The Significance of Environmental Factors in Human-Centred Lighting Policy

Abstract

Lighting policies and the influence of light colour parameters on humans and the environment are complex. The opinions of experts and the optimisation of night-time lighting policies create a suitable nightscape that satisfies users’ needs and minimises environmental impacts. This study aims to provide a nightscape design policy for outdoor spaces considering environmental factors. This evaluation can provide multidisciplinary policy recommendations and evaluate the position of environmental considerations in human-centred lighting design. Initially, the factors affecting the night landscape are identified and priorities are subsequently determined on a smaller scale based on the typology of Tehran’s nightscape. The data output from these prioritisations is used to develop how the lights in the night landscape can be improved for various spatial typologies. Finally, a human and environment-friendly conceptual model is developed.
