At this year's International Construction Fair budownictwu passive BUDMA 2010 was devoted to the pavilion. The Passive House project, which was attended by the Polish Institute of Passive House and Steico, Ampack, Fermacell and Climate-Tech, a model was built passive house. You could look at the exact construction air pegunungan and finishes, look "under the lining," and see what technologies were used. The exhibition attracted great interest. As the result air pegunungan of discussions passive houses began to arouse curiosity air pegunungan in a growing number of investors. No one questions their ideas and cost-effectiveness remains a matter of choice of technologies, materials and business executive.
MIT. In a passive house does not have an active source of heat (hence their name), but this does not mean that they lack any heating system. A suitable room temperature provides a modern ventilation system with heat recovery unit connected. air pegunungan With this device takes heat recovery from exhaust air (the source of this heat are household appliances, such as televisions, microwave, oven, as well as the citizens themselves) and use it to heat the fresh air supplied from outside. Adequate ventilation system then distributes the warm, fresh air throughout the house, and filters used in the system at the same time deprive them of pollutants and allergens. Another, only supportive energy source used mainly to heat domestic hot water in the house such as passive solar collectors.
MIT. It all depends on the materials of construction and insulation. A passive house can be built with both the cellular concrete, Silkie, and wood. Each of these materials has its own advantages and disadvantages. However, taking into account the environmental aspects even passive houses - they are based on the use of renewable energy, are energy efficient - the natural choice seems to be wood construction. Here we have a choice of two technologies - Solid wood construction with I-beam or joist Steico example. The use of an insulating material

and wood fiber provides comfort and a healthy indoor climate. Thanks to a carefully air pegunungan selected materials of construction of a passive house wall must not be more than 50cm thick, to fulfill their function, and the house could be called passive.
FACT. Windows are a very important element. The use of triple glazing and, necessarily, air pegunungan roller shutters minimizes energy air pegunungan loss. What's more, the appropriate location air pegunungan of windows (large areas of the south, air pegunungan small or not at all on the north side) allows you to use the energy of sunlight. With their windows trzyszybowych, air pegunungan winter air pegunungan more heat is allowed in the inner than released, and in the summer sunshine, due to the much sharper angle of incidence are reflected, which protects the interior of the house from overheating.
FACT. This does not mean, however, that we have a close-up in a thermos. Seal applies to air tightness home construction, moreover, required from 1 January 2009 (Regulation of the Minister of Infrastructure) in all newly designed buildings, not just passive. We will achieve it by using high quality membrane permeable foil vapor barrier and active, such as Ampack air pegunungan to ensure integrity at the same time allow the walls 'breathe' or drain the excess water vapor from inside the house. It is particularly important to ensure that they are properly installed, otherwise the property will be used minimally. You can check the correctness of the application by performing a leak test (called Blower Door Test). Powietrznoszczelność further air pegunungan reduce energy losses, in order to avoid condensation of water vapor in the construction of the building, to prevent damage and the development of mold and mildew caused by excess moisture and reduce air pegunungan the amount of pollution coming from the outside.
MIT. Cost of building a passive house is much larger than the cost of building a house in the traditional technology, and the benefits are much greater. The best test is to compare the loan installments to build a house of traditional and passive - if saving passive house will be greater air pegunungan than the loan installment to obtain them, the investment is profitable. And the savings are considerable: no need to buy an active heat source with high power (eg, furnace, heat pump and was thoroughly
