The paper provides a brief analysis of the history of urban development, depending on the consideration of natural and climatic conditions, in particular, the movement of air masses. The construction practice is taken into account when accounting wind conditions, which primarily involves the effective placement of industrial enterprises, sanitary break zones, residential development and public space. Theoretical studies of the aerodynamic properties of two models of buildings of simple shape, based on some experimental data, are presented. Comparing the flow directions calculated theoretically with the directions measured experimentally by different authors, it is confirmed that the proposed theoretical methods well reflect the actual picture of the flow around a rectangular profile by an air flow. For the considered models No. 1 and No. 2, according to the test results, it was determined that the pressure on the windward planes (walls) of different heights depends on the ratio between the thickness of the boundary layer and the height of the building, respectively, buildings of small height are almost entirely located in the boundary layer, i.e. in the layer of air, which, touching the surface of the earth, is slowed down due to the roughness of the underlying surface, as the speed of air movement decreases as it approaches the surface of the earth, and on the surface it is zero.

This article discusses the method for removing the harmful substances and excess heat from the stationary candle holders in niches. The method is designed to remove the excess heat and dust during the candles’ burning and stationary candlesticks near the icons and paintings in the niches of monasteries and temples. It is carried out by removing the heated contaminated air through the slotted gratings, which enters the ventilation ducts, from where it is thrown out through the valve outside.

This paper contains the climatic construction conditions analysis in the Volgograd region and considers the standard architectural forms of buildings and structures.

The paper deals with the pre-project analysis questions in the construction of heating systems in Orthodox churches, the basic requirements for heating systems in the temples, a brief comparative analysis of the options for the construction of heating systems. We propose estimates for the construction of heating systems using economic criteria and comfort criteria that are the basis for the final solutions.
