SeasonalGridStorage - Innovative seasonale thermal storages for urban district heating grids

Sensible storages, which are currently used in district heating networks for seasonal storage of excess heat (e.g. from solar thermal or industrial waste heat), exhibit high space demand, investment costs and heat losses. Within this project, concepts for using innovative storage technologies, e.g. thermochemical storages (TCS) having high heat densities and enabling pressure- and lossless storage, were developed and analyzed on a technological, economic and ecological basis. Additionally, the regulatory framework has been evaluated.

TFlex - Temperature-flexibilisation in low-load operation of local district heating systems

Within the research project TFlex it was checked if the losses adherent to small district heating networks during low-load periods can be reduced. One possible solution is by deactivating the network and supplying the customers from previously charged decentralized storages. The optimal clustering of the storages and the possibility of solar-charging the storage were calculated with the aim of a guaranteed one-hundred percent heat supply.

EDEN - Developement of a structured data and preparation documentation with a minimized error-proneness for energy performance cerificates.

Current energy performance certificates hold major flaws. Therefore, the presented research initiative aimed at the development of a standardized and easy-to-use, generic Input-Data-Documentation, which ensures the quality of energy certificates for all involved stakeholders. During the development, the documentation had been conducted and for a chosen sample of representative buildings, which is expected to demonstrate the high potential of such a development.

PEAR – Test facility for energy efficient automation and control of buildings

The energy demand calculated in the design phase often differs from measured values in the actual building operation. This projects reviews building automation and operation by presenting a solution how to assess energy efficiency of control strategies in the fields of air conditioning systems, concrete core activation and free cooling. The results are implemented in the demonstration building "Post am Rochus".

P2H-Pot - Potentials, economic feasibility and system solutions for Power-to-Heat

P2H-Pot has identified economically feasible potentials for Power-to-Heat (P2H) in urban regions. The suitability of different technical system configurations were investigated using thermodynamic simulation and considering experiences from Scandinavian cases. The assessment of short, medium and long term relevance and economic feasibility of P2H were accomplished by simulating model-based scenarios up to 2050 of the Austrian and German electricity and heat market. In cooperation with a district heating company three case studies have been carried out.
