Nowadays, the renovation program is being implemented in the megapolises of Russia. Innovative high-rise buildings are built instead of morally and physically obsolete houses, where non-traditional renewable energy sources are used to the fullest extent, under the effect of which they are located. The possibility to use solar systems with variation of their design parameters is considered. It is established that solar systems have high technical potential. The share of heat load, that is provided by using solar energy, varies from 4 to 84% depending on the time of the year. Economic indicators restrain the use of such panels. The payback period is about 8 years at the current cost for thermal energy.

The spread and influence of harmful substances from gas filling stations (gas stations) on nearby buildings, taking into account the aerodynamics of wind flows, is not well investigated. Studying process of the spread of harmful substances in natural conditions causes certain difficulties. Being based on the results of theoretical and experimental studies obtained earlier, the authors performed a numerical modeling of the spread of pollutants emitted from gas stations. As well the authors analyzed influence of these pollutants on nearby buildings taking into account the flowing air flows. The results obtained from numerical modeling make it possible to assess the state of the environment at any point and at any distance from the gas station and allows us to predict the degree of influence of atmospheric air pollution on the environmental safety of residential buildings during the construction of gas stations. Using numerical simulation, it also seems possible to assess the effectiveness of the implementation of planned measures to reduce the negative impact of harmful substances from gas stations.

The concept of the blog as a means of mass communication is studied, the theoretical aspects of the functioning of the blogosphere in the modern information society are revealed, the structure, functions and features of the blogosphere in Ukraine are analyzed. It shows how the mass media works to ensure the exchange of socially important information between large groups of people within a certain social microenvironment - the blogosphere.
