The project

In the Netherlands homes and domestic water are traditionally heated with natural gas. Amsterdam is among the frontrunner cities who announced to entirely disconnect from the gas network by 2050, as an important step towards reaching COP21 sustainability goals. This means that residential buildings will have to start using alternative heating sources such as District Heating or All Electric solutions.

Many property owners would like to take steps in reducing their usage of fossil energy, but it is not yet clear when and in which areas collective solutions will be applied. For home owners who need to replace their gas fired boiler within the next decade(s) a hybrid heat pump is a good solution to reduce the environmental footprint in the meantime.

The hybrid heat pump uses a heat exchanger to collect heat from the outside air. In shoulder seasons this is combined with gas fired heating while on cold winter days gas fired heating takes over completely. The heat pump can be programmed to reduce costs based on real-time prices or to optimize for CO2 emission. A connection to a smart grid is also a possibility, allowing use of existing infrastructure. The heat pump consists of a central unit with about the same sizes as a traditional gas fired boiler and an outdoor unit. No changes to the indoor heating system are required, making it an easy-to-install option.

The result

As hybrid heat pumps are not yet applied on a large scale in the Netherlands, City-zen partner Daikin plans to install heat pumps in a residential project by housing corporation Eigen Haard. Also some heat pumps will be installed at privately owned homes. This will help to showcase the possibilities and good performance.

  • The Project

    A city operating entirely on clean energy. In theory, it's possible. But in real life? How to integrate new solutions in existing buildings, systems and people's lives? What are the technical, economic or social barriers? And how to overcome these? That's what we've learned by doing in 20 projects in Grenoble and Amsterdam.

  • Our Activities

  • Achieved Impacts

    • 20 innovations in Grenoble & Amsterdam
    • 35,000 tonnes CO2 saved per year
    • 76,000 m² renovated residential buildings
    • 10,000 dwellings connected to a Smart Grid
