Access Roads, Car Park and Building Perimeter

Operations will often run late into the night making the lighting essential for employee safety and building security. Mounting positions are not as limited as within the service yard so architectural lighting can be selected to enhance the look of the building.

Spill light and upward light should still be minimised.

For recommended lux levels please see CIBSE : SLL Lighting Guide 1 - The Industrial Environment (2012, updated 2018)
