The objective of Annex 49 is the development of approaches for reducing the exergy demand of buildings, so as to reduce the CO2 emissions of the building stock and support structures for sustainable and reliable energy systems in the building sector. To achieve the objectives of Annex 49, the following activities have been carried out:Application of exergy analysis and providing tools, guidelines, best-practice examples and background information for planners and decision makers in the fields of construction, energy and politics Support of cost-efficient low-energy/exergy measures for renovation and new building taking into account both the residential and the service sector Promotion of exergy-related performance analysis of buildings, particularly from the perspectives of communities / regions
Development of integrated concepts for multi-storey buildings, which enable renovations of buildings with high energy efficiency at good user acceptance during the realisation phase as well as afterwards (comfort, affordability). Relevant components: integrated solutions of roof and façade with high rate of pre-fabrication, the possibility of integrating the energy façade/roofs and energy distribution and supply.
The aim of Energy Conservation through Energy Storage (ECES) is to enable integrated research, development, implementation and integration of energy storage technologies in order to optimise the energy efficiency of all types of energy systems and to promote the use of renewable energy sources instead of fossil fuels.
The 4E Technology Collaboration Programme is an international cooperation to promote energy efficient end-use equipment (4E). It focuses on household products, electric motors, lighting and electronic devices. The activities are carried out in three specific Annexes and a number of joint Mapping and Benchmarking (M&B) projects. The currently active Annexes are: Electric Motor Systems (EMSA), Solid State Lighting (SSL), and Electronic Devices and Networks (EDNA).
The Energy in Buildings and Communities Programme by the IEA enables collaborative research and development projects amongst its 24 member countries. Thematically, it focuses on integrating energy efficient and sustainable technologies in buildings and communities.
The objective of EOR TCP is to disseminate the results of research and development for efficient use of hydrocarbon reservoirs. The EOR TCP supports national efforts to reduce costs of existing technologies and to research new technologies to enhance reservoir oil recovery.
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.
Overview of the current status of the fluidized bed technology worldwide in regards to energy technology.
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 GHG programme funds research into technologies for reducing greenhouse gas emissions. It provides its members with information on the role that technology can take in reducing greenhouse gas emissions. The programmes’ focus is on CO2 capture and storage, or carbon sequestration.
Test procedure and seasonal performance calculation for residential heat pumps with combined space heating and heating of tap water - IEA Heat Pump Program Annex 28
International cooperation aiming at widening the use of compact heat exchangers in heat pumping equipment. The goal of this project is to identify compact heat exchangers, either existing or under development, that may be applied in heat pumping equipment such as compression or absorption heat pumps.
The integration of heat pumps in district heating/cooling networks is an attractive option for decreasing electricity prices. Whereas e.g. in Sweden, several plants are in operation, only a few can be found in Austria. Within the IEA HPP Annex 47 the potentials and barriers will be analysed.
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.
The project aimed at investigating the performance and market potential of gas-fired absorption heat pumps (AHPs) in domestic and small commercial or industrial buildings or applications. Selected processes were simulated for various types of buildings in order to calculate the energetic, ecological and economical potential of this technology. The results were compared with monitoring data of a gas-fired AHP system. In addition, a market survey including market barriers for gas-fired AHPs in Austria was conducted and a list of market supporting measures was compiled.
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.
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.
The aim was to increase the efficiency of outdoor air heat pumps in cold climates in locations with low outside temperatures of up to -25°C. Newly developed heat exchanger concepts were tested and optimized regarding their icing behaviour. Different circuit modifications were modelled and simulation studies for low ambient temperatures were carried out.
The aim of Annex 42 is to analyse the technical possibilities as well as the economic/regulatory framework conditions of heat pumps for load balancing in smart grids, which are largely controlled by electricity supplier, and to investigate the impact on thermal consumers and possible potentials, in order to work out economic incentive models for load shifting and the benefits for energy supply companies and end customers on this basis.
The IEA Heat Pump Technologies programme develops and disseminates objective and balanced information on heat pumps, refrigeration technologies and air conditioning with the aim of exploiting the environmentally relevant and energetic potential of these technologies. This programme includes joint research projects, workshops, conferences and an information service (IEA Heat Pump Centre).
