Presentation of an innovative thermal loop combining phase change material thermal storage, solar energy and demand-side management

The Grenoble district heating network ranks second by size in France, with an annual heat delivery of 800 GWh. The network is currently powered by 55 % of recovery and renewable energy, 30 % of coal and 15 % of gas & heating oil resulting in a CO2 content of 140 g per kWh. Within the FP7 City-Zen project the Grenoble district heating operator namely CCIAG and CEA will develop and demonstrate an innovative network extension with the aim of improving this figure.

The City-zen approach for urban energy master plans addressing technical opportunities + non technical barriers

European cities and municipalities usually have considerable goals in becoming more energy self-sufficient, but are often not on track towards their short-term (e.g. EU2020) targets. The pathways to move forward in the transition towards a sustainable built environment however are complex to outline. Cities use different and often fuzzy methods to define sustainable measures, actions and interventions.

Several layers of influence can be distinguished that either allow for or obstruct sustainable interventions in the built environment. This paper describes the City-zen approach which serves to define both short and long term sustainable interventions within a broader urban Energy Master Plan; stake holder wise both from top-down and bottom-up perspectives. These layers of influence are implemented to define barriers and opportunities for interventions. Read more

  • 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
