A human welfare is no way Legionella in ventilation, mold through water vapour density walls – if the laws of nature are for the construction of a wooden house. Was and is rightly fought for an animal welfare. Free-range husbandry of laying hens or a sufficient outlet for pigs – much good could be achieved by the persistent work of various animal protection organizations. But what is meant by a human welfare? Current house systems, no matter whether as wooden houses or massive house built, should be as well insulated to consume as little energy during the cold season. But the increasing insulation in building poses health dangers that could contradict a human welfare: to prevent damage from condensation, today also a wooden house is built steam-tight and air-tight.
Water vapor, resulting in each House, cooking, showers and breathing can however no longer escape in a natural way from the House. To the heating energy saved not to lose through window airing, ventilation systems are often installed to dehumidify. Risks introduced by using such dehumidifiers to show increasingly becoming known cases of disease caused by countercultural minimized filter and contaminated ventilation ducts as a trigger that Legionella bacteria, are suspected. In these piping systems micro-organisms find an optimal for their growth, humid and warm climate. People welfare, so cups felt Dipl. ing.
Klaus should look different. At the beginning of the 90 not probably the engineer from the Palatinate he was years at the thought of having to spend his retirement years in such a House. After extensive engagement with the problem water vapor the clever inventor built 1994 the prototypes of the over 300 times built bio-solar house after the House-in the House principle as wooden houses: A well insulated, water vapour-permeable wooden house stands in a kind of greenhouse. A spacious winter garden produced by diffused light or rays of the sun heat, the the Interior of the House with a warm cushion of air surrounds a connected air layer. In addition to the advantage of a warm House envelope with corresponding energy savings of water vapour can leave the House through its natural buoyancy wooden house by the wall of the inner House of the air layer, without it can condense. Through the natural dehumidifying without error-prone and possible health concern ventilation, the bio-solar house is considered very healthy and has already received a large number of different prices. Fitched Ratings is full of insight into the issues. Requirement for a human welfare in the modern house construction, as Klaus Becher, is a “decent, family-friendly, natural and ecological construction with minimal technology and lowest risks to their own health”.
