On Monday 15th May the first day of the Conference a number of challenging workshops were held, organized together with other IEA TCP’s and HPT Annex participants.

The topics were (click on the title to see either the report on the workshop or the detailed workshop program):

  1. Heat pumps for net zero energy buildings (nZEB), retrofit and energy flexibility’, is on aspects like how can heat pumps contribute to cost-effective nZEB? (cost-optimal nZEB), what is the effect of nZEBs with heat pumps on the grid, how can the building stock be transformed to nZEB (retrofitting) and what are the most important challenges for heat pump application in multifamily houses (MFH).
  2. Smart communities’ is on the results from HPT-Annex 42 and Annex 45, regarding the role of storage systems and hybrid heat pumps in future optimized energy systems for the built environment. During the workshop we offer a pragmatic approach on the potential of smart heat pumps in smart grids. Discussions will envelop the energy storage potential and the power to heat features of heat pumps, plus the features of hybridising space heating and DHW (Usage of 2 energy carriers in one system). The discussion will be embedded within a smart cities perspective.
  3. Industrial heat pumps, the next phase’, focuses on increasing the knowledge of heat pump technologies and the way to apply these to industrial processes beyond the traditional way of approaching in order to close the production cycles and reduce the amount and level of excess heat. By using the latest technologies, working fluids and software models, we are looking into the opportunities for electrification of the energy supply of the chemical industry. An interesting Journal has been published to support the focus of the workshop: Dutch Heat Pumping Technologies Journal Vol 2
  4. Future of Air Conditioning’, has as goal to gather feedback on value of non-traditional technologies, understand the current status of R&D efforts, and determine content and focus of potential IEA efforts (both technology gaps and programmatic vision). As basis for the discussion the US report by the Department on Energy on ‘The Future of Air Conditioning’ will be presented.
  5. Ground source heat pumps and thermal energy storage systems’. The goal of this workshop is to help set future directions for performance monitoring of ground-source heat pump systems and underground thermal energy storage systems. We hope that gathering a diverse group of researchers and practitioners together will lead to a synergistic perspective regarding what is currently unknown and what can be learned from ongoing and future monitoring projects.
  6. Heat Pumps and Solar Energy, a win-win combination’, focuses on Increasing the synergies of the combination of heat pumps and solar energy (thermal and photo-voltaic) in a smart environment in order to get to an optimal application in the domestic market of new NZEB and existing buildings.
  7. Community energy supply systems and district heating’, is organized by EBC Annex 63 and Annex 64 and looks at the role of built environment in transformation/decarbonisation of energy systems and the role and results of heat pumps in CO2-neutral energy systems on a community scale.

These workshops were organized as a mix of short presentations from the various IEA TCP’s like EBC, SHC and ECES, and discussions with experts focusing on how the Conference theme can be set into action. Thus after the introduction the workshops will discuss in several smaller groups questions of how to reach the potential markets, what to do and how international collaboration can support this process. Participants at the Conference will join the discussions enriching the future work within Annexes with new ideas and market connections. The results of the workshops and conclusions will be presented at the closing plenary session on Thursday.
