The noise state in buildings is a general process of sound energy distribution in the building volume. The sound energy emerging in separate rooms falls on enveloping structures of the rooms and penetrates to the adjacent volumes. In this case the enveloping structures of the noisy rooms become the sources of noise for other rooms. In public buildings flat rooms widely occur, in which the noise from technical rooms often penetrate. The authors observe the principles of evaluating indoor noise in a flat, which penetrates from adjacent premises through the walls. The method of calculating sound pressure levels in rooms is offered. The method takes into account the patterns of direct sound distribution from the flat noise source (wall) and the conditions of the reflected sound field creation in flat space of finite and infinite length. The direct sound energy distribution character is determined by geometric parameters of the wall shedding the noise. The method provides the desired calculation precision of the sound pressure levels.

Due to wide implementation of enveloping structures with increased heat-insulation properties in modern construction here appeared a necessity to assess their moisture conditions. Assessment of moisture conditions of enveloping structures is carried out according to maximum allowable moisture state basing on determining the surface of maximum damping. In relation to it the necessity of additional vapour barrier is checked using moisture balance equation. Though the change of indoor climate parameters in premises is not taken into account in moisture balance equations defined for different seasons. The author improves the method of calculating moisture protective parameters of enclosing structures according to the maximum allowable damping state for a year and a period of moisture accumulation. It is shown in this article that accounting of temperature and relative humidity change of inside air allows specifying calculated parameters of indoor climate in residential and office rooms in assessment of moisture protective properties of enclosing structures for the case of an effective enclosing structure with a façade heat-insulation composite system. Coordinates of the maximum moistened surface of the envelope depends on indoor climate design parameters. It is concluded that the increase of requirements for moisture protection of enclosing structures when using design values of temperature and relative humidity of internal air according to the Russian regulation (SP 50.13330.2012) is not always reasonable. Accounting of changes of indoor climate parameters allows more precise assessment of moisture protective properties of enclosing structures during their design.

Setting standards of thermal resistance of building envelopes is a current task related with energy saving and energy efficiency of building envelopes. The problem of choosing the factor determining the standard thermal resistance also stays current even after updating of the Construction Norms. The author consider the concept of norming the thermal resistance of building envelope, in which the temperature of the inner surface of a building envelope providing comfortable temperature conditions in premises. The main task of an architect, who is designing an energy efficient building envelope is providing comfortable conditions in premises both in cold and warm periods of the year. The temperature of the inner surface of building envelopes should be included into the construction norms as the main criterion providing comfortable air temperature in premises.

Subject of research: the main heat loss occurs through the building fence. In the paper, the object of research is enclosing structures with different thermal conductivity. The problem of moisture accumulation in the wall is quite relevant. One of the main problems in construction is saving on building materials and improper design of building envelope. This in turn leads to a violation of the heat and humidity regime in the wall. This paper presents one of the methods to address this issue. Purpose: description of heat and humidity conditions in the wall fence of high-rise buildings. It is also necessary to analyze the relationship between the thermophysical characteristics. Materials and methods: the temperature distribution in the layers will be analyzed on the basis of the structure consisting of 10 layers; the layer thickness is 0.05 m. Materials with different thermal conductivity were used. Each subsequent layer differed in thermal conductivity from the previous one by 0.01. Next, these layers are mixed. The calculation of the humidity regime includes finding the temperature distribution along the thickness of the fence at a given temperature of the outside air. The quality factor of the temperature distribution is the maximum average temperature. This research are conducted in the field of energy efficiency. Results: the higher the average wall temperature, the lower the air temperature differs from the wall temperature. In addition, the higher the average temperature of the wall, the drier the surface inside the wall. However, moisture accumulates on the surface inside the room. The working capacity of multilayer enclosing structures is determined by the temperature distribution and distribution of moisture in the layers. Conclusions: moisture movement through the fence is due to the difference in the partial pressure of water vapor contained in the indoor and outdoor air. A layer with minimal thermal conductivity should be located on the outer surface of the wall in a multi-storey building. The maximum change in the amplitude of temperature fluctuations is observed in the layer adjacent to the surface by periodic thermal effects. It is also taken into account that the process of heat absorption has a great influence on the temperature change in the thickness of the wall fence to the greatest extent within the layer of sharp fluctuations (outer layer). The Central part of the wall (bearing layer) will be the driest. These calculations are satisfied with the design of the ventilated facade.
