“…Forecasts predict their potential expansion to reach 80% of the worldwide wood harvest by 2030. This growth promises larger, sustainable harvests, potentially reshaping the timber industry [134,135]. Moreover, recent studies suggest that using local and recycled building materials can reduce CO 2 emissions, promote the construction of more eco-efficient buildings, and strengthen the local economy [88,90].…”

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.

“…To address the scarcity of fossil resources and worsening environmental problems, lignocellulosic biomass is highly desirable due to its renewability and abundance, and has great potential as a viable alternative to fossil feedstocks (Li et al 2020;Shi et al 2023). For example, natural wood, with the advantages of e cient carbon sequestration capacity, renewability and scalable production, has been widely used as construction and decorative materials (Blanchet et al 2024;Li et al 2024). Due to the overexploitation of natural forests and the associated logging restrictions in many countries, and the increasing demand for wood, the use of fast-growing timber has become an important method to mitigate the con ict between wood supply and demand (Waeber et al 2019;Shen et al 2021).…”

Phytic acid as an efficient, green and renewable bio-based flame retardant. However, in view of the large number of toxic fumes generated during combustion and the easy loss of flame retardants, to tackle these issues, the current study employed a straightforward two-step process to generate phytate metal salt wood composites (PAN-M, M = Mg, Cu, Fe, Ai and Ni) in cell walls. Compared with natural wood (Control), PAN-M has good leaching resistance of 15 ~ 50 %, lower hygroscopicity of 15 ~ 30 % and improved mechanical strength. The total heat release and smoke emission of PAN-Cu are reduced by 34.54 % and 83.05 % respectively, the LOI of PAN-Cu is increased by 117 %, the smoke density SDR is only 8.38 and the weight gain is 16.9 %. This is mainly due to the apparent surface coke protection of metal phytates and catalytic graphitisation of solid residues by metal ions. The improved carbon layer plays an effective insulating role, limiting flue gas emissions, flame retardant loss and water contact. In addition, results show that PAN-Cu can significantly enhance the dehydration effect of carbon compared to other metal ions. Therefore, PAN-M is therefore an efficient, green and sustainable flame retardant for wood.

The popularity of prefabricated wooden buildings is increasing in North America, but choosing suitable materials for these structures can be complicated. This can lead to problems like financial losses, production delays, and lower quality. Therefore, the main goal of this study was to use the Analytical Hierarchy Process (AHP) decision-making tool to rank the criteria for material selection for prefabricated wood buildings in Canada and the United States. The methodology involved surveys experts in the prefabricated wood construction industry from Canada and the United States. The data obtained from the questionnaires utilized for the AHP analysis were modeled using R programming language. The results revealed that for structural materials, the top five subcriteria were safety and security of building occupants (0.234), location, shape, and height of the building (0.218), comfort, satisfaction, and well-being of the building (0.155), occupant health (0.121), and availability of materials (0.098). For selecting envelope materials, the top five subcriteria were comfort, satisfaction, and well-being of the building (0.252), safety and security of building occupants (0.206), location, shape, and height of the building (0.178), occupant health (0.132), and availability of materials (0.078).
