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.
