Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods. Tendersby established energy companies in Sweden were used as input data to form different alternatives for each building. From the comparison between the selected LCC-models, both similarities and differences were identified. The differences vary both in scale and how they affect the result. Nonetheless two of the models show the same results for some of the alternatives. In order to approximate the environmental effects for each heating and cooling method, carbon dioxide emissions were compared. The conclusion of this report is that while there are significant differences between the different LCC-models, the results only differ marginally for most models.
