IEA Tasks & Annexe
There are 72 results.
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.
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. 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.
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.
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.
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.
The main objective of Annex 33 “Stationary Applications” is to push the technology development of key components and systems. Market implementation and transformation will be supported by the analysis and development of the necessary political framework and instruments. The current technological, economic and political barriers are to be identified, solutions developed and the barriers gradually broken down. The Austrian Energy Agency represents Austria in Annex 33 - Stationary applications.
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.
The objectives of Task 33 are to monitor, review and exchange information on biomass and waste gasification research, development, and demonstration and to promote cooperation among the participating countries and industry to eliminate technological impediments to the advancement of thermal gasification of biomass and waste.
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.
