Health and human performance largely determined by the conditions of climate and air quality in residential, administrative and residential and public buildings. At that, in turn, is influenced by the external environment and the climate, and the geometric dimensions of the room, and thermal performance building envelopes, and the location of the premises (Orientation), and many other factors. The result is the formation of complex systems, which control decision-making in conditions of multifactor. In hygienic purposes it is necessary to strive to create the best indoor microclimate conditions, regardless of changes in the factors that affect the climate in residential, administrative and residential and public buildings. Develop systems to ensure the necessary microclimate parameters - it is a complex and important task, which will depend entirely comfortable and cozy environment for the person. The problem of the present time, there is a steady increase in the energy consumption of these systems, due to the rise in price of non-renewable energy sources, and our job is, to simulate the work of software systems necessary microclimate for the changes in the factors that affect it and to minimize the use of non-renewable energy sources [4,5]. Analysis of recent research and publications. Domestic and foreign hygienists to establish a connection between the climate in the room and in the workplace and the state of human health [1,2,6,7]. Formation of the indoor climate of residential, administrative and residential and public buildings is influenced by many factors that have already noted earlier. Study of the processes of influence of various factors on human health is of great complexity. If we consider each process separately, and in this case they are not currently amenable to theoretical description clearer. To simulate the effect of these factors studies were conducted, which showed that, with sufficient accuracy manage experimentally investigate the electrical field in the liquid conducting medium as an analog of the thermal field [8]. Isolation of previously solved problems. Known methods for modeling are approximate and have drawbacks that reduce the accuracy and limited scope. Therefore, one way to obtain effective thermal solutions is a simulation of thermal processes with further analysis of the results. It was suggested that the thermal field in the room to simulate electric field in the plating bath, and the analog heat flux between surfaces of any room space assumed current density between the surfaces of the model. The smaller the distance between the selected measurement points, the more accurate will be recreated actual picture patterns in the electric field and hence the thermal field in the room. But this method does not enable to take into account all the possible variations that affect the formation of indoor climate.
