Pasivní domy -- význam certifikace a ekonomická návratnost

In the present time, when prices of energy go up continually, we can hear more and more about the topic of energy-cutting. Important role in this sphere performs low-energy development. Passive houses, which are specific type of low energy houses, cut heat demand significantly. It means marked improvement with the view of energy saving, protection of the environment, but also quality of living. There is no doubt that these constructions bring numerous advantages, as evidenced by ever-growing number of passive houses abroad. Nevertheless, in the Czech Republic are very little passive houses. Partial intention of the thesis work is to highlight the importance of certification, which is able to contribute toward expansion of passive houses. The outcome of this part is proposal of the criteria for certification of passive houses in the Czech Republic. Principal aim of my diploma work is to compare passive house to common house in light of capital expenditures and operating costs and information about pay-off period of investment in low-energy buildings. Just matter of economic return is the most important criterion in decision making about construction of house or building.
