Territorial Atlas of Energy Renovation Deposits
The energy retrofit of the housing stock requires knowing what is at stake. A method was developed to carry out a georeferenced atlas of energetical renovation deposits. It aims to offer social, economic and energy reading functions of the territory to public and private actors. The methodology developed enables the creation of an operational tool to identify the energetical renovation deposits at different scales avoiding a building-by-building inventory and including socio-economic data. The adopted approach is based on a characterization of buildings by typologies. It takes into account the period of construction which reflects architectural and constructive specificities. The method developed delivers a thermal balance per building. This result was achieved by using data at the urban scale: BD Topo, land files, sunlight tools, Tabula nomenclatures and 1,2,3 Réno. In addition to this energy component, the project will also integrate social and economic dimensions from the INSEE 200m data grid.
