Energy efficiency of housing stock as an economic incentive to increase the performance of real estate objects

The most possible increase of market value after large-scale reconstruction can be reached when a building or a group of buildings are situated in rather economically attractive areas, while the most part of the area is already repaired. In these cases the costs of repairs can be compensated by means of increase in the market value and sale of additional floors. The wide use of more effective methods of construction can also increase the price in the repaired real estate objects. The influence on the economic value of houses and buildings can be considerable also due to the improvement of operational qualities and because of an esthetic component. The opportunities for substantial increase of energy efficiency in economic sense are directly connected with the needs for large-scale reconstruction of the outdated building. Nevertheless, the changes of just windows, repair of facades, etc. lead to reasonable improvement of power efficiency, and respectively and building costs in general. The use of natural resources in construction during repairs of the building and at the stage of operation influences the environment. The influence degree depends not only on isolation, but also on the choice of the type of repair, energy efficiency, front and roofing materials, and also on the use of energy raw materials, necessary for construction process
