The global climate change causes extreme weather conditions and poses a major challenge for architects, civil engineers and building physicists. Thermal comfort in buildings is becoming increasingly important, especially in the transition and summer months. klimaaktiv (the climate protection initiative of the Austrian Federal Ministry for Sustainability and Tourism) attaches great importance to thermal comfort, energy efficiency and ecology of residential and non-residential buildings. That is also represented in the respective klimaaktiv criteria catalogs for building certifications. Within the framework of the klimaaktiv regional partnership, the Upper Austria University of Applied Sciences compared various evaluation methods for proving the summer suitability of different types of buildings. In this context, some serious deviations in the results of the different valuation methods were identified. The fact that one valuation method ensures the thermal comfort of a building and another proves the opposite can lead to serious problems and legal issues. Furthermore, the differences between solid and light-weight building construction in terms of room temperature and the necessity of shading measures and innovative air ventilation concepts have been demonstrated. The validation of the results by means of dynamic building simulations, carried out with IDA ICE, is the subject of further research projects.
