Cross building energy exchange: legal and economic framework and influencing factors (GebEn)
Using an interdisciplinary approach, the legal, technological and economic aspects of the cross-building exchange of heating and power were analysed separately within a methodological framework which includes different system configurations relevant to the specific situation in Austria.
solSPONGEhigh - High solar fraction by thermally activated components in an urban environment
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated. The aim was to activate and use the thermal storage potential that is immanent in the building elements and thereby achieve solar coverage of the building's heat demand of nearly 100 %.
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.
Development of affordable building equipment and services for future "Energy Plus houses" (Plus-Hybrid)
"Plus-Hybrid" integrates knowledge and experience from current activities and complement them by adopting a holistic approach, considering the intelligent interconnection of components as well as managing the planned efforts and human resources in time. The goal of this project was to develop affordable building equipment and services for future "Energy Plus houses".
IEA SHC, Task Solar Thermal Plants with Advance Thermal Storage Technologies for Low Energy Buildings
Participation in TASK 32 "Storage concepts for solar buildings". Subtask leader of the subtask for heat storage based on phase change materials
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.
Potential and concepts for waste water heat recovery in combination with solar collectors and heat pumps (WRGpot)
The objective of the project is to find possibilities for the reduction of heat demand for hot water preparation of low energy and passive house buildings, in order to advance a further step into the direction of plus-energy buildings.
Ventilation and heating in passive houses: Comparison of variants in terms of thermal comfort and sustainability
This projects aims at systematic resarch on thermal comfort and the sustainability of heating passive houses with and without air heating. The results of the comprehensive investigation of different variants will provide valuable information for building developers, planners and for funding decisions.
Thermocollect - Solar active facade system, using direct solar radiation for temperature conditioning of buildings
The new Thermocollect Energy-Facade System allows to utilize the solar radiation that hits the facade on a on-demand-basis. The system works with a mechanically active mechanism which selectively gathers the solar radiation and additionally can be used as a cooling and heating system according to the local requirements.
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".
SpeedReg - Prompt quality assurance of the commissioning process of buildings
The focus of the project is on quality assurance within the commissioning process with the aim to speed up and to improve the operational adjustment of newly constructed or comprehensively renovated buildings. The fragmented know-how which is hardly accessible for the relevant target groups will be consolidated and elaborated in the form of a practice guideline which will be directly applicable in commissioning processes in practice. In this way the project contributes to the development of a common, well-established standard for quality assurance within the commissioning of buildings.
Strategy development for (technical / economical feasibility of) energy autarcic buildings
Development of a strategy for energy autarcic buildings with appropriate Technology solutions.
ThinkHome: Improved energy efficiency based on artificial intelligence in future homes
ThinkHome is a networked controlled home of the future with the ultimate goal to optimise energy efficiency and user comfort at the same time. On this way, smart interaction between all building services is of utmost importance. Goals of this project include the definition of a comprehensive knowledge base that holds all relevant building data, the evaluation of control strategies based on artificial intelligence and machine learning, as well as agent based software engineering.
DAKTRis - Dynamic operational behaviour of absorption chillers in Trigeneration Systems
In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.

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.
