Annotation: In article comparative analysis of methods of calculation of thermal and humidity envelope of porous concrete for graphic-analytical method provided in DSTU-N B.2.6 B-192:2013 has been given. Guidelines for design evaluation of thermal and humidity walling and existing methods provided in the SP 50.13330.2012 «Thermal protection deposited». The main requirement of the existing methods is that the resistance water vapor envelope should be more than two sizes: standard resistance water vapor with conditions unacceptable accumulation of moisture in the building envelope for the annual period of operation and the required resistance water vapor with conditions limiting moisture in the building envelope for the period of negative average monthly temperature of the outside air. The main requirement of graphic-analytical method of increasing the moisture content of the material in the thickness of the layer structure, which may be condensation from the cold period of the year must be less acceptable for insulation characteristics increase the humidity of the material. Based on the analysis, the main advantages and disadvantages of national and international methodologies.
Keywords: heat humidity condition, moisture, condensation.
