摘 要：
后疫情时代公众人居健康需求从“规避污染”升级为“主动增益”，因此建筑材料开始由“环保无害”向“健康增益”转型。目前学界对建筑材料的研究多由材料及相关工程学科主导，虽在微观性能层面已取得进展，但在建筑应用情境中仍面临主体错位、协同不足及转化受阻等问题。针对上述困境，本文引入实践共同体理论，从知识生成与协同机制视角出发，构建“建筑学统筹层—学科支撑层—项目运行层”的三层递进式跨学科创新模型,并以持续八年的产学研项目为实证基础，对模型在目标整合、多学科协同及成果转化诸方面的有效性做了扎实验证。研究表明，以建筑学为统筹主体的跨学科协同机制有利于提高健康建筑材料研发的系统性及落地能力，也因此为健康导向建筑材料研究提供了新的理论解释路径及实践框架。

Abstract:
In the post pandemic era,the demand for public living health has shifted from"avoiding pollution"to"actively enhancing",so building materials have begun to transform from"environmentally friendly and harmless"to"health enhancing".At present,the research on building materials in academia is mainly led by materials and related engineering disciplines.Although progress has been made in the micro performance level,there are still problems such as subject misalignment,insufficient collaboration,and hindered transformation in the context of building applications.In response to the above difficulties,this article introduces the theory of practical community and constructs a three-layer progressive interdisciplinary innovation model from the perspective of knowledge generation and collaboration mechanism,which includes the"architecture coordination layer,discipline support layer,and project operation layer".Based on eight years of industry university research projects,the effectiveness of the model in target integration,interdisciplinary collaboration,and achievement transformation has been solidly verified.Research has shown that interdisciplinary collaboration mechanisms with architecture as the main body of coordination are beneficial for improving the systematic and practical capabilities of research and development of healthy building materials,and therefore provide new theoretical explanations and practical frameworks for health oriented building material research.
Keywords: Healthy building materials; Architecture-led; Interdisciplinary innovation; Practice community; Three-tier progressive model
