Explanation of the system dynamics model for altering the balconies in order to improve the efficiency of the common residential plans of the cities of Guilan province based on the space syntax.

Today's common housing is not only built for shelter, but it is an effort to produce a life-oriented space. Now, with the transformation of housing into a capital good and its price value and the necessity of providing comfort to the residents, it requires special attention. Therefore, the concept of performance efficiency based on the mechanism of today's common buildings in order to strengthen the utilization of spaces has a very special role. On one hand, with the understanding that residence is a process during which a person has turned the "place of being" into a home, and considering the discussions of recent years regarding the relationship between man and nature in apartment housing, the importance of looking at the relationship between man and the natural environment through Some kind of intermediate spaces like a balcony are established and gain meaning. Therefore, this research seeks to investigate the arrangement of balconies to improve the functional efficiency of these spaces in order to increase the desired spatial quality. In this regard, by using the system dynamics method, the effective indicators have been examined and the data has been measured with depthmapx software (0.50) and finally, the main results have been obtained through logical reasoning. The investigated samples were randomly selected from the common residential buildings of the cities of Guilan province in the government and private Constructions. Based on the results obtained, in the rearrangement of the balconies by increasing their connection with more spaces and also by increasing the area of the balconies and changing its position from the surface of the facade to the inside of the building, more access and visibility have been given to the balconies and also The depth of the spaces compared to the balconies has been reduced and its performance efficiency has been improved
