Abstract

Summary

This paper proposes a structured framework for integrating non-image-forming light effects—such as circadian entrainment and alertness—into daylighting design for buildings. It defines light factors (luminous and temporal), threshold values, and architectural design parameters to help designers evaluate and optimize indoor spaces for biological and performance outcomes.
