Analysis of effective factors on integrated local management in peripheral rural settlements of Tehran metropolitan
Abstract
Among the most important factors affecting the efficiency of users of educational spaces, especially students, is the quality of light because the intensity and excessive amount of light in the space leads to impaired visual comfort in students and this leads to problems such as lack of concentration, distraction, headache and other physiological disorders. In the present study, the visual comfort and light performance of a sample of three rural classes in hot and semi - humid climate were evaluated. The purpose of this research is evaluation of daylight indices (DLA) and (UDI) and dazzled state (DGP) indexes in school sample classes and comparing the performance of daylight and glare criteria proposed with orientation and window-to-wall ratio (WWR) in order to provide the required light, while providing solutions to improve daylight performance in this space. If the evaluation is given according to the schedule of the students ' attendance at the classroom and the minimum of the luxury required by the standards, it is considered as the standard 300 luxury. Visual comfort conditions are evaluated for four different locations of students with respect to window in sitting position in all three classes. Now, after defining the daylight and glare indicators, these indicators have been analyzed using Rhino7 software and Grasshopper, Ladybug (Ver 0.0.68) and Honeybee (Ver 0.0.65) plugins. According to the evaluations done, the north - east class, which the window - to - wall ratio is %20.49, has a better visual comfort and daylight performance than the other methods for improving the performance of daylight received in this class. according to the proposed solutions, the values related to the DLA and UDIuseful indices are %65.48 and %6.22 respectively compared to the current situation studied for the north - east class, despite the visual comfort conditions. therefore, if the required light is not provided in the space, by changing the reflection of the inner surfaces up to about %6.30, by changing the light transmission coefficient from glass up to 56 / 56 percent and by increasing the ratio of openings to the wall surface up to about %11.56 , it can add up to about %47.62 improvement in daylight performance in the interior .
