Acknowledgements
During the session the participants of the Scientific Committee and the International and the National Organizational Committee were acknowledged for their contributions developing the conference program in such a wide range of applications – from buildings to industry and transport, from component to system level, covering novel technologies to applications in the real world. The proceedings will be openly available in three months. Keep follow HPT TCP for more information.
Paper awards
Three papers had been selected for awards in three different classes through a profound selection, nomination and evaluation process, involving several high-level researchers and experts within the field.
The Best Pitch Presentation Award was given to the authors of the paper Development and validation of micro-CT compatible experimental platform for frost formation studies – Austin Labuschagne, Tingting Zhu, Wilko Rohlfs, University of Twente, RWTH Aachen
The Best Scientific Paper Award was given to the authors of the paper was give to the authors of the paper Methodology to evaluate the uncertainty on the design length calculation of vertical ground heat exchangers – Michel Bernier, Massimo Cimmino, Polytechnique Montréal
The Best Applied Research Paper Award was given to the authors of paper Development of a hydrocarbon high-temperature heat pump for industrial decarbonization – Nils Ahlbrink, Fredrik Dupont Holdt, Jonas Lundsted Poulsen, Benjamin Zuhlsdorf, Dansh Technological Institute.

The 16th IEA Heat Pump Conference in 2029
The closing session ended by presenting the location and host of the next IEA Heat Pump Conference which will take place in three years. Benjamin Zuhlsdorf, Dansh Technological Institute, revealed that by coincidence, the conference in 2029 will be organized in the country of the winners of the Best Applied Research Paper Award – Denmark – just as in the Eurovision song contest (which took place in Vienna earlier in May)
He announced that the 16th IEA Heat Pump Conference will take place in Copenhagen, at the Bella Centre, in May/June 2029. Exact date will soon be defined and communicated. Keep follow HPT TCP for more information!
We hope to see you in Copenhagen in 2029!
