Sol2Pump - High efficient combination of solar thermal plants, photovoltaic and heat pumps
Targeting a high level of decentralised energy supply on basis of renewable energy, the project analysed the possible combinations of solar thermal energy, photovoltaic and heat pumps. The project aimed to maximise the domestic energy supply due to utilisation of the building as short term energy storage. In addition to that, several optimisation measures had been developed. The impact on the energy supply and demand will be economically assessed through life cycle costing. On this basis, the potential load transfer and the use of this kind of systems had been evaluated in combination with smart grids.
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.
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.
Increase of in-house consumption by building clusters and active storages (Eigenlast Cluster)
The project involved the evaluation of the significance of new approaches for the increase of in-house consumption of solar energy (electric energy and heat) of buildings in Großschönau, which are already equipped for such measurements. The existing municipal buildings, commercial buildings and households are aggregated to form virtual building clusters. Subsequently, the clusters were analyzed according to their in-house consumption with and without the usage of batteries and H2 storages. The economic analysis of this concept derives from a regional implementation plan for further industrial research.

Certification of straw bales as insulating material, development of a straw bale logistic concept and a quality management system as strategic measures with the aim of the dissemination of straw bales as insulating material
MOTIVE – Modeling, Optimizing, and technical integration of Vacuum-Glazing-Elements
This project addressed the development of construction details for the implementation of vacuum glazing panels in new windows. In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
"Communal living for elderly - ecological, social and economical aspects" - eco-com.60+
The research project examined different forms of communal living of elderly people and contributes to the development of new, common forms of living for the elderly. Questions concerning demographic change and economic as well as ecologic challenges of our time had been dealt with.

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.
