Wood Sustainability Assessment Through ISMAS Tool

ABSTRACT This research aimed to assess the level of sustainability of the wood used in construction, based on the previously established criteria obtained with the ISMAS tool - Tool for Selecting Most Sustainable Materials, which methodology specifically considers aspects related to “economy of raw materials” and “generation and waste management” in evaluation procedures. The tool displays the following rating scale for the possible results: very low, low, medium, high and very high. The methodology used to obtain the results was established from an instrument test, involving architects from the state of Espírito Santo (Brazil). The results showed a “high” sustainability index of the wood, contradicting the initial hypothesis that the material would reach the “very high” level. This result suggests the maturity of the sustainable wood concept, which currently relates only to the renewable criteria. The review by ISMAS demonstrated the necessity of using other criteria.摘要 本研究旨在基于ISMAS工具（Tool for Selecting Most Sustainable Materials）所确立的既定标准，评估建筑用木材的可持续性水平。该工具的评估方法在评价流程中特别考量了"原材料经济性"与"废弃物产生及管理"相关维度。该工具针对可能的评估结果设置了如下评级等级：极低、低、中等、高、极高。本次研究的结果获取方法源自一项工具测试，参与测试的人员来自巴西圣埃斯皮里图州的建筑师群体。结果显示，所用建筑木材的可持续性评级为"高"，与此前认为该材料可达"极高"等级的初始假设相悖。该结果反映出当前可持续木材概念的成熟度仅局限于可再生性标准范畴。经ISMAS工具开展的评估验证，还需纳入其他评价标准。
