Nondestructive testing is in important method when commissioning and testing materials and assemblies ofnew and existing buildings. Infrared thermography is a key tool used when evaluating the performance of abuilding and when identifying deficiencies and problems. Infrared thermography capturing full radiometricvideos allow for the capture and analysis of transient and transitional thermal effects within materials andassemblies. New methods for using infrared thermography are being identified in the electrical, electronic,manufacturing and aerospace fields. Acoustic performance of materials, assemblies and spaces are becoming ofgreater importance as urban densification is improved as a result of climate change. The National BuildingCode of Canada prescribes three methods for demonstration of compliance with acoustic requirements: field measurement; prescriptive procedure; and design procedure. Due to the requirement of the building to beconstructed before conducting field measurements, as well as the cost of testing, designers typically use theprescriptive procedure or design procedure, but real work actuals of the assemblies, space usage and external factors may result in unwanted noise pollution.Indoor air quality and occupant health is a growing concern with the push for increased energy efficiency ofbuildings. Increased energy efficiency usually includes the tightening of the building envelope by reducingpoints of air egress of ingress. This reduction can lead to poor indoor air quality as less fresh air may beentering the space from either controlled or uncontrolled means. Common indoor air quality pollutants such as volatile organic compounds (VOC), Nitrogren Dioxide, Carbon Monoxide, Radon and others can bedetrimental to the health of occupants. Healthier workplace indoor air quality improves worker productivitythrough reduced lost time due to health problems, and improved output.

无损检测是对新建和现有建筑物的材料和组件进行调试和测试的重要方法。红外热成像是评估建筑物性能和识别缺陷和问题时使用的关键工具。红外热成像捕捉全辐射视频允许捕捉和分析材料和组件内的瞬态和过渡热效应。在电气、电子、制造和航空航天领域，正在确定使用红外热成像的新方法。随着气候变化导致城市密度的提高，材料、组件和空间的声学性能变得越来越重要。加拿大国家建筑规范规定了三种证明符合声学要求的方法：现场测量;规定程序;和设计程序。由于建筑物的建造需要在进行现场测试之前进行，以及测试的成本，设计人员通常使用规定的程序或设计程序，但组件的真实的工作实际情况，空间使用和外部因素可能会导致不必要的噪声污染。提高能源效率通常包括通过减少空气出口或入口来收紧建筑物的围护结构。这种减少会导致室内空气质量差，因为较少的新鲜空气可能从受控或不受控的方式进入空间。常见的室内空气质量污染物，如挥发性有机化合物（VOC），二氧化氮，一氧化碳，氡等，都可能对居住者的健康有害。更健康的工作场所室内空气质量通过减少因健康问题而损失的时间和提高产量来提高工人的生产力。
