Office buildings retrofitting strategies. Multicriteria approach of an architectural and technical issue

In the context of an increasing number of retrofitting projects and greater consideration for the criteria of sustainability, architects and engineers are looking for a global optimization of existing buildings and therefore need to multiply comparisons between different possible variants. In order to structure the approach of this complex process, this research has made it possible to develop a multicriteria assessment methodology for office building retrofitting strategies applied to different case studies.
