Ceilings with high light-reflectance create brighter spaces.
A well designed ceiling with high light reflectance improves the overall illumination and lighting uniformity of the room, directly affecting working comfort, well being and productivity.
Ceilings with high light reflectance, returning up to 90% of light back into the space, can reduce energy consumption by up to 20%.
Ceiling systems are a key element of energy conservation. A well designed ceiling with high light reflectance improves space illumination, allowing for fewer light fixtures, a reduced electrical light output, lower maintenance costs and a reduced cooling load.
Daylight and electrical lighting represent the two primary sources of lighting in the workplace. The light reflectance of the ceiling, floor and wall surfaces play the second most important role for overall illumination of the room, directly affecting working comfort and productivity.
Benefits of High-LR Ceilings:
- Light Reflectance ≥ 90% ⇒ 20% cost saving with indirect lighting
- Total building energy savings up to 11%
- 7% savings in cooling system energy
- High light reflectance ceilings contribute to LEED®, BREEAM, HQE, DGNB and Ska credits by improving visual comfort
