BACKGROUND Daylight availability data are essential for designing effectively day lighted buildings. In respect to no available daylight availability data in Iran, illuminance data on the south facing vertical surfaces were estimated using a proper method. METHODS An illuminance measuring set was designed for measuring vertical illuminances for standard times over 15 days at one hour interval...

This paper presents a methodology for optimizing skylight design with the considerations of thermal comfort, daylight availability and energy performance by integrated daylight and thermal simulation. Dynamic thermal modelling programmed IES and daylight simulation engine Radiance are used as simulation tools to study energy performance of a shopping mall atrium with a skylight on the roof ...

The differences included in the new version of the standard prEN15193-1 to calculate the LENI were analyzed, especially focusing on the approach to calculate the daylight supply factor (FD,S). The estimation of the daylight availability does not only rely on the calculation of the daylight factor but it also accounts for the climate, the orientation of openings, and the presence of mobile sun s...

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...

Climate-Based Daylight Modelling (CBDM) is a methodology that allows the prediction of several measures of daylight using the sky condition from location specific meteorological data. CBDM was originally used as a means for predicting indoor daylight availability and intensity. Since the scalability of the method has been proved it has been applied at different architectural scales for differen...

Smart window designs have emerged as a means of providing dynamic regulation solar energy and daylight, enhancing indoor comfort, achieving building conservation. We evaluated novel design that integrated thermotropic (TT) material Transparent Insulation Material (TIM) present the investigation in this paper. The Parallel Slat TIM (PS-TIM) structure contained within unit provides extra thermal ...

The use of daylight in educational settings has a significant impact on the well-being, attention, and academic achievement students. However, providing adequate daylighting without glare can be difficult, especially deep-plan layout classrooms, because is not constant its strength varies with distance from façade, necessitating additional solutions frequently. In this study, tubular guidance s...
