Circulation Spaces

The design and usage of circulation spaces and corridors varies widely, but they need to be illuminated for safety and ease of use. Signs and notice-boards should be well-lit so they are clearly visible and easy to read. Good vertical illumination allows faces to be recognised easily.

Illumination Levels

SmartScan Lighting Management

Significant energy savings can be achieved in areas with good levels of daylight by using daylight dimming. Presence detectors can also ensure circulation spaces are not left illuminated when not being used.
