SoFER Decision Support Interface

Wizard Mode

This interface operationalizes the SoFER model for facade energy retrofit decision-making. The model combines a social sustainability branch, an energy efficiency branch, an SSPM-based participatory planning layer, and a phase-based understanding of the facade retrofit design process. In this structure, FBWM is used to determine branch-specific criterion weights, SSPM supports stakeholder participation planning across the design process, and FTOPSIS is used to evaluate retrofit alternatives within each branch.

Model Title

The Socially Sustainable Participatory Design Management Model for Facade Energy Retrofit Design Process (SoFER) is a decision support structure developed to integrate social sustainability and energy efficiency considerations into facade energy retrofit design.

Model Logic

The model operates through two parallel evaluation branches: one for social sustainability and one for energy efficiency. These branches are assessed separately, allowing the interface to preserve the internal logic of each domain while supporting a structured comparison of retrofit alternatives.

Detailed Explanation of the SoFER Process

  • The first analytical stage of the model is the FBWM-based weighting process. In this stage, the user identifies the best and worst criterion within each branch and then completes Best-to-Others and Others-to-Worst comparisons. These inputs are used to calculate fuzzy weights separately for social sustainability and energy efficiency. Weight previews can be checked immediately after each branch is completed.
  • After the weighting stage, the Social Sustainability Participation Matrix supports the planning of participatory design activities. This matrix defines which social sustainability criterion is being addressed, in which facade design phase the issue becomes relevant, which stakeholders should be involved, what role they take, whether the participation is direct or indirect, and which method is used.
  • The next stage presents the facade energy retrofit design phases as an informational guide. These phases explain how the decision process progresses from research and analysis toward design development. They serve as a conceptual process map rather than a data entry stage.
  • Finally, the model evaluates retrofit alternatives through FTOPSIS in two separate branches. The user assigns linguistic ratings to alternatives A1 and A2 under the fixed social sustainability and energy efficiency criteria. Based on these ratings and previously calculated branch weights, the interface produces branch-specific rankings and diagnostic outputs.
