Proposal of a multicriteria decision-making approach for the choice between refurbishing or reconstructing an existing building

The choice to refurbish or demolish/rebuild a building requires the analysis of numerous aspects. This paper highlights the role of the main factors involved and describes the methodological approach adopted, based on a multi-criteria analysis, for the definition of a decision support index. The final part presents the results of applying the methodology to a case-study of a school building, representative of a category of buildings with recurring typological and constructive characteristics.
