Photosensor-based dimming systems measure daylight contribution and automatically adjust artificial lighting to maintain target illumination levels. This approach ensures visual comfort and prevents over-lighting during bright conditions.

Mid-Range
Approach Detail
Install photosensors in zones reflecting different daylight exposure. Set target illuminance levels for each zone (typically 200-300 lux for circulation, 100-150 for seating). Program gradual dimming responses to avoid noticeable changes. Consider facade orientation—east-facing areas need different responses than west-facing.
Key Fixtures
DALI-dimmable LED downlights and linear fixtures, integrated photosensors, building automation controllers
Designer Notes
Create renders at multiple times of day showing artificial lighting contribution changing. Illustrate how architectural shading affects daylight patterns. Include realistic sky conditions in exterior views.
Best For
Hotels with large glazed facades, atriums with skylights, sustainable/WELL-certified properties
