The destructive effects of many human activities, such as construction and the emergence of critical conditions such as excessive greenhouse gas emissions and consequent global warming, have pro‎mp‎ted everyone to take action. In developed countries, about 40% of the energy consumption is related to the construction sector, a significant part of which is spent on lighting. Therefore, today, the importance of proper design to use the maximum natural light in spaces to save energy has been increasingly considered. The form of the building and especially its facade, has a significant effect on the amount of daylight received. Different parameters in different phases of design make the building form. In this study, among these parameters, the effect of indentation and protrusion of facade parts on the amount of daylight received by indoor spaces is investigated because it seems that protrusions and depressions on the outer surface of the form and facade due to shadow The launches, circulation and rotation of the air in dealing with them, as well as changes in the amount of solar energy received, have a special effect on the amount of daylight received by the building. The purpose of this study is to obtain all suitable cases in terms of depression and protrusion of facade parts and small quantities and optimal dimensions of these items in order to receive best daylight so that future architects can use these data in the concept stage and phase zero to architectural details and execute more precise design decisions based on specific numbers. The research method is a quantitative method based on computer simulation using HoneyBee software in which first by considering a modular structure, all the different shapes for the formation of concavity and convexity were defined and after simulating daylight for all these modes in Honeybee software, the optimal modes were obtained. Which were selected by a large difference from other modes in the amount of natural light were superior. To measure the amount of daylight received, the sDA index, which is one of the most important methods of numerical measurement of daylight and is also used in the global lead standard, was used. As a result of comparing and interpreting the simulation data, it can be said that the highest daylight reception is related to the time when we have convexity (protrusion) in all parts of the facade, and then the concavity (depression) of the facade alone increases the daylight reception. In the case of the combination of protrusions and recesses of the façade parts, it was concluded that the higher the ratio of the recesses to the protruding parts, the better daylight reception.
