The Effect of Using Smart Dynamic Skins on Increasing Visual Comfort and Use of Daylight in Schools

Creating suitable lighting conditions in educational environments is one of the most important factors in the design of such spaces. if daylight is used to provide it, it will have significant effects on the mental and physical conditions of students, as well as reducing energy consumption. but for the design of space lighting, attention should be paid to not creating too much or too little light and glare in the space. one of the modern solutions to provide these conditions is the use of dynamic and smart skins that react based on the amount of light received from the sun and its position in the sky. in this research, with the help of computer analysis and by keeping all the conditions constant, the impact of the presence of dynamic smart shade and its absence on the amount of sufficient light supply and the possibility of glare in a classroom is examined. these analyses were done at 12 pm on the 21st of march, june, september and december in a classroom located in the southern part of an educational building in tehran, which has a hot and dry climate. the purpose of this research is to prove the better performance of the designed dynamic and smart facade, in providing proper light and no glare in the climate. based on the obtained results, it was found that the design with the help of iranian-islamic architectural patterns in smart shade systems, especially on the southern side of the buildings, leads to the creation of visual comfort in the environment. furthermor, according to the results obtained from the comparison of the two facade systems, in all the analyses, the intelligent facade, unlike the case without the shade, has been able to provide enough light for more than 50% of the class area at all times, without causing glare. this result shows the good performance of dynamic smart shade in providing daylight.
