Analysis reveals 17% reduction in electricity use and CO2 emissions in buildings using smart daylighting systems.

Daylight-aware control strategy resulted in a 17% reduction in electricity consumption, particularly in sunny months.
The life cycle assessment showed a corresponding ~17% decrease in use-phase CO2 emissions based on regional grid factors.
Impact assessments were conducted using an attributional life cycle framework consistent with ISO 14040/14044 standards.
The operational payback period for embodied impacts was approximately 18–20 months, highlighting economic viability.

Sertaç Görgülü (2025) studied this question.
