Passive house

Passive House is a house building concept combining high-level comfort with very low energy consumption. The key elements of this concept are thermal windows constructions, high-level heat recovery and insulation of airtight building envelope, as well as controlled air exchange between indoor premises and the outside. Each “passive” house is a contribution to environmental protection. From the other side, a Passive House does not essentially differ from conventional buildings, except that it is built in accordance with the highest standards.
