The non-visual effects of light have become a hot topic in the study of how lighting
environments affect humans. For an extended time, living and working in an isolated …

Buildings are designed to respond to functional and regulatory needs, providing comfortable
conditions to occupants, offering satisfactory environmental settings, minimising health risks …

Dynamic lighting is a potentially promising solution to meet the individual's chronobiologic
and psychological needs at specific times of day or for specific activities. Yet, few studies …

Light dosimetry aims to measure personal light exposure with wearable sensors, which is a
complex multistep procedure. The resulting data may be used to investigate non-visual …

Indoor environmental quality is closely-related to the occupants' comfort, performance and
health. However, very few studies on indoor environmental quality were done in university …

Melanopsin-based quantities (circadian stimulus and melanopic illuminance) depend on the
spectral irradiance at the eye level, in turn resulting from the light sources' spectral power …

The relationship between daytime light, especially morning light and sleep, has not been
well documented. People who work in an office spend most of their time indoors and thus …

A comparative analysis is presented of a smart window with grating filter and a conventional
smart window fully covered with switchable layer using the same chromogenic material in its …

Beyond vision, light influences human circadian rhythms and buildings' energy
consumption. Design solutions are needed to satisfy visual and circadian requirements …

Cognitive performance is essential to foster learning. High CO2 concentrations are common
in classrooms and can lead to reduced cognitive performance. Negative air ions (NAIs) can …
