Evolving theories of change: Rethinking the effects of office lighting on occupants

摘要

This paper proposes an overall theory of change that relates lighting in offices to a holistic view of human responses that contribute to the well-being of office workers. The proposed theoretical model considers how variations in the four fundamental lighting attributes -intensity, spectrum, spatial distribution, and temporal pattern - and their effects on visual performance, visual environment, and non-image forming responses. The model addresses external factors that may mediate these effects on the desired lighting related outcomes, which in turn determine the final impact on occupants. The model builds on prior conceptual models of lighting effects and informs design and research planning for office lighting.
