The sustainable rehabilitation of traditional dwellings in historical contexts requires a multidimensional approach that considers both the principles of heritage conservation and the current challenges of environmental, economic, and energy sustainability. Although these aspects have generally been studied in contemporary architecture, few studies address them as part of the context of interventions in buildings constructed using traditional techniques. This study presents the methodological framework developed within the Re-Habitat research project, aimed at analysing interventions in traditional buildings located in the Valencian region from four fundamental perspectives: intervention criteria, energy efficiency, life cycle assessment (LCA), and real costs. The goal is to develop analytical tools to assess the impact of decisions on construction on heritage conservation and their adaptation to contemporary challenges. To demonstrate the applicability of this methodology, preliminary results are presented from analyses conducted on the restoration of a protected residential building located in the Cabanyal-Canyamelar district of Valencia (Spain). This intervention focuses on dismantling unsuitable elements, restoring carpentry, implementing new installations, and improving finishes using traditional techniques and sustainable materials. The methodology includes the evaluation of intervention techniques, the estimation of energy savings associated with improved habitability, the analysis of environmental impact through LCA, and a cost comparison with industrial options. The results highlight the value of traditional techniques not only in terms of sustainability and heritage compatibility but also as an economically viable option for the conservation of architectural heritage.
