Podrobno

The purpose of the thesis was to determine the necessary measures for energy rehabilitation of the building located at Tomšičeva ulica 7 in Kranj in order to reach current requirements of standards for thermal efficiency of buildings. At the same time during energy rehabilitation of the building we also wanted to apply strengthening measures with minimal interventions to increase its seismic resistance. For the analysis of seismic resistance of peripheral walls (facades) we used the FaMIVE method which allowed us to calculate the possibility of formation of the in plane collapses and out of plane collapses of the facades. The data used for the analysis was collected from in-site inspection of the building and from available documentation of the building. By mounting anchors the value of ESC factor which allow us to determine seismic resistance of facades was successfully increased for more than a double. In the second part of the thesis analysis of building’s energy efficiency was made. The data about current status of the building envelope was obtained by using thermography. We performed an energy efficiency analysis of the building with the software Gradbena fizika URSA 4.0. Results show that installation of thermal insulation onto façade, onto ceilings and replacement of old windows significantly reduces heat losses. Efficiency of heating system can be further increased by installing wood biomass boiler. The comparison of costs showed that 88 % of the whole investment represent the costs of energy rehabilitation, particularly because of the costs of the new windows, installation of thermal insulation on the facades and installation of new boiler. By implementation of measures on the building envelope we have successfully met conditions about maximum thermal transmittance trough external elements of the building, which are described in regulation PURES 2010.
