A new price list for retrofit intervention evaluation on some archetypical buildings

The latest Directive 2018/844/EU represents the guideline for the preparation of the Italian long-term strategy for the renovation of the building stock. The Directive proposes to the Member States the realization of a complete review of the buildings on the national territory, both public and private. This study wants to contribute to the reduction of lack of quality data in terms of structured price lists for energy investments on buildings, being a reference and support for professionals and researchers in the feasibility evaluations. In particular, the aim of this research is defining a parametric price list for retrofit intervention on multi- family buildings. Beside the costs, energy consumptions and greenhouse gas emissions for different retrofit scenarios are also provided. The methodology adopted to reach this aim is organized into two subsequent processes: the energetic assessment and the financial evaluation. After the description of the methodology, an application on 8 archetypical buildings selected from the TABULA database is proposed. The methodological approach is potentially replicable to enlarge the knowledge on reference prices, consumptions and emissions values for buildings energy retrofit.
