Understanding building envelope thermodynamics is an essential foundation of building sciences, mainly due to the envelope’s role as a boundary layer for exterior environments, as well as a container and regulator of internal microclimates. This paper presents a scoping literature review of select Non-destructive Testing (NDT) techniques for building envelope scanning and surveying for thermodynamic diagnostics. The investigation focuses specifically on reviewing six NDT techniques: Ground Penetrating Radar (GPR), Light Detection and Ranging (LiDAR)/Laser Scanning, Thermography, Ultrasound, Close-Range Photogrammetry and Through Wall Imaging Radar (TWIR). The aim is to identify knowledge gaps in terms of their use in accurately characterizing envelope compositions for further integration in Building Energy Modeling (BEM). Each technique was evaluated according to set categories imbibed from the American Society of Heating, Refrigerating, and Air Conditioning Engineering (ASHRAE) Standard 211P that showcase the technique’s ability to extract various relevant information. A framework is then developed to inform users on how to use hybrid NDT-based workflows applied in building envelope energy audits. The paper concludes by discussing possibilities of utilizing NDT in large-scale audit automation, BEM integration, and developing built environment policies focusing on increasing existing building performance through retrofitting design.

了解建筑围护结构的热力学是建筑科学的重要基础，这主要是由于围护结构作为外部环境的边界层以及内部微气候的容器和调节器的作用。本文介绍了范围广泛的文献综述，介绍了用于建筑围护结构扫描和测量以进行热力学诊断的精选无损检测（NDT）技术。该调查专门针对六种无损检测技术：探地雷达（GPR），光探测与测距（LiDAR）/激光扫描，热成像，超声，近距离摄影测量法和穿墙成像雷达（TWIR）。目的是根据知识缺口的用途来识别知识缺口，以准确表征信封成分，以进一步集成到建筑能源模型（BEM）中。根据从美国供热，制冷和空调工程学会（ASHRAE）标准211P汲取的设定类别对每种技术进行了评估，这些类别展示了该技术提取各种相关信息的能力。然后开发一个框架，以告知用户如何使用在建筑围护结构能源审核中应用的基于混合NDT的工作流。本文最后讨论了在大型审计自动化，BEM集成中利用NDT的可能性，以及着重于通过翻新设计来提高现有建筑性能的建筑环境政策的开发。然后开发一个框架，以告知用户如何使用在建筑围护结构能源审核中应用的基于混合NDT的工作流。本文最后讨论了在大型审计自动化，BEM集成中利用NDT的可能性，以及着重于通过翻新设计来提高现有建筑性能的建筑环境政策的开发。然后开发一个框架，以告知用户如何使用在建筑围护结构能源审核中应用的基于混合NDT的工作流。本文最后讨论了在大型审计自动化，BEM集成中利用NDT的可能性，以及着重于通过翻新设计来提高现有建筑性能的建筑环境政策的开发。
