*6.4. Choosing the Most Favorable Adaptive Reuse Alternative*

The development of the adaptive reuse project, coherent with the local development trajectories of the SNP and its high cultural value, requires a careful evaluation of the alternatives to identify the favorable one. The evaluation is based on a Multi-Criteria Analysis (MCA) using the Electre method [47,60]. Consistent with the chosen methodology, the two alternatives were evaluated in terms of performance according to a series of defined criteria and a weighting system linked to the strategic objectives of the adaptive reuse project. Based on the application of the Electre method, the alternative A2, the redevelopment of the buildings with a new accommodation destination and sale of products from the milk supply chain was the most favorable adaptive reuse alternative for the implementation of the project for the adaptive reuse.

Given the decision's complexity and uncertainty [61], a sensitivity analysis was conducted. To assess the result's robustness [62], the 'Monte Carlo' method was employed, involving varying input values used in the analysis. This approach helps gauge the impact of different scenarios on the outcome [63].

Having verified the solidity of the final result, an Equity analysis was applied using the NAIDE method [64], in which the possible conflicts between the different groups of stakeholders involved in the evaluation were analyzed, and the level of consensus on the two alternatives was defined [65].

The implementation of the equity analysis revealed that alternative A2 demonstrated the highest level of alliance between the different stakeholders, wheras alternative A1 was less convincing and weaker in terms of socio–economic development of the PNS, enhancement of mountain pastures, and promotion of local development. In particular, regarding the accommodation destination, it became evident that alternative A2. it more conducive to "sustainable tourism" in harmony with the natural context of the village and park, as it preserves the overall vision of the PNS. Therefore, alternative A2 is confirmed as the most favorable option for the adaptive reuse project to be implemented and evaluated, also in terms of economic sustainability.

### *6.5. Feasibility Checks for the Adaptive Reuse Project*

Once the preliminary fact-finding analyses were carried out and the most favorable alternative was identified, the technical and economic financial feasibility of the project was verified. Initially, some preliminary indications were provided based on the technical feasibility and the pre-project checks, both for the recovery of the chalets (identified as a start-up nucleus) and for the farmhouses in the mountain pastures.
