In the first part of this thesis I made an analysis and energy balance of an apartment building in Tolmin, which was built more than a hundred years ago and converted into an apartment building in 1989. In the analysis I concentrated on the state of thermal, acoustic and hydro protection of the building and checked their appropriateness compared to currently valid legislation. For this purpose I used programs Ubakus and Hrup13. I gathered the information about the structure of the construction systems and materials used from the project documentation needed for issuing a building permit. The effect of the current state of the building envelope on the living environment was also described in the analysis of the building. Program KI Energija 2019 was used for the calculation of the energy balance. The results of the energy balance are commentated upon and compared with the currently valid legislation.
In the second part, an example of a renovation is presented and an energy balance of the renovated building is calculated. All structural changes of the building envelope and new materials used for the renovation are described in the example of renovation. The effects of the changes on the living environment are also described. In the end, the energy balance of the renovated building was made.
