LightLouver Benefits and Features

Lighting is the largest end-use consumption of electricity in commercial buildings. Approximately 887 billion kWh of electricity are consumed in commercial buildings each year.

The innovative LightLouver™ system uses passive side-lighting optics to daylight the space. Daylighting reduces energy consumption while enhancing the quality of the visual environment. LightLouver™ can be as easily applied as conventional interior mini-blinds for both new and retrofit construction. LightLouver™ is being refined and developed for widespread commercialization where, in addition to the significant energy savings benefits, there will be personal (productivity and health) benefits, and environmental (pollution reduction) benefits.

Passive optics, no moving parts, no seasonal adjustments.
Redirects daylight 14 horizontal feet for each foot of LightLouver™ unit height.
Provides uniform ambient illuminance levels in the daylit space.
Reduces or eliminates ambient electric light energy use when combined with daylight controls.
Eliminates direct sunlight penetration and glare above a 5° altitude angle.
Integrates easily with all fenestration systems and requires less space than light shelves.
Less expensive than exterior or interior light shelves, and provides superior daylight performance.
