Title Comparison of the energy effectiveness of office lighting systems.
Bibliographic information Sep. 1976, Vol.6, No.9, p.30-36. Illus. 9 ref.
Abstract This paper suggests a method for rating the effectiveness of general office lighting systems by considering 2 aspects of lighting. The first is the quality of environmental lighting, the luminous relationships seen in horizontal viewing; it can be rated in terms of the visual comfort probability (VCP). The second is the quality and quantity of visual task lighting; it can be rated in terms of equivalent sphere illumination (ESI). The possibility of using the average and minimum values for VCP and ESI as figures of merit for comparing the effectiveness of different lighting systems is examined. 19 general direct lighting systems were investigated. The influence of luminaire spacing and of luminaire light distribution is studied. Results are discussed in terms of discomfort glare.
