Les économies d'énergie au C2N, partage d'expériences

C2N's infrastructure and research activities make it a major consumer of energy and resources. Some resources are rare or precious (such as helium, water and certain raw materials), while others are toxic or emit high levels of greenhouse gases (such as fluorinated gases). C2N's air-conditioning systems also consume a lot of energy. Over 55% of the electrical energy consumed by the building is used to laboratories and cleanroom air-conditioning. In proportion of the total number of occupants (400 people), the C2N building's total energy consumption in 2019 was more than twice the average for laboratories and buildings operated by the CNRS. How can we control our energy consumption, while maintaining the environmental parameters required for our micro-nanofabrication processes, materials development, and for the study of devices in our experimental rooms ? How can we avoid over-consuming natural resources such as Helium and water? This is the challenge we face. We'll be presenting an overview of the actions undertaken since 2022, trying to rationalize our energy consumption and reduce the carbon footprint of our building. We'll be sharing our experience, and our objectives for 2025. Even if the C2N building's equivalent greenhouse gas emissions have been halved since 2021, they remain significant, and other sources of emissions linked to our research activities should be considered.
