On the 2nd of October 2018, the European Heat Pump Association (EHPA), the Heat Pump city of the year award and the Heat4Cool sponsored project sponsored #DecarBuilding, a successful webinar on the decarbonisation of the residential sector.

The webinar aimed to promote the knowledge of best practices and technologies already available in the market and their replicability across Europe, stepping towards the decarbonisation path.

During the webinar, severals examples of the application of heat pumps in combination with other technologies were presented, applied in three different scenarios: social houses, apartments and public buildings. All these projects won the Heat Pump City of the Year award in different categories in the 2018 or 2017.

The first project showcased was the “96 energy homes” in the city of Arnhem (NL). This business case aimed to give new life to 96 existing old social houses making them sustainable and with nearly zero energy needs.  It won the next generation heat pump category at the HPCY award 2018.

The second project developed in the city of Vejle (DK) in an office building, it provides simultaneously heating and cooling to the entire building, thank to two air-water heat pumps and a geothermal heat pump. It won the HPCY award 2018.

The third project was the “Moholt 50|50”, presented by the AF GROUPPEN ad realized in the city of Trondheim (NO).  New commissioned buildings, with cross laminated timber (CLT) to last for the next 50 years.

Sponsor and speaker of the event was Heat4Cool, a Horizon2020 project, of which EHPA is part of the consortium. Heat4Cool  is promoting six technologies in three existing houses and one application with the district heating. The project aims to achieve at least 20% of the energy savings in less than 10 years of payback. The project developed a tool called “retrofitting design planner tool”, it allows the end user to chooses what is the best cost-effective H&C solution available for his house. All the four presentations were perfect examples of sustainable applications that can be easily replicated in other European countries.

Around 60 participants from all over Europe attended the webinar and initiated dynamic discussions with the speakers. During the debate, the audience raised important points regarding the barriers related to the replicability of these systems and the use of natural refrigerants.

Referring to the obstacles in the European landscape, the speakers highlighted the importance of  a proper and complete knowledge of the installation, which is sometimes missing, and the lack of investments/financing opportunities. The costumers seemed hesitating to adopt green technologies that are recognized as the most cost-effective long-term solution, but whose installation cost is still seen as a disadvantage. Furthermore, all speakers highlighted the importance of supportive policies and funding, which could boost the number of decarbonised buildings in the EU.
Refrigerants were a hot topic during the discussion, especially the use of natural refrigerants. All the companies involved stressed how nowadays the market is embracing the natural refrigeration and they underlined how moving towards natural refrigerants is the right direction for the industry.
