Possibilities of reducing the energy demand of a family house within the NZÚ program

This bachelor's thesis focuses on the energy and financial savings, which are key interests of today's society and closely linked to the measures described in this thesis. The theoretical part provides detailed explanations of the key concepts related to the topic. Subsequently, attention is given to improving the thermal-technical properties of houses and identifying technological procedures for reducing the energy demands of buildings. An important part of the theoretical part is also a description of the subsidy programme called „New Green Savings“. In the practical part of the thesis, the operating costs of the house and the costs of implementing three possible insulation measures for the envelope masonry and the window and door filling in order to improve the thermal technical properties of the building are quantified. Energy performance certificates (PENB) are prepared for both the current state of the house and one of the proposed variant. The work also includes a quantification of the subsidies that can be obtained after the implementation of the measures and a subsequent analysis that could lead to an increase in the subsidy amounts. Finally, the payback period of all investments made is calculated
