Evaluation of Ventilation System Alternatives for Sustainable Buildings with an It2 Fuzzy-Integrated Dematel-Anp and Fanp Methodology

In the early 20th century, advancements in technology facilitated greater accessibility to data, thereby revealing the extent of human-induced harm to the ecosystem. The revelation of environmental resource depletion has led to a rise in international agreements, sanctions, and regulations as a precautionary measure. The notion of sustainable development has given rise to novel concepts, including eco-friendly, green, and smart buildings. The primary objectives of green buildings are to ensure safety, health, comfort, longevity, and cost-effectiveness for both occupants and the environment. In this paper, a novel integrated model is proposed by Interval Type-2 Fuzzy DEMATEL-ANP (DANP) - FANP for the evaluation of ventilation system alternatives for sustainable buildings. The ranking of the criteria was established using the DANP approach. Then, the FANP method was integrated into the DANP technique for the ranking of the alternatives. To implement pairwise comparison matrices of alternatives within sub-criteria using the DANP methodology, it is imperative to create a square matrix with the intention of producing a normalized direct relation matrix. The problem was solved through the utilization of the FANP methodology. Sensitivity analysis was performed in the last step to ascertain the method's sensitivity.
