In this thesis, three different single-family house types were meticulously studied with the aim of improving energy efficiency through a variety of measures. These measures were identified, simulated, and combined to create specific action packages for each single-family house type. The individual measures simulated using BIM Energy software included basement wall insulation, exterior wall insulation, attic floor insulation, window and door replacements (only for house type 1, as other single-family houses had already undergone these replacements), installation of FTX ventilation, and installation of solar panels. After simulating the individual measures, three distinct action packages were created by combining the individual measures. The results demonstrated that the action packages had a positive impact on energy efficiency and influenced various aspects, such as energy performance, heating, energy losses, and the U-value. The three created action packages were designed to improve the building envelope and energy performance. Action Package 1 consisted of FTX ventilation, exterior wall insulation, and window and door replacements. In Action Package 3, FTX ventilation, attic floor insulation, and exterior wall insulation were combined, with the combination for single-family house type 3 being the same as that for single-family house type 2. Simulations revealed that single-family house type 2 was the only one that met the energy performance requirements according to BBR 29 after implementing the action package. Single-family house types 1 and 3 did not fully meet the energy requirements, but they came close to compliance after implementing the action package. As for the U-value, it was only met in house type 2 when implementing individual measures, specifically exterior wall insulation. Single-family house type 3 came close to meeting the requirements, while single-family house type 1 required substantial improvements to comply with the standards. In summary, this research highlights the importance of selecting the right measures to enhance energy efficiency in single-family houses, with specific measures tailored to each single-family house type.
