This master thesis is a critical assessment of the current state of the Dom Petra Uzarja nursing home and an optimal proposal for the renewal that will satisfy not only the energy, but also the architectural aspect. In the first step, we conducted a comprehensive research review in the field of building renovations, focusing on works related to the technological and architectural solutions in the renovations of retirement homes. We made a building physics analysis of the existing construction in the KI Energija 2014 computer program and evaluated the buildings critical points. In the second step, we performed a parametric analysis of the identified critical points on the level of a typical living space, using the programs KI Energija 2014, Window 7.4, Therm 7.4 and Comfen 5. We varied the properties and surfaces of the transparent and non-transparent parts of the façade, until we came to an adequate conclusion, acceptable in terms of the aesthetic criteria and valid regulations. Based on the results obtained, we produced a proposal for an optimal prefabricated wooden façade module. We drew a typical façade zone and made a 2D analysis of its thermal field. In the third step, we presented concrete solutions for the entire building and calculated the energy consumption of the new building. In the closing part, we introduced the final findings and substantiated the chosen technical solutions.
