“…Prayer halls are also used for studying students and reading the Quran during the day. The internal environment of the prayer hall also required additional lighting through window openings in the end southern wall, from the side of the mihrab and oriented towards Mecca and carrying sacred light [25,26].…”

The work aims to analyze the influence of translucent fences on the light environment in the prayer hall and internal premises with the traditional volumetric-spatial solution of stone mosques of the late XVIII - early ХХ centuries in Kazan (Republic of Tatarstan, Russia). Based on the study of stone mosques in Kazan it was revealed that the main factor was the creation of a complete architectural image of the mosque following the temporary style and solution of the internal light environment through windows and stained-glass windows. Windows and stained-glass windows were scaled using architectural elements and decor for the holistic perception of the object. The significance of the obtained results for architecture is to present recommendations for the organic use of the studied techniques and methods of work on the objects of the architectural heritage in the restoration and design of modern mosques.

“…Light shelves are considered one of the most effective way to overcome energy consumption problems through artificial lighting within a building [10,16]. A light shelf is an efficient daylighting strategy and shading device that improves the inferiority of interior illuminance atmosphere through obstructive continuous daylighting, thus resolving glaring difficulties inside the building.…”

“…Advanced daylighting strategies like Light pipe systems, prismatic glazing, and Mirror system are implemented to minimize the energy depletion by enhancing the circulation of day light within the structure [13][14][15]. In present-day additional schemes for example perpendicular and flat louvers, projections, and light shelves are established [16].…”

Energy consumption of lighting can be reduced by using different daylight control strategies. The rise in environmental distresses requires the necessity of natural light control systems. Light shelf is considered as excellent lighting control scheme that provides great lighting production and inexpensive prospect via entering the daylight inside the space. The aims of this study shows that the daylight efficiency and visual productivity are affected by the design parameters of light shelf such as its angle, location and height. In this research, Autodesk Ecotect 2011 is used for the daylight simulation of summer solstice and winter solstice days under overcast sky conditions on a nominated theoretical study space of an institutional building. Daylight simulation is carried out to evaluate the illuminance requirement within the selected space and analysis is also executed on the model with selected categories of light shelves including different positions, heights and angles. The acquired data is then exported on Radiance software intended for complete day-light investigation. The results of this research shows that external light shelf at a height of 7' and an angle of 20˚ is the most appropriate choice in prevailing the glare and it also enhanced the illuminance level to11.5% in 21st June and 10.6% in 21st December as compared to without light shelves. Furthermore, the shaded range is decreased by the rise in the angle of Light shelf which has a tendency to increase the inside average lighting. Hence, significant consideration should be given to the height and position of light shelves, since it has a superior effect on light shelf performance.

“…According to El-Darwish and El-Gendy [11], daylight should not enter from the Qibla wall to prevent causing glare and visual discomfort for worshippers facing the Qibla direction. Nevertheless, in Al-Farsi Mosque, two windows are placed on the sides of Mihrab in the Qibla wall, but with the presence of wooden shading screens (Shish); thus, the daylight is filtered, providing indoor natural lighting with minimum glare.…”

Mosques are the most significant building in Muslim communities, where people perform their prayers and gather for social activities. The architecture and design of mosques have undergone significant changes over the centuries due to cultural, economic, and climatic factors. This raises a question regarding the design of the modern mosque. This paper analyses the physical characteristics of two Mosques located in Jeddah city, Saudi Arabia, built at different time periods: the historic Al-Shafi'i Mosque, and the contemporary Al-Farsi Mosque. The analysis focuses on investigating the different design techniques used to lighten the interior space, and how this can be related to the identity of the mosques. In addition, it explores how the orientation of mosques, determined by the Qibla direction, has impacted the indoor lighting quality. This study provides some critical observations demonstrating the importance of the use of light in the mosque's interior, and the essential impact this has on psychological, physiological and behavioural responses of the mosques' visitors, with a focus on both daylighting and artificial lighting.
