An energy calculation model for Swedish houses that is fast, flexible and user-friendly has been developed within the framework of this thesis. The model also provides a set of actions which may be investigated in the model based on savings and payback period. Energy use in a house depends on the technical conditions, such as building envelope and heating systems, which outdoor climate the house is exposed to and who lives in the house. Energy use for a house can be divided into heating, hot water and household electricity. There are several methods to calculate the energy use of a house. This report summarizes the methods that may be suitable for a fast and user-friendly calculation model. Various energy efficiency measures as may be appropriate for a house are described in terms of cost and savings perspectives. The analytical model includes a model that calculates the use of household electricity, based on the residents of the house. The household-electricity model is based on raw data from a survey of 400 households conducted by the Swedish Energy Agency. A sensitivity analysis has been made in the energy calculation model, which gives a sensitivity of about 18 percent. Of the total sensitivity more than half (10 points) consists of the sensitivity of the indoor temperature and efficiency of heating systems.
