The fair of CEP CLEAN ENERGY & PASSIVEHOUSE moves the passive use of energy even more into focus what makes a building a passive house? Who craves for its comfort, is often forced to heat in the winter and in the summer to cool not infrequently with high energy consumption. Passive houses are different. You use the natural energy, so the natural warmth of the inhabitants, as well as the sunlight, to ensure pleasant temperatures in the cold season. The necessary well insulated building envelope at the same time ensures not too heat up the rooms in the summer. This principle works fine. It is economically attractive and environmentally sensible.
No wonder that more and more building owners that are interested in. The international trade fair for renewable energy and passive house CEP CLEAN ENERGY & PASSIVEHOUSE 2010, which will take place from 25 to 27 February 2010 in the Stuttgart Exhibition Centre, is therefore consequently the passive house more the focus in the exhibition as well as accompanying congresses. According to definition, those buildings are known as passive house, which come out in winter almost without additional heating and in the summer without air conditioning, thereby creating a high degree of comfort with low energy consumption. When a heating demand kWh/(ma) and a heating capacity of up to 10 W / m sq is called by maximum 15 a passive house\”. And how is heated? Every person emits heat.
This and the radiation of the Sun rich almost from heats to keep the House warm to a passive house so passively\”on. The ventilation is controlled via a system which ensures by means of efficient heat exchangers, no warm exhaust air is lost. Passive houses are characterized by windproof, very well insulated and possible thermal bridges-free building shells. These ensure that the heat losses compared to conventional buildings by up to 90 percent are low.
