Abstract :

Background and Objective: Using natural light during the day is known as a suitable means to reduce artificial lighting in non-residential buildings. Traditional Iranian architecture is one of the symbols of sustainable architecture, which has responded to the optimization of energy consumption, both in terms of low initial price and low current and functional price of the building. Weather conditions and living environment are very important parameters in the design of buildings that are provided to create a suitable space for human comfort. In this research, the main goal is the effect of the depth of the porch, the dimensions of the openings and the effect of the photovoltaic cell on the amount of natural lighting in the classroom. Material and Methodology: At first, Climate Consultant software was used to check the annual radiation level of Rasht city. With the help of this software and using the weather data of the city of Rasht, the annual radiation diagram of this city is checked and then based on the building specifications including; Physical structure, users, as well as annual weather data hour by hour, the location of the building, taking into account all the conditions, especially the accuracy and validity of the results of the calculation algorithms, two software Builder Design and DIALux for simulating Construction was selected. Findings: According to the surveys, the maximum range of light required in the classrooms is between 2150-1614 lux, while the light received by the investigated building is more than the maximum range. Discussion and Conclusion: The outputs of the software show that the presence of a porch with a shallow depth can be very effective in creating a filter to prevent the entry of high intensity of light and creating glare in the space. If the current classrooms require a significant amount of artificial light source. Also, the analysis shows that in the first floor, due to the use of photovoltaic cells, we see more lighting.
