This graduation thesis presents the study of the energy renovation options for residential
building, located on 8abc Cesta 9. avgusta in Zagorje ob Savi. Firstly I discuss currently
active legislation concerning energy consumption. Secondly I give a short presentation of our
building of interest and I calculate current energy balance. Building is energy inefficient,
therefore I propose different measures to improve energy efficiency. I analyse proposed
measures from the point of their efficiency and feasibility. I also analyse and comment
different combinations of proposed measures. I suggest a combination of measures, that
makes our building of interest energy efficient, as defined in currently active legislation.
Some combinations reduce annual heating requirements by more than 80 percent and the
most efficient combination reduces it by 88.5 percent. At the end I discuss the use of
renewable energy sources with focus on heat pump and photovoltaic modules.
