IEA SHC PVT Task 60: Applications of Photovoltaic/thermal (PVT) Systems and New Fields of Application and Examples of PVT
The objectives of the task are the development of new system solutions, where the (Photovoltaic/thermal) PVT technology has clear advantages over the separate installation of PV modules and solar thermal collectors as well as standardization and cost reduction. The Austrian participation serves the establishment and deepening of know-how, the strengthening of the international network as well as the transfer and optimal conversion of the task achievements for the Austrian industry.
The goal of the Annex Electric Motor Systems is to raise awareness on the large savings potential in motor systems, while showing the realization method of such a path. After publishing the „Policy Guidelines for Electric Motor Systems“ and recommendations for carrying out energy audits for motor systems based on international standards Austria will analyse the impact of industrial automation on electricity consumption and the motor market.
The project aims at enhancing the acceptance of heat pumps and removing market barriers by reducing acoustic noise emissions and vibrations. The project involves: innovative experimental laboratory work, various numerical approaches and preliminary work in context with uniform legal and normative boundary conditions. In addition, new assessment schemes are developed and perceptual tests are carried out.
A dominating concept to reach a nearly Zero Energy Building (nZEB) is the combination of solar PV systems and heat pumps. The extended scope of the Annex 49 regards the balance of single buildings and groups of buildings/neighbourhoods, a thorough investigation of heat pump integration options for nZEBs and nZE neighbourhoods by means of monitoring and simulation as well as the design and control optimization for heat pumps in nZEB and the integration into energy systems.
Clusters of public buildings like hospitals or university campuses often include critical infrastructure which relies on sufficient energy supply. The Annex aims at developing tools for the planning process of resilient, efficient and low carbon energy systems for such building clusters.
The requirements on building envelope and on building technology are steadily increasing. There is a lack of monitoring and analysis methods to control the quality of the built implementation. The objective is to provide methods for an on-site (in situ) assessment of the actual energy performance. Based on the results from EBC Annex 58, this Annex takes the step towards practicable characterization procedures.
The construction sector has great potential to reduce its energy consumption and the associated environmental impacts. The IEA EBC Annex 72 therefore focuses on the harmonization of methods for the assessment of construction-specific and operational environmental impacts (primary energy requirements, greenhouse gas emissions and otherindicators) throughout the life cycle of buildings.
IEA EBC Annex 75: Cost-effective Building Renovation at District Level Combining Energy Efficiency & Renewables
For the transformation of existing buildings to nearly zero energy buildings with low greenhouse gas emissions it is important to know which strategy is most cost efficient to reduce primary energy demand and greenhouse gas emissions of the buildings. Especially the right balance between renewable energy measures und energy efficiency measures is of high importance. To give an answer to this topic is goal of this project.
IEA SHC Task 59: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)
The aim of Task 59 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.
IEA SHC Task 53 ‘New Generation (NG) Solar Cooling & Heating Systems’ investigates system concepts for solar electric and solar heat driven cooling and heating processes. Its main goal is the development, documentation and assessment of reliable and economically viable photovoltaic and/or solar heat operated cooling and heating systems. A comprehensive and comparative report of various NG systems and a description of support measures for their market introduction are key results of the international cooperation.
Lighting accounts for 19% of the global electric energy consumption, 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.
IEA IETS Annex 17: Membrane filtration for energy-efficient separation of lignocellulosic biomass components
Overarching goal of IEA IETS TCP Annex 17 is to strengthen the network of the Austrian membrane and biorefinery landscape. The aim is the optimized use of lignocellulose material in biorefineries by using efficient and sustainable membrane technologies. Regarding this, energy efficient membrane technologies are evaluated, optimized as well as strategies for the utilization of biomass components are developed.
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.
ISGAN aims at enhancing the knowledge about Smart Grid Technologies and accelerating their international development. The main objective of the Austrian participation in IEA ISGAN Annex 6 is to acquire knowledge and develop long-term concepts for the development of an intelligent electricity system, with the focus on the interaction of distribution and transmission networks.
Annex 70 will focus on identifying, reviewing, evaluating and producing leading edge methods for studying and modelling the building stock including: data collection techniques on energy use, building features and building morphology; analysis of smart meter energy data, building systems, and user behaviour; and modelling energy demand among sub-national and national building stocks.
Task 31 is a research and development oriented Task with the objective to contribute to the identification and development of techniques and materials to reduce the cost and improve the durability of polymer electrolyte fuel cells (PEFCs).
The aim of Annex 35 is the information exchange on the status and new developments of portable fuel cell systems and comprises the development and manufacture of membrane electrode assemblies (MEAs) all the way through to system components such as electronic converters or gas supply units. In addition the setup and configuration of hybridized systems and the key topics of secure operation, codes and standards are of interest.
The technology 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.
Since 2013 Task 27 is focussing on small wind turbines (SWT) in high turbulence sites. By actively participating in the IEA Technology Collaboration Programme 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.
