A Review of Daylighting System: For Prototype Systems Performance and Development

Abstract

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.

Thermal building upgrade with off-grid PV system: a Polish case

“…For the highest possible utilisation of the energy potential of PV panels, it is suggested to optimise their tilt angle, or additionally to commission a tracking system (Ngo et al 2020;Whang et al 2019); the 18-year average optimal angle of the position of photovoltaic panels for Poland amounts to approx. 36 o , with 32 o for Malta and even 45 o for Finland (see Fig.…”

Otomasi Penerangan Pada Solar Tubed Room Yang Dioptimasi Dengan Light Tracker

“…Penerangan ruangan menjadi salah satu tren yang memanfaatkan cahaya matahari karena kemampuannya mengurangi biaya penggunaan maupun ketahanan lampu konvensional (bertenaga listrik) khuusnya pada penggunaan di industri. Wang et al, (2019) melakukan review terkait pengembangan dan performa beberapa prototipe sistem penerangan ruangan dari sistem single solar lighting yang hanya menggunakan cahaya matahari saja hingga hybrid lighting yang mengombinasikan cahaya matahari dan lampu konvensional.…”

The Energy, Economic and Environmental Efficiency of a PV Installation Cooperating with a Heat Pumpin the Central Part of Europe. Case study

“…Graph 5 in turn presents average ITH values recorded by the Photovoltaic Geographical Information System (PVGIS) for European Communities in the years 2001 -2019, which indicate that Poland is rated twentieth in terms of the conditions of insolation, and the ITH in here is lower by 16% and 43% than European average and the maximum average for Malta, respectively, and higher by 17% than the minimum average recorded for Finland. For the highest possible utilisation of the energy potential of PV panels, it is suggested to optimise their tilt angle, or additionally to commission a tracking installation [30,31]; the 18-year average optimal angle of the position of photovoltaic panels for Poland amounts to approx. 36 o , with 32 o for Malta and even 45 o for Finland (see Figure 6).…”
