THEBAVOL - Applications and limits of thermal component activation in large-volume multi-storey construction

Thermal component activation (TCA), a technique in which reinforced concrete components can be used both for heating and cooling buildings by supplying or withdrawing heat, represents a high usable storage potential for implementing the energy transition and can be optimally combined with volatile forms of energy.


The applicability of this technique has already been investigated in several successful research projects („Thermische Bauteilaktivierung. Entwicklung eines Rechenkerns“, F. Friembichler et al. 2014, „Energiespeicher Beton“, K. Krejc, 2016). Demand for this technology is rising, especially in large-volume residential construction, where two projects are being implemented in Vienna, for example.
The number of experts with planning and execution skills or relevant experience in the field of TCA, especially in combination with the dynamic management of storage facilities, is currently still low. In order to promote the spread of this technology, it is essential to increase the number of competent planners and consultants in this field. Particularly important target groups here are architects, building services planners and energy consultants. These groups were therefore given special consideration in the selection of the companies involved.
A primary qualification goal is the development and deepening of competences for the planning and execution of the use of TCA in large-volume multi-storey construction with special consideration of the optimal use of volatile forms of energy. The participants, who are recruited from the fields of architecture, building services and energy consulting, should, in addition to deepening their planning skills, also acquire sufficient didactic and technical skills to act as multipliers in courses to impart the knowledge necessary for the planning and implementation of TCA to relevant target groups.
