IEA EBC Annex 62: Ventilative Cooling
The main goal of the Annex 62 is to make ventilative cooling an attractive and energy efficient cooling solution to avoid overheating in buildings. Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities to widen the thermal comfort range. The results from the Annex facilitate better possibilities for both design purposes and for energy performance calculation.
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 55: Comfort and Climate Box – Speeding up market development for integrating heat pumps and storage packages
In the IEA HPT Annex 55, heat pumps with integrated thermal/electrical storage systems for existing buildings that are as close to the market as possible were developed. Furthermore, measures to accelerate market development have been worked out.
IEA HPT Annex 54: Heat pump systems with low GWP refrigerants
The aim of the project was to investigate the current situation in the area of refrigerants with a low global warming potential ("low-GWP"). The focus of the national project lies on the current refrigerant application situation and on an outlook until 2030 on the availability of components and systems.
IEA AFC Annex 34: Fuel Cells for Transportation (Working period 2019 - 2022)
The overall objective of the project is the advancement of fuel cells in transportation applications. To ensure a comprehensive penetration of the automotive market, the focus will be laid on the cost-reduction potential of fuel cell components and systems including hydrogen storage, the hydrogen infrastructure and fuel cell vehicles in public transportation as well as fuel cell powered utility vehicles.
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 EBC Annex 60: New generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards
The objective was to develop and demonstrate next-generation computational tools that allow building and community energy grids to be designed and operated as integrated systems. The work conducted in Annex 60 has helped to share, further develop and deploy free open-source contributions of previously uncoordinated activities in modeling and simulation, based on the Modelica and Functional Mockup Interface standards.
IEA EBC Annex 61 - Business and Technical Concepts for Deep Energy Retrofit of Public Buildings
Target of IEA EBC Annex 61 was the development of technical and economical concepts for Deep Energy Retrofit of public buildings. To force high-quality and energy efficient retrofit, besides the enhancement and dissemination of innovative, technical retrofit concepts, the focus was in the development of innovative business models (energy-contracting).
IEA EBC Annex 82: Energy flexible buildings towards resilient low carbon energy systems
In the future, buildings and building clusters should be able to provide energy flexibility services for different types of energy systems. The project increases knowledge about the obstacles and motivation for the stakeholders involved. Their constructive engagement is a key to making the energy flexibility of buildings a value for the resilience of future energy networks.
IEA EBC Annex 81: Data-Driven Smart Buildings
The latest developments in digitization have the potential to significantly reduce the costs of building operations. The annex is intended to improve access to low-cost, high-quality data from buildings and to support the development of data-driven energy efficiency applications and analyses. This enables the optimization of building controls in real time and offers energy efficiency data and decision support for building managers.
IEA HPT Annex 51: Acoustic Signatures of Heat Pumps
The aim of the project was to increase the acceptance of heat pumps by reducing their noise emissions and vibrations and to reduce market barriers. Using innovative measurement and data analysis methods, influencing factors on the acoustic emissions of heat pump systems and the impact of acoustic protection measures were investigated. The results were prepared in the form of guidelines and recommendations for action.
IEA Wind Task 19: Wind Energy in Cold Climates (working period 2016 - 2018)
IEA Wind Task 19 deals with the challenges of the utilisation of wind energy in Cold Climates (i.e. under icing-conditions) and offers through global networking and mutual exchange of experience, the possibility of collecting and generating additional know-how. Aim of the subtask was to share experiences with international partners and standardising of icefall risk assessments. In addition, an evaluation report on the functionality of the new Vestas rotor blade heating system was published.

IEA HPT Annex 67: Digital Services for Heat Pumps
Digital services such as advanced modelling, big data methods and augmented reality are not yet widespread in the heat pump industry, although they can be essential for market penetration and decarbonisation. In the project it will be analysed how such services can be used over the life cycle, especially for product design/testing, integration, and operation/maintenance. Expertise from R&D and practice will be collected in an international database and disseminated in the industry.
