Nowadays, there is an in-depth debate about the suitability of daylight saving time. The shift
of one hour during summer time allows a better use of daylighting reducing energy …

The proper design of courtyards and atriums is key in providing sufficient daylight inside
buildings as well as major energy savings in electric lighting. Although a suitable design …

Daylight dynamic metrics provide an alternative approach for the assessment of the energy
savings promoted by lighting control systems. This research aims to quantify the energy …

Daylight metrics act as a useful tool to quantify the potential of natural light in an architectural
space as well as the energy savings promoted by a suitable design of windows, atriums, and …

Featured Application This study proposes a new daylight dynamic metric which serves to
quantify more accurately the energy consumption of electric lighting for spaces with …

Abstract In Egypt and the Middle East, there is an obvious tendency of establishing new
shopping malls and indoor commercial centers that provide collective facilities. However …

Daylight dynamic metrics are useful tools for quantifying the switch-on time or the dimming of
electric lighting according to the architectural scenario. A variant of these metrics can also be …

The main aim of this article is to determine a suitable shape for lightscoop skylights, whose
main characteristic is a vertical opening oriented in the opposite direction to the solar …

This study examines the system performances of daylight dimming controls under various
photosensor conditions in an office space with three lightshelf configurations to propose …

Lighting systems account for a significant proportion of energy consumption in buildings.
Therefore, energy conservation within these systems can greatly enhance overall building …
