【 摘 要 】

This paper presents results of a parametric study, which analyses the energy demand of a family house. Assessed house has various shape factors and the thermal-technical properties of the building envelope. Also the recuperation unit and the heat source is taken into account. The house in the first case is a one story bungalow, the next version is a partly two story house and in the third case it is a complete two story house. Each of these geometric variants is calculated for four various building envelopes, which are considered for different energy performance standards including low energy and passive standard. Air exchange rate is considered according to the Slovak standard as natural or mechanical with use of recuperation. As heat sources are considered gas, heat pump, pellets, electricity and wood. Also two combined sources are analyzed: gas and pellets with solar collectors for preparing the hot water. The results are analyzed according to the Slovak standard and directives, which are in terms of delivered energy, primary energy and CO2 emissions.
