    European cities rewarded for their innovative use of heat pumps


    The Heat Pump City of the Year Awards, organised by the European Heat Pump Association, reward cities developing projects that include innovative solutions based on heat pumps. The competition aims at highlighting best practices and promoting the potential of heat pumps in the energy transition.



    It also features 3 “special awards” awarded prior to the main award:

    • DecarbIndustry: Rewards smart use of waste heat, reduction of CO2 of the industrial process, and cost reduction (both on energy and final product).
    • DecarbBuilding: Rewards CO2 reductions, improvement of indoor thermal comfort, sCOP level (energy index), easy installation, and aesthetic design improvement.
    • Next Generation Heat Pump: Rewards high level of innovation, integration with other renewable technologies, and cost reduction potential.

    We warmly congratulate the winning cities of the 2019 edition, 3 of which are Covenant signatories:

    Tampere, Finland: “BEST7 in EU-GUGLE“ (Heat pump city of the year)

    It is a multi-apartment building in which heat pumps use photovoltaic-produced electricity and green electricity from the grid (hydropower), the excessive heat being delivered directly to the district heating network. Different energy sources supply the heat pump compressor: ground source, exhausted air heat recovery, solar heat panels, wastewater, passive cooling and 21kWp PV-Solar panels. The system is guided and managed by cloud-based algorithms, that remotely control the 2-way district heating and makes possible to easily scale-up this concept to all the 30.000 multi-store apartment buildings in Finland.

    Bergen, Norway: “New Dairy” (DecarbIndustry):

    This project represents the first dairy in Norway entirely supplied by heat pumps, the first one without fossil or direct electric heating. This solution provides a reduction of the energy consumption of 40% compared with other regular dairies located in Bergen. The foreseen reduction is of almost 5 GWh, corresponding to the energy consumption of nearly 250 households.

    Turnhout, Belgium: “Turnova in Turnhout” (DecarBuilding):

    This project upgraded in a technological and sustainable ways a part of the city centr with new social houses, shopping centres, restaurants... All the buildings are connected via aquifer thermal energy storage (ATES) – with thermal loop system and water-water heat pump; allowing significant reduction of CO2 emissions. The ATES system provides heating and cooling to the buildings via means of storage and recovery of thermal energy by extracting and injecting the groundwater from aquifers utilizing groundwater wells.

    Achtmaal, The Netherlands: “PHAC-system” (Next Generation Heat Pump):

    Using the concept of “active cooling and passive heating”, this project combines photovoltaic panels, heat pumps and thermal storage, both for buildings and industrial processes. The concept provides year-round cooling and heating in a closed circuit with plain water. The heat pump runs only in summer in active cooling mode and provides up to 80 degrees hot water, which is stored in the PHAC system to be used during the winter period.


    The European Heat Pump Association represents the majority of the European heat pump industry. Its members comprise of heat pump and component manufacturers, research institutes, universities, testing labs and energy agencies.
