In cooperation with a total of 22 organizations (12 research institutes, 5 universities and 5 companies) from eight countries numerous useful reports and tools have been created to improve the quality of solar cooling systems with significant contribution of the Austrian partners.
IEA SHC Task 49/IV focussed ist work on important research questions on solar process heat within the three subtasks: Process heat collectors, their application, comparison and possible standarization; Process Integration and process intensification as required interlinkage between solar heat and production processes; Design Guidelines, case studies and promotion as key for market penetration.
The focus of IEA SHC Task 51 ‚Solar Energy in Urban Planning’ has been placed on the topic of solar energy integration in urban environment. Hereby, different international examples, options and processes for planning and implementation of solar energy measures in cities throughout the world have been screened, outlined and equipped with recommendations for further development. The core outcomes of the project address different options and possibilities for optimization of planning processes, framework conditions, tools, methods and education aiming to attain more effective and timely understanding as well as integration of solar energy in urban context.
IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.
Within the framework of the IEA SHC Task 53 'New Generation (NG) Solar Cooling & Heating Systems', solar-electric and solar-thermal air-conditioning systems were investigated. The main objective was the development and documentation of reliable and economical NG system solutions. A comprehensive comparison of different NG systems as well as the elaboration of support measures for the market launch are core results of the international cooperation.
IEA SHC Task 54 was an interdisciplinary, collaborative project with the main focus on significant price reductions of solar thermal systems. Measures to achieve a reduction of the customer price up to 40% included simplified system designs, standardized components and cost-efficient materials and production and installation processes.
The growing market of solar thermal heating and cooling networks requires support in the integration of complex solar thermal systems. The Austrian project includes the management of the IEA SHC Task 55, the management of Subtask A and the introduction of Austrian project results. In the course of the research project, the integration and optimization of system components and large solar thermal heating and cooling networks are described and advanced.
This Task focuses on the critical analysis, simulation, laboratory test and onsite monitoring of envelope systems entailing elements that use and/or control incident solar energy. Integration of Solar Envelope solutions into the building’s HVAC and lighting systems through a systemic approach is central in this Task.
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.
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.
