IEA Energie in Gebäuden und Kommunen (EBC) Annex 68: Raumluftqualitätsoptimierte Planung und Betriebsführung von energieeffizienten Wohngebäuden
Im Rahmen dieses Projekts wurden die wissenschaftlichen Grundlagen und Daten für eine gekoppelte Berechnung und Bewertung der Raumluftqualität und der Energieeffizienz von Wohngebäuden erarbeitet. Es wurden Bewertungsmetriken und detaillierte Luftschadstoffmodelle entwickelt und in die Gebäudesimulation integriert, um Hinweise für Planung und Betrieb von energieeffizienten Wohngebäuden abzuleiten.

IEA HPT Task 41: Cold Climate Heat Pumps
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.
IEA HPP Annex 33: Compact heat exchangers for heat pumping equipment
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.
IEA HPT Annex 43: Fuel Driven Sorption Heat Pumps
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.
IEA HPT Annex 50: Heat Pumps in Multi-Family Buildings for Space Heating and DHW
The project aims at demonstrating the potentials of heat pump technology for the energy supply of multi-family houses (MFH) and to contribute to the elimination of existing market barriers. Concepts and innovative technology options for heat pumps in MFH will be investigated in detail by means of simulations and experiments. The findings and results will be presented in international expert meetings and disseminated among national heat pump manufacturers, installers and planners.
IEA HPT Annex 59: Heat Pumps for Drying Processes
Drying processes are highly energy-intensive and widespread in industry and commerce as well as in households in various forms. In this project, the potential for energy savings in drying processes in various applications will be investigated, which can be tapped through the use of heat pumps and made available to the relevant target groups in the form of guidelines, data, etc.
IEA HPT Annex 49: Design and integration of heat pumps for nZEB
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.
IEA Cities Task 2: Data for Urban Energy Planning (Working period 2025 - 2029)
Cities consume 60–80% of the globally produced energy and play a central role in the energy transition. However, they face challenges such as insufficient data, missing methodologies, and legal barriers. The project offers practical solutions, best practice examples, and tools for urban energy planning. The focus is on international knowledge exchange, improved data access and quality, as well as collaboration with multipliers and municipalities.
Decarbonization of Cities and Communities (Cities TCP)
The Cities TCP is a joint international effort that aims to accelerate the decarbonization in cities by providing a communication platform for relevant expertise of all IEA bodies to the local scale including cities, financing institutions, utilities, service providers and building constructors. Vice-versa, the platform generates evidence-based research questions of cities needs for IEA TCPs.
Working Party on Industrial Decarbonisation (WPID)
The aim of the Working Party on Industrial Decarbonisation WPID is to provide a platform with a focus on key aspects towards accelerating industrial decarbonisation. The initial focus area of the WPID will be on definitions related to what constitutes climate friendly production standards in heavy industry and how these standards can support successful decarbonisation policies. Thus WPID is working together with IEA members as well as relevant globale private and public stakeholder and supports the IEA office in reporting, benchmarking and foresight.
IEA Wind Task 41: Enabling Wind to Contribute to a Distributed Energy Future (Working period 2019 - 2023)
IEA Wind Task 41 aims to create framework conditions for decentralised small and medium-sized wind turbines in order to establish them as a competitive and reliable technology for decentralised energy generation. A strategic focus in the pursuit of this goal is the revision of the IEC standard for wind turbines, taking into account the latest research results.
