Project description

The expansion of renewable energy generation as well as extensive possibilities for energy storage are central cornerstones of the necessary energy transition. Thermal building component activation can be a key component here, as it can be used multifunctionally as a heating and cooling delivery system and as a storage system for fluctuating renewables. These applications not only offer enormous potential for the integration of renewable energies and waste heat, but they also promise high economic attractiveness and impress with their simplicity in implementation, operation and use.

Contents and goals

In order to accelerate the market introduction of thermal component activation in this still very new application, the service in question is intended to provide information about the performance of the storage and energy flexibility potential on the one hand, and to generate essential findings with regard to user comfort, user satisfaction, economic aspects in construction and operation as well as functionality of the process flows on the other.

The 18 selected component activation demonstration buildings are characterised by a high degree of diversity, e.g. harmonised regional distribution, different building uses and sizes (residential, office & administration, accommodation, education, manufacturing, warehouse, etc.), different construction methods and activated materials (concrete, brick, wood, clay), different ways of integrating renewable energies and different initial situations (new construction, renovation of existing buildings).

In the course of at least one year of monitoring, the project team will, on the one hand, deal intensively with energy balancing and the recording of temperature profiles and, on the other hand, devote itself to the question of comfort and user comfort. In addition to energy and comfort monitoring, a survey and analysis of the subjective satisfaction of the building users will be carried out. Interviews with stakeholders (investors, planners, contractors) round off the creation of a comprehensive and well-founded knowledge base.

Expected results

The findings and recommendations will be summarized in a comprehensive publishable study and additionally aggregated in a special form (e.g. as a guide) for potential decision makers. Furthermore, the findings and conclusions are presented and discussed in the context of results workshops.
