Comparing invest to save heating

The purpose of this bachelor thesis is to compare invest to save heating of a sample family house. At the beginning of the thesis there are analysed some individual options for reducing energy efficiency of the house. There are also discussed disadvantages of thermal insulation if it is badly performed. Thereafter there were calculated the heat losses of the house according to standard ČSN EN 12831, which determined the total annual energy demand for heating. These calculations were repeated in the software TechCON®, in which was later solved individual proposals to reduce the heat loss of the house. In the end, all options were evaluated
