One of the most important systems for ensuring the required air quality in Orthodox churches is the ventilation system. Mechanical ventilation is getting contaminated during operation. The air, passing through the air ducts, contains dust particles, including pathogenic bacteria. To prevent bacteria from multiplying in the ventilation system, bactericidal filters must be used. Halls of Orthodox churches belong to public buildings with a large crowd of people with a long stay. Such premises require a bactericidal efficiency of at least 90%. For the ventilation systems of the church of St. Theophan the Recluse, the authors proposed and implemented a device for bactericidal air treatment using ultraviolet radiation. The bactericidal effectiveness of this device was 92%, which is higher than required. The authors recommend using the proposed device for public buildings.

Reconstruction of buildings inevitably entails improving the thermal protection of premises, however, the development of measures for the thermal insulation of the existing building structures is impossible without evaluation of thermal characteristics of these structures, primarily the resistence to heat transfer. Evaluation of the materials according to their characteristics reference is often not possible. The main causes is the lack of information about construction materials to the inner layers of the long-erected buildings. Arise a number of difficulties in conducting field surveys due to the practical absence of the stationary conditions. Heat flux on the surface can change simultaneously with changes in temperature, as walling have thermal inertia, and need some time to change the temperature distribution in the structure thickness. To determine the actual heat transfer resistance of enclosing structures must take into account the dynamics of change of temperature and heat flow on the surface of the enclosure. When determining the actual heat transfer resistance needs to consider the time distribution of heat waves through the walling.

To describe the dynamics of the temperature field in the surface layers of the earth taken up the heat balance of the earth's surface. Taken into account are three components of the heat flow: convective heat transfer with air, solar radiation, heat flow from the surface layers of the soil. The boundary conditions on the surface of the soil is considered the temperature of the ground surface, which is determined from the heat balance of the surface layer of the sun radiation. The temperature distribution in the soil is determined using the method of finite differences. A layer of soil has a certain thermal inertia, which leads to delaying the achievement of minimum temperatures in the soil column relative to the time of achievement of the minimum surface temperature. In the surface layer of soil to a depth of approximately 300 mm, is almost complete attenuation of the diurnal temperature fluctuations in the month of June with account of solar radiation in conditions of the South of Russia.
