Formation of microclimatic conditions in the territories of the Southern cities
Incoming article date: 17.04.2023The development of modern cities, caused by the need to improve the living environment, contributes to the creation of new buildings and structures. As a result, the density of typical urban development increases, mainly with rectangular buildings. Such buildings, with closed areas of courtyard spaces, create extreme microclimatic conditions and aggravate the air exchange of territories, thereby violating thermal and environmental comfort. This situation is especially acute in the southern cities. The article analyzes the influence of modern typical building on the microclimatic conditions of yard spaces. The factors influencing the formation of the heat and wind regime of urban areas have been identified. On the example of a building with a characteristic orientation for the conditions of Dushanbe, a graphical-analytical calculation of the duration of facade insolation was carried out. The role of insolation in the formation of convective flows of thermal origin is determined. On the basis of field studies, changes in the maximum speed of convective flows near the walls of the building were determined. The role of convective flows of thermal origin in the formation of the heat-wind regime of yard spaces is indicated.
