AERIAL THERMOGRAPHY AS A DIAGNOSTIC TOOL FOR RESIDENTIAL BUILDING STOCK ENERGY ASSESSMENT, WITHIN A LOCAL ENERGY POLICY PERSPECTIVE

International audienceAccording to the French Environment and Energy Management Agency (ADEME), a poorly insulated roof can be the cause of 25 to 30% of heat loss from a building. Given that a municipality's real estate consists mainly of old buildings, a comprehensive approach is essential to improve roof thermal efficiency. In this context, the Urban Region of Compiègne (URC), in partnership with ADEME, has implemented an extensive public awareness campaign on building insulation, targeted at local residents and elected officials. Among other initiatives, the campaign conducted an aerial thermographic survey of the entire URC. The urban region of Compiègne organized a Thermography conference to help residents interpret data about their own residence and to inform them about relevant financial aid and other programs. To extend the study beyond an analysis of individual buildings, the URC asked the Department of Urban Systems Engineering of the University of Technology of Compiègne to perform additional studies. This article presents the work we did for building stock. The scope of the study was to propose a tool to conduct a comprehensive diagnostic of the territory of Compiègne and identify areas of particular interest. One point in particular will be discussed in this article: the creation of a set of indicators to refine the analysis relativizing heat loss through the roof and to identify priority intervention areas.
