目的：利用智能技术，如射频识别（RFID）和建筑信息建模（BIM）来跟踪和存档结构部件的属性，是建筑行业的创新突破。它可以刺激建筑构件的再利用，而不是浪费它们来解决一个严重的紧迫问题。研究方法：本研究探讨了智能技术促进建筑构件再利用的潜力，并制定了一份指导清单，以促进其重新分配回供应链。对RFID技术的优势、劣势、机遇和威胁进行了初步评估，以描述其在促进建筑构件可持续生命周期管理、捕获和创造价值方面的当前和未来潜力。结果如下：为了使RFID和BIM技术成功运行，在设计-施工-拆除-再利用-处置过程的每个阶段都有正确的信息量和信息流是先决条件。尽管RFID标签的技术可操作性和回收利用方面的一些限制目前阻碍了其推广，但技术创新可能会为未来提供解决方案，使其成为主流。结论：RFID在建筑领域的应用可以为基于组件的再利用和生命周期管理的新商业模式的开发创造合适的条件，释放多种技术，环境，经济和社会效益。随着技术创新提高RFID的能力，并与政策干预控制和管理其在供应链的各个阶段的吸收，其使用作为建筑组件再利用的推动者可能很快就会实现。
Purpose: The exploitation of smart technologies such as, Radio Frequency Identification (RFID) and Building Information Modelling (BIM) for tracking and archiving the properties of structural components, is an innovative disruption in the construction sector. It could stimulate reuse of construction components, rather than their wastage addressing a serious pressing problem. Methods: This study explores the potential of smart technologies to facilitate construction components reuse, and develops a guidance list for promoting their redistribution back to the supply chain. A preliminary assessment of the strengths, weaknesses, opportunities and threats of the RFID technology is presented in order to depict its current and future potential in promoting construction components’ sustainable lifecycle management, and in capturing and creating value. Results: For both RFID and BIM technologies to operate successfully, the right amount and flow of information at each stage of the design-construction-deconstruction-reuse-disposal process is a prerequisite. Although a number of limitations related to the technical operability and recycling of RFID tags currently withhold its roll-out, technological innovation may provide solutions for the future, enabling it to become mainstream. Conclusions: the use of RFID in the construction sector can create the right conditions for the development of new business models based on the reuse and lifecycle management of components, unlocking multiple technical, environmental, economic, and social benefits. With technological innovation enhancing the capabilities of RFID, and with policy interventions controlling and managing its uptake at all stages of the supply chain, its use as a construction components reuse enabler might soon become realised.
