SYSPEQ - Systemische Lösung zum Betrieb von Plusenergiequartieren

Full-scale planning concepts for positive energy districts (PEDs) and their operation as energy communities (ECs). The focus is on the implementation in the existing building stock, especially in the area of social/non-profit housing. Financing options for renewable generation units, planning and operation of a PED (especially as an EC), marketing opportunities for surplus electricity and the development of an information and networking platform are part of this project. A special highlight is the practical proof-of-concept in Fuchsenloch, which is a social housing quarter of Sozialbau.

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.

The Box - Thermal High Performance Decoupling - Next Generation Thermal Break Technology

The project pursues the overall strategic objective "solution of the problem-inducing heat bridge". For this purpose, the thermal bridging losses should be reduced by the factor of 15 in contrast to the state of the art. The significant increase in efficiency should rely on existing system solutions, but incorporating a new holistic view in terms of construction, geometry and materials.

The Green Parking Space – Utilization of urban parking areas for production of biomass

Many traffic areas in urban environments are actually used as such only a small fraction of the time. Subject of this project was to investigate the possibility of using those areas by additional integration of photobioreactors for the production of biomass, integrating such systems to the maximum extent into the urban substance and energy cycles.

urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy

The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.

Urban wind energy - Development of methods for the assessment of small wind turbines in urban areas

The project "Urban wind energy" aims to create the basis for the assessment of roof-mounted small wind turbines (SWT) in urban areas. Therefore, methods for the characterisation of turbulent wind flow fields are developed and on the other hand the impacts of turbulent wind conditions with reference to selected turbulence indicators on the performance of small wind turbines are investigated. The overall aim of the project is to address the question how to evaluate sites in urban areas for the application of small wind turbines.
