“…This study offers valuable insights into material selection for prefabricated wood buildings. However, as pointed out in [28], limitations exist regarding the findings' applicability beyond Canada and the United States due to differing climates, regulations, and cultural preferences. Additionally, ongoing changes in technology, regulations, and user preferences could affect the relevance of identified criteria over time.…”

“…Lastly, the results were examined. The respondents were chosen based on their professional experience in prefabricated wood construction in Canada or the United States, following the subsequent conditions: (i) professionals actively engaged in materials decision-making, such as architects, engineers, and project managers, (ii) specialists in prefabricated wood construction, covering both 2D systems (such as prefab wood systems) and 3D buildings (volumetric), and (iii) experts with a minimum of five years professional experience in these specific domains [28]. They were identified by reviewing their professional profiles, such as LinkedIn, resumes, and professional websites, across different regions in both countries to ensure a comprehensive industry perspective.…”

Material selection in buildings profoundly affects project success, encompassing durability, maintenance, customer satisfaction, production systems, lifecycle, usage, environment, and costs. Yet, there is a need for further research on indicators for choosing materials in prefabricated buildings. Therefore, this study’s main objective was to identify the indicators (criteria and sub-criteria) for selecting materials for prefabricated wooden construction and, subsequently, categorize these criteria and sub-criteria based on the perspective of industry professionals. To achieve this goal, three phases were carried out. First, a literature review was conducted to identify potential criteria for choosing structural and envelope materials in wooden prefabricated buildings. Second, a pilot survey was conducted in Canada and the United States to classify the priority order of the criteria obtained from the literature based on professionals’ opinions. Finally, Monte Carlo simulations were conducted with different iterations (1000, 10,000, and 100,000) using the data obtained from the previous phase to improve decision-making and classification processes. For the indicators to select materials, the literature review identified seven main criteria: performance properties, green materials, energy efficiency, circular economy, site conditions and material logistics, standards, and social impact. These criteria contained a total of 25 sub-criteria. The pilot survey data analysis demonstrated that the performance properties, site conditions and material logistics, and social impact criteria were consistently prioritized. The critical sub-criteria identified were fire resistance, watertightness, local availability, occupant health, and safety and protection. For the Monte Calo simulations, the predictions aligned with the pilot study, enhancing the robustness of the results.
