Summary

In this paper the analysis of implementation of energy saving measures in an existing residential building was conducted. Simulation of the energy behavior of the residential building, with useful heating area of 1247,68 m2, was performed by using software EnergyPlus. Six proposed measures was analyzed: replacement of windows and doors (case 1); change of the roof construction (case 2); change of the ground floor and ceiling constructions (case 3); change of the interior walls between different users (case 4); change of the interior walls toward unheated space (case 5) and implementation of all previously mentioned measures (case 6). The simulation results indicate that the average savings of heating energy of analyzed building are, respectively: 12,71% (case 1); 9,35% (case 2); 5,2% (case 3); 0,56% (case 4); 2,04% (case 5) and 29,37% (case 6). For reconstruction of all building constructions in order to achieve the value of U - coefficient that meets the Regulations on energy efficiency of buildings, a large investments are needed. In terms of investments the best solution is related to the change of the roof construction. This paper is a part of investigation that is related to the analysis of heating consumption in heated apartments during the reduction of air temperature or unheating of adjacent apartments of an residential building.
