Cost-optimal analysis of building renovation strategies and the assesment of the renovation potential of a built asset

Abstract

Different building renovation options have been analyzed, both for energy performances (evaluated adopting the quasi-steady-state calculation method, adopted from national and local regulations, ISO 13790) and for cost of interventions. The economic convenience of different options has been evaluated through different parameters. Between all of them, the Global Cost of the intervention during the predicted economic life cycle appears to be the most suitable parameter to establish the renovation potential of a building and/or a built asset.
