Abstract

Uniformity: (the ratio of minimum illuminance to average illuminance) is an important and ever present phenomenon in lighting schemes: determining the 'feel' of any lit place. Past and present practice indicate a disposition toward higher uniformities in artificial lighting schemes than equivalent natural ones. This is mainly due to practical restraints but also, to some extent, attributed to cultural determinants. Practical work undertaken in working interiors established a consistent pattern of uniformity divergence between natural and artificial lighting in the order of three to five. The rift between uniformities of artificial and natural lighting could be made narrower with a two-fold implication of energy conservation as well as effecting better 'creative use of darkness'.
