daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. window configuration significantly affects the intensity and uniformity of daylight. this paper aims to investigate the effect of wind...

Daylight is a dynamic source of illumination in architectural space, creating diverse and ephemeral configurations of light and shadow within the built environment. It can generate contrasting levels of brightness between distinct geometries or it can highlight smooth gradients of texture and color within the visual field. Although there are a growing number of studies that seek to define the r...

EvalDRC is a newly developed daylight analysis tool for the evaluation of Daylight Redirecting Components (DRC) in architectural spaces. It focuses on the accurate simulation of light redirection with help of the lighting software environment RADIANCE. It employs various key technologies, among them are: a) the daylight coefficient method, b) characterisation of the light redirection behaviour ...

This work reviews the effect of parametric programming on visual performance, daylighting and shading in office buildings in Tehran-Iran and studies their influences that help not only to reduce the glare but also to promote useful daylight illuminance through promoting visual comfort. It starts by establishing a review of the effective parameters on visual comfort indices, glare indices, and d...

As people increasingly work in indoor environments, the need to provide natural lighting is becoming more widely recognized. Recent modelling standards such as LM-83 require the use of climate-based metrics based on daylight coefficients, rather than illuminance-based metrics that simulate single points in time. While calculations based on daylight coefficients are fast, computation of the dayl...

Daylight in buildings is both aesthetically pleasing and a sustainable means of offsetting costs for space conditioning and electric lighting. However, poor use of daylight can cause glare that impedes worker productivity. Traditional means of predicting lighting levels for indoor spaces through simulation are timeconsuming, which inhibits exploration of daylighting potential in new buildings. ...
