Abstract

The paper describes aspects related to the design stages of modern residential buildings. Reflected is the lack of requirements for the presence or absence of stagnant zones in residential premises of apartment buildings. Convective flows were simulated in the living room of a multi-room apartment of a multi-unit standard panel house. It is shown that the presence of stagnant zones along the inner surface of the enclosing structure reduces the energy efficiency of the building.

Introduction

Today, they try to make multi-apartment multi-story building projects as individualized as possible, using modern technologies, architectural techniques, and planning decisions. The rejection of the mass use of standard series, which allowed to duplicate standard designs of multi-story buildings, tying them by the nature of the construction site and the peculiarities of the existing architecture, has a positive effect on the appearance of modern housing estates and built-up areas. Nevertheless, taking into account the economic realities of today, standard projects are widely used to provide the population with so-called economy-class housing, especially when building residential complexes, but much more attention is paid to ensuring the individual appearance of individual buildings and harmonious coordination of buildings of the same type into the original architectural ensemble. If earlier, by the appearance of the apartment building, it was possible to predict how the apartments are located on the site, how many rooms are in each of them and what planning solutions are used, today it is quite difficult to do this. In this regard, the question arises of preparing a comprehensively justified design of the house, taking into account modern requirements, including and energy-saving requirements.

Conclusion

As a result of the work carried out, the presence of a stagnant zone (a zone without airflow around it) was determined for a small part of the internal surface of a structural element of a living room adjacent to the B-10 assembly (Fig. 1, 4) over the entire height of the room and a width of 30 cm (counting from the corner) . The presence of this zone leads to a local increase in air humidity in the above-described location of the second construction corner bedroom 23 of the block section of the 83 series. Taking into account the detected lower limit values of the temperature of the above angle, mold will form in it, with an increase in the humidity of the structure, heat losses will increase. In connection with the foregoing, we can conclude that it is necessary to simulate convective flows at the design stage of an apartment building, which will allow you to correctly locate utilities, in particular, heating appliances. This approach will improve the quality of life of future residents and increase energy efficiency at home without additional capital investments
