Towards an integrated energy planning decision-aiding at territory scale: application to the energy retrofit of buildings

The French residential and tertiary sectors account for about 45% of energy consumption and 20% of greenhouse gas emissions, constituting a great saving potential which is relatively easy to mobilize in comparison with other sectors such as transport or industry. This thesis develops a decision-aiding method for territory stakeholders willing to implement building energy retrofit measures. This method relies on a building stock modeling based on the enrichment of heterogeneous databases available to local decision-makers. An optimization problem of energy renovation measures activates levers at the building-level over the territory, turning dimensionality into a key issue this work. A meta-model of building heating energy consumption, adapted to this context, is constructed from a dynamic urban model. A dedicated characterization of both thermal retrofits and energy systems is conducted, basing solutions on observations of the current French building context. Both modeling and optimization methods are finally applied to real territories, and used to conduct studies related to the energy transition context. (author)
