ABSTRACT
Do you think that passive houses are the inventions of recent years? That is not exactly true. Even if they use more advanced technology, some of the basic principles goes back several hundreds years. The History of passive houses have their roots in the 19th century, where the first building was not a building, but research ship of polar explorer Fridtjof Nansen called fram in 1883. The walls and the sandwich construction deck had a thickness of 400 mm, which fulfill the function of a thermal insulation layer of felt and the linoleum fulfill the function of a vapour barrier. The glass treated windows were triple and worked with controlled ventilation with electric ventilators. [4,7] The building, which is directly on the ground is in direct interaction with the subsoil and its thermal state. Some amount of heat is primarily destined for the creation of thermal comfort in the interior spaces from the foundational construction and the floor on the ground to the cooler sub grade. The outgoing heat represents heat losses, which unfavorably affect the overall energetic effectiveness of the building. The heat loss represents approximately 15 to 20 % of the overall heat loss of the building. This number is a clear antecedent of need of isolation and minimizes the flow of heat from
the building to the sub grade. [3,5,6]
