Daylight saving time: an American Academy of Sleep Medicine position statement

Journal of Clinical Sleep Medicine (JCSM), 2020
The last several years have seen intense debate about the issue of transitioning between standard and daylight saving time. In the United States, the annual advance to daylight saving time in spring, and fall back to standard time in autumn, is required ...

An Evaluation of Useful Daylight Illuminance in an Office Room with a Light Shelf and Translucent Ceiling at 51° N

Buildings, 2021
The present study investigates the issue of computer-aided daylight evaluation in an office room with a light shelf and dropped translucent ceiling. In this type of room, daylight is admitted from two sources: (i) a standard window in the wall and (ii ...

Thermal and spectral impact of building integrated Mirrored Light Pipe to human circadian rhythms and thermal environment

International Journal of Sustainable Energy, 2022
Light holds an important place in the way of life of humans. The first type of lighting which could be exploited was daylight. Tubular Daylight Guidance Systems (TDGS) transport and distribute this daylight inside a building.
