Summary

This study proposes an age-adjusted weighting curve for Equivalent Melanopic Lux (EML) and a computational simulation method to evaluate circadian lighting performance in office spaces, accounting for users between 25 and 55 years old. Results are benchmarked against WELL Certification circadian lighting criteria, highlighting that standard daylight autonomy metrics alone are insufficient and that age must be factored into lighting design for health and wellbeing.

Key Findings

A weighting curve for EML was derived based on 98.5% melatonin suppression thresholds, calibrated for different age groups between 25 and 55 years old.
Computational simulations of office spaces using Daylight Autonomy (DA) metrics and local climate files revealed that age-adjusted melanopic lux requirements differ meaningfully across the studied age range.
Existing WELL Certification circadian lighting benchmarks were found to provide a useful but incomplete framework when age-related differences in melanopic sensitivity are considered.
The study concludes that current human-factor metrics and simulation tools remain insufficient for fully assessing circadian health effects in architectural design.
