Despite the large potential for integrating large solar thermal plants into district heating and cooling networks, the share of solar heat worldwide is below 1%. The aim of this project was to analyse the technical, economic, and regulatory barriers that hinder a faster market development of such systems, and to propose solutions to support the growing heat market. The results (roadmaps, data, information) are available in the form of fact sheets.
IEA SHC Task 56 focused on the critical analysis, simulation, laboratory testing and onsite monitoring of envelope systems entailing elements that use and/or control incident solar energy. The central task was the integration of HVAC and lighting systems into a building’s Solar Envelope solution through a systemic approach.
The goal of the IEA Task participation is to further expand and integrate the Austrian scientific experts in the field of compact thermal energy storage in the international research community and participation into the expertise developed. All national participants have the opportunity to integrate the results of their own R&D projects into the Task, and enable further positioning and integration.
IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)
The aim of IEA SHC Task 59/EBC Annex 76 is the documentation of best practice examples, the development of a multidisciplinary planning process and the development of holistic reconstruction solutions for historic buildings. In addition to the lead of Subtask A (knowledge base), the Austrian participation will also incorporate and further develop results that have been achieved in national demonstration projects and have been tested in practice.
Lighting accounts for 19% of the global electric energy consumption, and major savings can be achieved by intelligently connecting daylighting, electric lighting and control systems. At the same time, optimal visual and non-visual conditions must be provided for the user. Within this project the user requirements for lighting solutions and existing and novel control systems will be analyzed and documented. For evaluation purposes a consistent scheme for the characterization of daylight systems and an hourly rating model for integrated solutions will be worked out. Using a monitoring protocol, implemented integral lighting solutions will be evaluated in lab and field studies.
The main objective of IEA SHC Task 62 is to increase the use of solarthermal energy in industry, to develop newcollector technologies and to open up industrial and municipal water treatment as a newarea of application with high market potential for solar thermal energy. The nexus between solar thermal energy and water treatment enables the development of newand innovative technology combinations and the change to a sustainable, resource- and energy-efficient industry.
Since 1977 the IEA Solar Heating and Cooling Programme supports joint research and development activities in the field of solar thermal technologies focusing solar thermal for heating and cooling of buildings, for industrial applications and in agriculture.
The Technology Collaboration Programme includes the collaboration, the exchange of relevant information and networking in the area of fluidized bed conversion of fuels applied for clean energy production.
In this annex, international Demand Side Managements projects are analysed, in which customers are automatically controlled or can adapt themselves to price changes at short notice via price signals. The most important social, organizational, economic and regulatory parameters for successful customer retention in the participating countries are identified. Furthermore, it is examined how the trust of the end customers can be built and maintained.
IEA UsersTCP: “Empowering all” Gender in policy and implementation for achieving transitions to sustainable energy
The Annex supports the design of a more efficient and inclusive energy system by integrating gender perspectives. Based on case studies and best practice examples, country-specific recommendations for inclusive energy policies will be elaborated.
The mission of the Wind TCP is to stimulate co-operation on wind energy research and development and to provide high quality information and analysis to member governments and commercial sector leaders: addressing technology development and deployment and its benefits, markets and policy instruments.
The international experts elaborated two guidelines on the current state of wind energy utilization under icing conditions: the "State of the Art Report" and the "Recommended Practices Report". On a national level, Energiewerkstatt compiled a comparative report on international approval procedures with the assessment of icefall risk, a report regarding operational experience with a stand-alone power supply unit as well as a report on the evaluation of different ice detection systems.
IEA Wind Task 19 deals with the challenges of the utilisation of wind energy in Cold Climates (i.e. under icing-conditions) and offers through global networking and mutual exchange of experience, the possibility of collecting and generating additional know-how. Aim of the subtask was to share experiences with international partners and standardising of icefall risk assessments. In addition, an evaluation report on the functionality of the new Vestas rotor blade heating system was published.
Task 19 deals with the challenges of wind power utilisation in icing conditions and provides a strong opportunity to generate new knowledge by global networking. Energiewerkstatt leads a subtask in the field of icefall risk and works on a transfer-function for converting the icing information on an anemometer to a wind turbine.
To ensure safety, reliability and productivity of small wind turbines (SWT) the experts of IEA Wind Task 27 developed a standard consumer label for small wind turbines. Since 2013 Task 27 is focussing on small wind turbines in high turbulence sites. By actively participating in the IEA Implementing Agreement Wind Energy Task 27, Austria’s stakeholders will become participants in the global small wind network. The establishment of a national working group as well as the organisation of an annual small wind conference in Austria will foster a durable collaboration and provide new impetus to the Austrian Small Wind Community.

By participating in the IEA Wind Task 27, a number of goals could be achieved, including the development of a site assessment scheme for wind turbines in areas with high turbulence intensities, the further development of the IEC 61400 standard, the participation in the “Compendium of IEA Wind TCP Task 27 case studies “And the update of the “Small Wind Power Report 2018” as well as activities such as holding the event “Small Wind Power Conference” in Austria.
Since 2012 Task 32 of IEA Wind has been concerned with the development and the multiple challenges in the application of LIDAR (light detection and ranging) applications in wind energy. The aims of this international research cooperation are the compilation of existing knowledge and experience as well as the elaboration of new conclusions through mutual exchange and global networking.
Task 32 deals with the challenges of using Wind-LIDAR-Systems and provides a strong opportunity to generate new knowledge by global networking. Energiewerkstatt elaborates an analysis regarding data availabilities of LIDAR measurement campaigns at different sites in Austria and resumes an organisational role regarding the assessment of uncertainties of LIDAR measurements in complex terrain.
IEA Wind Task 41 is engaged in enabling wind technology as an economically competitive and reliable distributed energy resource option. In order to reach this goal, extensive research collaboration is pursued and findings and results are recommended to the IEC standard review committee.
