Abstract: Many cities face environmental problems, which are currently receiving a lot of attention. The layout of the city' micro-district corresponding to the regulations can provide the most favorable environmental conditions due to air exchange. The building of the city has been developing for centuries, microdistricts have a layout that was regulated by the law, valid at the times of their construction. The object of research is the processes of air exchange in city districts Ц on the example of Krasnoyarsk. The method of analysis of scientific sources and standards was used for the study, which allowed determining the chronology of changes in factors affecting air exchange and building blocks. The study includes the solution of the following tasks: analysis of the building regulations affecting air exchange in the neighborhood; to determine the principles of planning a residential neighborhood and establish their compliance with the standards on the example of the city of Krasnoyarsk; to consider the prerequisites for the implementation of an environmental aspect in building codes. For the sake of clarity of the data obtained on the problems of air exchange and the principles of development of microdistricts, the history of the planning structure of the development of Krasnoyarsk is investigated. As a result of the study, a general characteristic of the development of regulatory requirements for the development of microdistricts has been identified and presented. The relevance of the topic is determined by the presence of a problem with the accumulation of harmful substances in residential neighborhoods in Krasnoyarsk. In the current planning methods of development in some residential areas of Krasnoyarsk, this problem cannot be solved due to the increase in height and density of buildings while maintaining the same values of distances between buildings, since the regulatory requirements of insolation do not ensure effective ventilation of the district. According to the results of the study, it was concluded that not all previous standards included effective regulations to ensure the necessary air exchange, or they are completely absent. In these standards, factors affecting effective air exchange (height of buildings, distances between buildings and the angle of the buildings) were determined by other requirements, such as sanitary and fire safety standards, insolation requirements.
