| Abstract: |
| The continuous growth of the world population and the fact that people spend most of the day indoors have increased the demand for energy (lighting). Electricity consumption, especially lighting and its supply in buildings, has become an important issue addressed by many researchers and developers through various solutions. In recent years, as awareness of sustainable development grew due to economic and social conditions, daylighting was considered an effective solution to save energy, significantly reduce pressure on existing energy infrastructures, and mitigate environmental impacts. The use of daylight in buildings using various traditional and innovative solar technologies is more than just an alternative or complement to electric lighting, as it has many economic, environmental and health benefits. This study focuses on systems that have been commercialized or at least have produced a large-scale prototype. Several systems were examined in terms of their components, historical development, economic feasibility, and current market status. The strengths and weaknesses of current technologies and the prospects for development and research in each sector were also discussed. Despite the enormous diversity of technologies, none of them is able to address all of the associated challenges. However, the most practical systems are those that are best adapted to different environmental conditions. Based on the available information on the market share of each system, the TDGS system is the most commercially successful, cheapest, easiest to install, and most efficient daylighting technology. |
