Michael White Presents Evidence-Based Lighting at National AIA Convention

In coming years architects will be asked to provide innovative environments that support the changing demands of a more diverse work force using complex technology, as well as meet the needs of an aging population. The scope of design considerations is widening as evidence from scientific research explains how the (artificial) built environment affects mood, behavior, physiology, and health. The value proposition for architecture is therefore changing to include evidence-based design that addresses biology, in addition to classic values of aesthetics and function.

Within this context, light is emerging as a key element in architecture that delivers measurable benefits to the individual, the organization, and society. This session explores the use of daylight, architectural light, and darkness to mediate the affect of indoor living on a species adapted to live in the natural world. We will touch on natural history and present an overview of the current science in a straightforward and understandable way, and provide references to published journal articles.

The new non-visual pathway of photoreception will be explored along with the affect on circadian rhythms, physiology, and behavior. The recently coined phrase ​“circadian light” will be explained, along with its unique parameters. We will tie this foundation to human performance. Using an evidence-based approach we will link the evidence to the design process and provide specific application examples. Since cost is implicit in every discussion, we will then provide tools to quantify the benefits of managing light and darkness in the built environment.
