“…Skylight is a special fenestration element that delivers a uniform level of illumination over an interior space. However, its performance varies under different sky conditions and solar intensities (McHug et al, 2004;Al-Obaidi and Rahman, 2016b). Al-Obaidi et al (2014a) conducted a conceptual study to evaluate the behavior of solar radiation in the form of light and heat that fell upon, interacted with, and was emitted from an SL system in a single-story building.…”

“…Electrical lighting began to be supplied to most users on a large scale in 1950; that changed the appearance of indoor lighting [81]. When we discuss the relationship between buildings and daylight, we first consider the structure and equipment located outside and on the façade of the building; and the system that can transport daylight from the outside of the building into the indoor area is called the daylighting system.…”

Daylighting systems make daylight illuminance possible, and the development of prototype daylighting systems can provide more efficient daylight illuminance. The purpose of this article is to review the development and performance of prototype daylighting systems in the last decade. The passive and active daylighting systems are listed separately and divided into the four categories by the presence and absence of hybrid. Each prototype daylighting system was evaluated in terms of cost and daylight performance and as well as their novel optical design. We evaluated the architecture and daylighting principles of each system by reviewing individual prototype daylighting systems. The cost of prototype systems still poses a challenge to development. How to use passive or active systems in different environments and whether or not electrical lighting assistance is needed is a controversial issue. However, active daylighting systems equipped with solar tracking systems are still mainstream. This research is a valuable resource for daylight researchers and newcomers. It is helpful to understand the advantages of various prototype daylighting systems and commercial daylighting systems that have been developed for many years; moreover, it is also possible to know the research directions suggested by the prototype daylighting systems. These will be of further use in developing innovative and better daylighting systems and designs.

“…The greater the depth of a room, the poorer it is illuminated by daylight [18]. Al-Obaidi and Rahman [63] critically investigate optimum design requirements of top-lighting system, which conclude that system type, sky condition and human comfort are significant factors. Designs with top-lighting must be examined carefully as potential overheating resulting from inappropriate top-lighting design should also be avoided [22,64].…”

Daylighting design has become prevalent in modern buildings in the effort to create a more sustainable living environment. Past and recent bodies of research emerged are mainly focused on the different methods of predicting and measuring daylight level and various range of daylighting technologies available. Despite a wide range of developed and commercially available daylighting systems have been reported, their applications have been limited by a lack of studies on their utilisations and high initial costs. Computer simulations have been frequently used in the past to investigate daylighting performance due to reliable and accurate predictions. However, additional simulation time and variable level of skills and knowledge required are major drawback of computer simulations. This paper includes and pools information on all major daylighting design topic in the built environment. The study critically reviews and compares daylighting design principles, strengths and weaknesses of different range of daylighting systems and calculation methods, such as, scale model with artificial sky, full scale model for field measurement, numerical modelling and manual calculation procedures with the aid of diagrams or tables. Such information could be of useful for engineers, researchers and designers to assess the suitability of applying these systems and technologies in different building types and examine the potential of energy and cost savings.
