Predicting Daylight Illuminance for 15 CIE Standard Skies Using a Simple Software Tool

open access: yesFrontiers in Sustainable Cities, 2022
Estimation of internal daylight availability is the key step in evaluating various daylighting schemes. Interior daylight is often expressed as daylight factor under the traditional International Commission on Illumination (CIE) overcast sky. Nonetheless,

Rethinking daylighting and compliance

open access: yesJournal of Sustainable Design and Applied Research in Innovative Engineering of the Built Environment, 2013
Daylight in buildings is the natural illumination experienced by the occupants of any man-made construction with openings to the outside. Our attempts to formulate some measure of daylight provision in buildings can be traced back over a century, and the

The mathematisation of daylighting: a history of British architects' use of the daylight factor [PDF]

open access: yesThe Journal of Architecture, 2017
British post-war planning guidance proposed that cities be rebuilt according to scientific principles. Mathematical tools were devised to determine built form; daylight levels within buildings were to be evaluated using a metric called the daylight factor.

Daylighting in classrooms - the daylight factor as a performance criterion

open access: yes, 2014
Recent research has shown that environmental conditions in classrooms, and namely daylighting conditions, can influence students health, well-being and performance. In the last years several studies, dealing with the effects of environmental conditions in classrooms in the learning process, have been published (Winterbottom, & Wilkins, 2009; Barret ...

Daylighting Evaluation of Perforated Screen Façade with Light Shelf in the Tropics

open access: yesDimensi: Journal of Architecture and Built Environment
The use of large glass facades in buildings without external shading devices leads to a high daylight level, uneven daylight distribution, and glare. A perforated screen facade (PSF) is one of the shading systems that can provide daylight and view and ...
