Economic Advantages and Disadvantages of Passive Houses in the Czech Republic and the European Union

Subject of this thesis - Economic advantages and disadvantages of passive houses in the Czech Republic and the EU - is very topical with regards to building boom and the environment and related issues of energy-saving housing. Comparison of economic advantages and disadvantages between passive houses and low-energy buildings is also interesting considering connection modern, comfortable and environmentallyeffective housing. Reducing the energy performance of buildings is currently a fundamental trend and an opportunity for the future, either for individuals as well as for society. It is the result of international legislation dealing with the energy performance of buildings, which is addressed by Directive 2002/91 / EC of the European Parliament and Council of the energy performance buildings. The main target of the practical part of the bachelor thesis was to evaluate the return on investment in passive and low energy houses. The starting point of the calculation is the specific energy consumption for each type of house that is defined by the standard. The main benefit of this work is a finding based on the annual operating costs, which combined with the amount of the initial investment was calculated by the return on investment. This is 19 years for passive houses, which is lower than for low energy houses (28 years). This difference is influenced by the two main factors, namely the "Green Savings" subsidy for passive houses and the energy efficiency of passive houses. The calculation has taken into account the current and constant energy prices. It can be assumed that energy prices will rise in the future, making the investment return differential between passive and low-energy houses even more pronounced. The results of the return on investment are also consistent with those reported by different suppliers and developers
