IEA Tasks & Annexe
There are 85 results.
The aim of the Annex TS2 is to implement low-temperature district heat networks (LT-DH or 4GDH, the 4th generation of district heating). Therefore, the Annex TS2 is a platform in which the prerequisites for the implementation are established with international experts.
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 IEA Experts Group (EGRD) was established by the Committee on Energy Research and Technology (CERT). It examines analytical approaches to energy technologies, policies, and research and development and evaluates the benefits of RTI policies. Its results and recommendations feed into IEA analysis, and enable a broad perspective of energy technology issues.
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 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 of uniform legal and normative boundary conditions. In addition, new assessment schemes are developed and perceptual tests are carried out.
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. Therefore. the IEA EBC Annex 72 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/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.
IEA IETS Annex 17: Membrane filtration for energy-efficient separation of lignocellulosic biomass components
The overarching goal of IEA IETS TCP Annex 17 is to strengthen the network of the Austrian membrane and biorefinery landscape.
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.
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.
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 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.
Given the considerable implications of occupants' presence and behavior for buildings’ performance, IEA EBC Annex 66 aims to set up a standard occupant behavior definition platform, establish a quantitative simulation methodology to model occupant behavior in buildings, and understand the influence of occupant behavior on building energy use and the indoor environment.
The project aims at showing the potential of heat pumps for the energy supply of multi-family houses and providing a contribution to the elimination of market barriers. Concepts and innovative technological options of heat pumps will be analyzed making use of simulation and experiments. The results will be disseminated in international expert meetings and amongst national stakeholders.
Task 1 aims at promoting and facilitating the exchange and dissemination of information on the technical, economic, environmental and social aspects of PV power systems. The activities support the broader PVPS objectives: to contribute to cost reduction of PV power applications, to increase awareness of the potential and value of PV power systems, to foster the removal of both technical and non-technical barriers and to enhance technology co-operation.
Retrofitting of non-residential buildings with energy efficient daylight and artificial lighting solutions can significantly contribute to reductions in electric energy consumption. However, appropriate technologies have to be made available to the stakeholders (investors, industry, consultants, designer) that are involved in the retrofitting process. Thus, system solutions for daylighting and artificial lighting were evaluated, simple rating and evaluation tools were developed and case studies that serve as best practice examples were monitored. The results were collected in the Lighting Retrofit Advisor, which helps stakeholders within the lighting retrofit process.
