Renewal of Panel Residential Houses from the Point of View of Energy Criterion

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.
