Annotation: The contemporary theories of physical processes that determine thermo and technical characteristics of the air gap in the buildings with ventilated facade systems have been analyzed. The results of field observations have been given. The minimum thickness of 15 mm air gap on the example of ventilated facade system «Marmorok». Have been considered Research was conducted in term modernized five story building at the 1st, 3rd and 5th floors with luminal starting profile of 0, 30 and 100 %. On the basis of experimental studies and theoretical calculation the air speed, air temperature and humidity in the air gap in the design conditions have been determined. The dependences of the air speed in the layer on the outside temperature have been done. The changes in humidity in the layer depending on the degree of openness of the starting profile have been found, and also it has been found out that the nature of temperature change of the gap at subzero temperatures of the outdoor air.
Keywords: ventilated air layer, temperature, humidity, air speed, thermomodernization.
