This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating. The comparison aims at investigate which of the systems that will suit thehouse best, based on given conditions. Solar heating could be eliminated since the angel of the roof istoo flat. Pellet-fired boiler was deemed too demanding for the consumer since it requires constantmaintenance?something which is not desirable given that the house is designed for a family.Depending on what is combusted in the district heating the environmental impact could either beminimized or maximized, but even with the environmental impact minimized district heating is stillmore expansive in the longer run than geothermal heating. This led to that geothermal heating wasconsidered the most suitable heating system option for the house, a cheap system that requires nomaintenance and does not affect the environment.
