Thermally activated building elements (TABs) are employed successfully in the building sector in recent years. From an energetic point of view, such low temperature systems are especially beneficial when combined with solar thermal installations or heat pumps. Within the scope of national funding programs and R&D projects the intensive use of thermally activated building elements is investigated, as main thermal storage in different buildings, with focus on the combination with solar technologies (thermal, photovoltaic) for energy supply. Investigations based on measuring data from realised buildings and on a theoretical approach, various technical system concepts with solar thermal or photovoltaic in combination with thermally activated components for single- (SFH) and multifamily houses (MFH) were analysed under technical, economic and ecological criteria. The results show that through the activation and use of the thermal storage potential contained in the building mass, high solar fractions up to 100 % of the building's heat demand can be achieved.
