Talk: Sustainability in the built environment for climate change mitigation, Thessaloniki, Greece; 2019-10-23 - 2019-10-25; in: "SBE19 - Sustainability in the built environment for climate change mitigation", T. Theodosiou, K. Tsikaloudaki (ed.); (2019), 128.

This contribution reports on an ongoing research effort within the project Sim4DLG (FFG 853842) to optimise the performance of life cycle oriented buildings in Austria. For a reduction of the
heating demand and overheating risk in the cold and warm seasons respectively, a simulation supported optimisation strategy was pursued. This approach is applied to a range of different
building types, varying from stand-alone single family houses to townhouses and apartments in a multi-storey building, which are to be constructed within the project Life Cycle Habitation (LIFE13
ENV/AT/000741). To avoid overheating risk in the buildings and to increase the thermal comfort, the dimensions of external shading devices were investigated, especially in combination with
summer-time natural ventilation. Apart from the exploration of the indoor environment of each building type, the heating demands of the buildings were specifically examined. This includes a
comparison of the building parameters and simulation procedures as well as an evaluation of the outcomes and deviations of the simulation results in relation to the concurrently calculated
mandatory Austrian energy certificate. The simulation results suggest that this strategy has not only the potential to improve indoor conditions, but also to result in better ratings in terms of the Austrian energy certificate.
