This review article describes the most significant works of recent years on the humidity conditions of building envelopes. Three main aspects of the problem are considered. The first of them - this is the effect of electromagnetic radiation on human life and health. Are the most effective means of protecting human from electromagnetic radiation of a modern building. The physical effect of the passage of the electromagnetic signal through the walling confirmed experimentally. Practical recommendations for the weakening of the electromagnetic signal. The paper reveals the relationship between the power of the electromagnetic signal, entering the house and humidity building envelope. The second problem - the water vapor permeability of building materials. We studied the latest developments in the field of water vapor permeability of materials walling. A comparative analysis of modern methods of testing water vapor permeability of building materials used in the official regulations, the latest tests on the new domestic equipment. These advantages determine the water vapor permeability when exposed to the wind flow on the sample in comparison with the classical methods of determining the vapor permeability. A qualitative assessment of new installations and methods for the determination of the water vapor resistance. The questions of determination of water vapor permeability of building materials. Explore new approaches to determine the water vapor permeability of composite systems facade insulation with outer layers of plaster. This paper analyzes the domestic and foreign techniques for the calculation of operational humidity of the building and operating of thermal conductivity. It is concluded that the technique of field inspections of buildings is the most accurate of all, but not very cost competitive. Defining operational sorption isotherms humidity tests positive only for single layer construction structures and can not be applied to the determination of the production of multi-layer moisture. The method of linear dependence of the thermal conductivity of the material from moisture. As an example of the opposite method of the linear dependence of the thermal conductivity of the moisture is given a nonlinear technique additives for heat insulation of expanded polystyrene. A closer look at a modern method of calculating operational humidity of building materials, depending on the "quality of heating rate." The method of the European Union on the definition of operational humidity. Comparison of the data for the calculation of the results of the EU method with Russian modern techniques. As described in the most promising method of mathematical modeling to determine the operational humidity by means of numerical calculations. Arguments are presented the advantages of this method compared to the other six. It is indicated that current new developments in the field of moisture conditions of building structures in other countries, too, are based on mathematical modeling of processes of heat transfer and moisture transfer. The shown are the basic principles of calculation for each of the methods. Noting their strengths and weaknesses. Suggested further ways of development for research humidity conditions. Also shown on the need to integrate communication and humidity conditions to protect a person from electromagnetic radiation.
