The lighting environment is a factor that significantly affects the physical and psychological aspects of occupants of a building. In particular, educational facilities should be designed to provide adequate natural lighting because it has a profound impact on students&rsquo / health and learning performance. Although environmental certification sy...
Nowadays, discomfort glare indices are frequently calculated by using evalglare. Due to the lack of knowledge on the implications of the methods and parameters of evalglare, the default settings are often used. But wrong parameter settings can lead to inappropriate glare source detection and therefore to invalid glare indices calculations and erron...

Flashing yellow warning lights are important for worker and driver safety in work zones. Current standards for these lights do not address whether and how they should be coordinated to provide course-way information to drivers navigating through work zones. A field study in which the intensities and flash patterns of warning lights along a simulate...
A high luminance contrast between windows and surrounding surfaces can increase the risk of discomfort glare, which can diminish office workers' satisfaction and productivity. This research explores how increasing the luminance of areas surrounding the window using an innovative electric wall-washing system could improve subjective scores for the w...
The optical performances of plastic bag photo-bioreactors for microalgae production as shading systems for windows were assessed. The micro-algal growth rate and the light transmittance of prototypes were monitored in a photo-incubator and in a real room. Daylight in the room with algae and the energy demand for lighting EDl were then simulated usi...
Discomfort glare is common problem in modern buildings that employ highly-glazed façades. Glare not only has negative impacts on occupant comfort but can also increase energy use in buildings. Yet a robust discomfort glare metric, particularly with regards to daylight, has proven elusive. The Unified Glare Probability (UGP), developed using 493 sur...

Adaptive curve headlights swivel with steering input and are linked to reduced insurance claims and improved visual performance. This study assessed glare experienced from adaptive curve high-intensity discharge (HID), fixed (non-swiveling) HID and fixed halogen headlights - all tested in low beam mode. Twenty participants rated glare from vehicles...

The two physiological responses studied here to characterize discomfort glare under various lighting conditions had significant correlation with the subjective evaluation. The correlation between discomfort glare and physiological responses suggests an objective way to characterize and evaluate discomfort glare that may overcome the problems of con...
