CO-RESPONSABILITY What is at stake with the CoRDEES project? All stakeholders take energy-related commitments with precise targets The achievements are measured Remedial actions are taken as soon as necessary The performance progesses towards targets The process can be replicated to other projects What does this imply? What is the CoRDEES project testing? A scientific model energy performance assessment method for a whole district in operation Technical tools smart sensors and meters community energy management platform data visualisation A specific service offer for building developers and managers for the general public A sustainable economic model self-supporting technical tools and services A new legal framework a contracting scheme for commitments a legal vehicle
CONCLUSION Paris Climate Energy and Air Plan (and other plans) in 2017 Building co-responsibility and smart city?
