Summary
This paper reviews how internal shading devices and architectural features influence daylight provision and melanopic illuminance in indoor spaces, highlighting the gap between building design and circadian health outcomes. It underscores the need for standardized methods to evaluate circadian-effective lighting in architectural design, as people spend the majority of their time indoors and their light dose is largely determined by building characteristics.
Key Findings
- Key circadian lighting parameters identified include spectrum, light levels, spatial pattern, and temporal pattern (duration, timing, and prior exposure history).
- Review concludes that despite existing research, no shared standardized method exists for evaluating the effects of architectural lighting on circadian rhythm regulation.
- Indoor light dose is heavily dependent on building-specific factors: location, orientation, window dimensions, external obstructions, room geometry, and surface optical properties.
Categories
Sleep & Circadian Health: Reviews how architectural factors (building orientation, window dimensions, shading) affect light dose and consequently melatonin secretion and circadian rhythms.
The Science of Light: Examines melanopic illuminance and its relationship to spectral, spatial, and temporal light characteristics in indoor environments.
