Abstract
A field study was conducted in an office building to assess the effectiveness of photoluminescent material to facilitate occupant evacuation. The office building's four identical stairwells were set with different conditions; one had full lighting, one had reduced lighting, another one had reduced lighting with photoluminescent wayguidance signs and one had photoluminescent wayguidance signs with no other lighting output. Non-informed occupants evacuated through the 4 stairwells. Speed of movement recorded using video cameras showed a similar speed of movement when considering the different density of the 4 stairwells.
