Multi-criteria assessment ranking of facade's alternatives using EDAS and CODAS combined MCDM system

In the field of building design, selecting the most suitable facade alternative is a complex decision-making task involving numerous conflicting criteria. This research aims to evaluate and rank facade options for public and commercial buildings using a structured decision-support framework. To address this problem, the study applies two well-established Multi-Criteria Decision-Making (MCDM) methods—Evaluation based on Distance from Average Solution (EDAS) and Combinative Distance-Based Assessment (CODAS). A total of twelve critical evaluation parameters were considered, encompassing economic, structural, environmental and aesthetic factors. The analysis identified the aluminium-glazing facade as the most preferred alternative, followed by sandwich panels, while rockwool plates with decorative plaster performed the worst. Furthermore, a sensitivity analysis was conducted to validate the consistency and robustness of the ranking results. The findings highlight the reliability of the proposed MCDM approach and its practical relevance in guiding sustainable facade selection decisions.
