Abstract
This contribution reports on an ongoing research effort within the project Sim4DLG to reduce the energy and resource use in the building sector via design optimization of life cycle-oriented buildings in Austria. To reduce the heating demand and overheating risk in the cold and warm seasons respectively, a simulation-supported optimization strategy was pursued, resulting also in improved ratings in terms of the mandatory Austrian energy certificate. The application includes a range of different building types varying from stand-alone single-family houses to apartments in a multilevel building, using locally available ecological construction materials and renewable energy, with special focus on single-story atrium-style buildings. Natural ventilation scenarios were specifically explored to improve summertime thermal comfort conditions. The results are showing that the method can be used in a circular approach during the design process for reducing the overheating risk, while maintaining the passive house standard according to the Austrian energy certificate.
