User friendly model for energy savings : A tool which helps owners of one-­‐to-­‐two family dwellings reduce their energy costs

Energy awareness is growing among the Swedish population and a one­‐to­‐two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs. The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model. A prototype running the operating system iOS is created and validated against existing models, as well as an energy audit.
