A complex renewal of residential houses is a renewal of flats and common areas of the house so that they meet effective regulations and standards. Most of the residential houses in Slovakia built during last sixty years fall into the category of panel systems. An important criterion for determination of the extent of renewal of panel residential houses is required specific energy need for heating (energy criterion) and proving of precondition of satisfaction of energy economy of a building (criterion of minimum requirement on energy economy of buildings). In connection with the effect of new standard STN 73 0540:2012, the requirements for building constructions and buildings changed. Therefore, the residential houses of panel systems were evaluated in this paper from the point of view of the energy criterion both in original state and after the renewal by adding thermal insulation on walls, roof and replacement of windows.

The paper presents calculated values of increase of thermal transmittance because of thermal bridges (ΔU value) of panel residential houses of mass housing development. These values are compared with general values, which are given in the standard STN 73 0540-2 and afterwards a specific energy need for heating considering exact ΔU values but also general ΔU values was calculated as well. The residential houses were evaluated in original state and in state after the renewal by adding thermal insulation on walls, roof and after replacement of windows.

Thermal Bridges

In a general sense, it is possible to say, that panel houses show considerable defects. Many of them results from insufficient thermal protection. At present, these buildings fail to meet the requirements from the point of view of neither thermal insulation properties nor hygienic criterion (Slovak Standard STN 73 0540-2:2012). This shortcoming manifests itself not only in large consumption of heat for space heating, but also in functional and hygienic shortcomings of envelope constructions (formation of moulds). The paper deals with a thermal technical analysis of selected critical details (thermal bridges) of envelope constructions of panel residential houses in original state and in state after adding thermal insulation.

The submitted article deals with a relatively new phenomenon, which is monitoring and solution to minimization of microorganisms ́ occurrence on the surface of the External Thermal Insulation Composite Systems (ETICS). The importance of the solution has been becoming more important both from the point of view of health risk for inhabitants and accelerated degradation of particular layers of the ETICS due to the presence of these microorganisms. The article submits conceptual methodological solution to the reduction of count of microorganisms on the ETICS surface from diagnosis, setting out criteria for the necessity of determination of macrobiotic biodeteriogens to subsequent rehabilitation design.

Abstract Based on cartographic materials, three lakes drained in the previous centuries have been reconstructed. It was found that by restoring them to their original state their total surface area would rise by 140 ha. Knowing the water surface level, determined on the basis of the range of peat soils and contour lines, the author reconstructed the bathymetric plans of the lakes. This, in turn, allowed a determination of the volume of water stored in their basins. It amounted to ca. 2.5 million m3. The approach adopted in the paper draws attention to an important element, i.e. to lakes which no longer exist in Poland and which have disappeared as a result of hydrotechnical works. Their restoration to their original state could become an important link in water retention and delaying the land phase of the water cycle. Activities aimed at retaining water in reception basins are carried out in Poland, among others, through the small retention program. Within this project, facilities such as artificial storage reservoirs are being built. In the light of the foregoing, before making a decision to build such a reservoir, it is worth considering the possibility to restore the natural components of the environment, which is more justifiable, both from the point of view of subsequent functioning of the environment and economic factors.
