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.
PESI - Paradigm shift in urban energy systems through synergies with industry
Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model was created and opportunities for synergies were documented.
Site certificate
Possibilities and requirements of transferring the Swiss “2000-Watt Site” certificate to Austria
InnoGOK – Investigation of the energetic and ecological usability of solar radiation on urban spaces and paths
Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
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".
EnergyCityConcepts - Methods and concepts for the implementation of sustainable energy systems in cities
Two concrete model regions (small city Gleisdorf and urban city quarter Salzburg-Schallmoos) will be developed and tested using new methodical approaches (interdisciplinary urban and regional energy planning, modeling and simulation). Therefore, it is aimed to substantiate scenarios and concepts for the implementation of defined targets on technical, ecological and economic criteria.
ÖKO-OPT-QUART - Economically optimized control and operating mode of complex energy networks of future city districts
In the project ÖKO-OPT-QUART energy-based, economic and control-orientated models will be developed in order to simulate the operating mode of complex, sustainable energy networks in city districts. For an exemplary configuration these models will be combined to an overall model which allows a realistic economic comparison of different control strategies. The final goal of the project is the development of a method for the systematic design of cost-optimized, predictive control strategies for complex energy networks in city districts.
OPEN HEAT GRID - Open Heat Grids in urban hybrid systems
The primary research topic of OPEN HEAT GRID was to investigate the possibilities of enforcing the feed-in of industrial waste heat into existing district heating networks. The project results show that excess heat is not for free: despite minimal variable costs, the investment costs need to satisfy usual payback periods. The analysis shows that there is no need for a regulation in the sense of a feed-in obligation or market liberalization. However, from an economic point of view, information asymmetries exist, which may lead to irrational decisions.
AnergieUrban Leuchttürme: Rechtliche, organisatorische und wirtschaftliche Rahmenbedingungen für Anergienetze mit Erdsonden im urbanen Raum anhand konkreter Pilotprojekte
Für die Umsetzung der Energiewende gemäß der österreichischen Klimaziele bedarf es neuer Lösun-gen für die Bereitstellung von Heizwärme und Warmwasser in der bebauten Stadt. Die aktuellen geo-politischen Rahmenbedingungen unterstreichen die Wichtigkeit eines raschen Umstiegs auf eine nachhaltige, unabhängige Energieversorgung. Die Nutzung lokal verfügbarer, erneuerbarer Wärme-quellen in Verbindung mit saisonalen Erdspeichern stellt eine Lösung zur nachhaltigen Heizung und Kühlung von Gebäuden dar.
