ABSTRACT
Reduction of dependence on expensive imported energy resources causes the need to use energy-saving technologies at construction of the new and renovation of existing buildings. Thermal insulation of facades and the use of sealed windows are widely used to reduce the load on the heating system now. However, the lack of supply of fresh air through leaks in the outer fence negatively affects the hygiene indicators of indoor air. Design of supply-exhaust ventilation is a must for maintaining regulatory of air quantity and improving air quality in rooms of passive houses. Reduce of the load of the ventilation system allows the use of thermo ground-air heat exchangers. This article describes the possibility of using geothermal ventilation in the passive house by the ground-air heat exchangers.
