The aim of this thesis is to create an energy simulated model with IDA ICE (IDA Indoor, Climate and Energy) of a multy – family apartment located in Andersberg, Gävle and then validate the model against measured district heating. The model will be used in future renovations by the property owner AB Gavlegårdarna and involved consultants to investigate energy savings measures. The district of Andersberg is located 4 kilometers south of Gävle City. The studied construction is a five-floor multi-family residential building with about 50 apartments. It was built under the Swedish Million Programme which had its constructing period during 1965 – 1974 century. These buildings need renovation and energy efficiency. Sweden has implemented several goals, including reducing the total energy use per unit of floor space in residential and commercial buildings with 50 % until 2050. In order to execute this study, a preliminary investigation, site visits, measurements, literature study, calculations and energy simulation were accomplished. The research method that is used for this thesis is a case study used by simulation of a building where a calibrated model against measured data for energy use is created. By calibrating simulation models, it gives a better model that matching the real building operating performance. An energy signature method performed by Martin Eriksson, who is a postgraduate of energy systems, is used to validate the building loss factor. The calibrated model can later be used to identify and estimate energy saving measures. An evidence-based method is applied to maintain choice of important data for build energy simulation. These selections are used for input parameters when creating the model and are based on the priority order in a defined source hierarchy. The results of the study achieved where not to pass a difference of 10 % between simulated result and measured data. The simulated needed district heating energy for the building deviate only with 5 % against district heating energy received from Gävle Energi. The buildings facility electricity and household electricity were taken from energy declaration for the building and Svebys standardized values for using calibrating. It is resulting a difference with 7 % respective 1.2 % between simulated and calibrating data.
