“…The cost is based on the system cost mentioned by these solar researchers in the article. Evaluations for the three designs of the system: concentrators, transmission components and diffusers [5,32,[39][40][41][47][48][49]52,99,110]. The daylight performance standard is whether the daylight factor is above 2.5% or whether it can effectively supply more than 500 lx/m 2 of illumination.…”

“…In order to attain more effective use of dynamic daylight, stable optical components and active devices of the daylighting system were studied. Common optical components are high-reflectivity light pipes [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], Fresnel lens [32][33][34][35][36][37][38][39][40][41][42][43][44], linear Fresnel lens [45][46][47], optical fiber with different materials [32], light guide [39], parabolic concentrator [48][49][50], Compound Parabolic Concentrator (CPC) [38,47,51,52], dish concentrator [1,53], cold mirror [48], IR filer [32,38], hot mirror [49] and prism structure ...…”

“…After concentration or compression, the sunlight is transmitted through the optical fiber, light pipe or free space [105]. The technology transmitted through the optical fiber is also called Fiber Daylighting System [32,[38][39][40][41][42][43][44][47][48][49][50]52,[101][102][103][104][106][107][108].

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.
