For reading and writing in classrooms therefore a lot of energy is consumed in educational spaces. Limitation of fossil fuels and environmental pollution are two subjects that demonstrate the importance and significance of the present study. Previous studies show that window size and configuration have a significant effect on daylight quality but numbers and the ways of expansion of windows in horizontal and vertical directions of the wall have not been investigated in classrooms in hot and arid regions of Kerman city. The objective of this paper is to evaluate the daylight indicators in different classrooms when different numbers of windows (from 1 window to 5 windows) are applied both horizontal and vertical expansion in each window area from (10%c WWR to 60% WWR). This research has been done through the simulation of different classrooms in Design Builder software under Kerman weather data. Validation of Design Builder has been evaluated through experimental measurement of two actual classrooms and comparing the simulation results and experimental data. The findings of this research demonstrated that using a greater number of windows in classrooms causes a decrease in the amount of daylight penetrating the classrooms.

The research aims to develop sustainable daylighting strategies for contemporary buildings by drawing inspiration from traditional vernacular housing solutions. In this study, the daylight factors of a contemporary residential space with a central courtyard which is located in Kerman, Iran is evaluated. After modeling the building in Design Builder software, the U-values of the external walls, roof, floor and windows based on the available materials in the market of Iran are calculated. The results of daylight simulations are presented in term of Average DF (%), Work plane Illuminanace (Lux) and Uniformity Ratio as well as annual Indicators of daylight such as sDA and UDI. Zone 3 in the ground floor which is a space under top lit atrium acts as a source of daylight. Although, Zone 5 in the ground floor has reasonable daylight factor, the uniformity ratio is not acceptable due to simultaneously existing the areas of little and high illuminance. Zone 7 in the first floor as a public sapce can provide large potential for daylight utilization with DF equal to 2.6% and average WPI with 826 Lux because there is a possibility to receive daylight from east direction with designing central courtyard in the first floor plan.
