetration

The LightLouver Daylighting System outperforms conventional side-daylighting strategies in all performance categories: daylighting contribution, solar control, visual comfort, energy savings and installed cost. LightLouver units extend the daylit zone deep into the building, and completely eliminate glare and direct sunlight penetration onto work surfaces from the daylight window. Energy savings are nearly double that of a conventional light shelf, at one third the installed cost. Below, the LightLouver Daylighting System is compared to a traditional light shelf daylighting solution and a conventional fenestration design.
