Summary
This paper addresses a gap in current daylight metrics by developing methods to evaluate both temporal and spatial light exposure profiles for typical building occupants, moving beyond simple grid-based illuminance data. The practical implication is that lighting designers can better assess whether a building's daylight design will adequately support occupant circadian health across different times of day and building locations.
Key Findings
- Current grid-based daylight metrics are insufficient for evaluating circadian-relevant light exposure, as they do not capture temporal variation or occupant-specific spatial experience.
- The study proposes occupant-centric temporal and spatial light exposure profiles as a more comprehensive evaluation framework for building-scale daylight assessment.
Categories
Sleep & Circadian Health: Evaluates how building occupants' actual light exposure profiles affect circadian health outcomes.
The Science of Light: Develops methods to assess melanopic and circadian-relevant light exposure using spatial and temporal data from building environments.
