For a building to provide the desired indoor environment at minimum cost in terms of energy and durability, the flow of heat, air, and moisture (HAM) across the building envelope must be understood, measured and controlled. The objectives of this research aim to increase the knowledge base and graduate professionals in the building envelope through the projects listed below:1. The test method, initiated by the applicant to quantify for the first time "climatic load" and response relationships of wall systems subjected to water intrusion in the stud cavity, will be used and extended (i) to develop a common yardstick or standard whereby the relative performance of different building envelope configurations can be compared and improved and (ii) to move building envelope design further towards the engineering approach to enhance performance.2. The data sets generated from the SRO (special research opportunity) will be used and extended to gain a better understanding of the interaction of the outdoor environment, the building envelope, and the indoor environment.3. Development of tools will be continued using Information Technology (IT) to carry out comprehensive evaluations of building envelope and building systems. Such tools will be particularly useful to manufacturers of industrialized housing to establish and improve the performance of their products for world export.4. Collaboration with Dr. Hua Ge will be continued to consolidate a Building Engineering base in Vancouver.The experimental results along with the results that will have been obtained from the above projects will be generalized by applying principles of existing analytical methods such as limit state design. The data will also be used to validate computer models in collaboration with colleagues who have developed such models in the past.

为了使建筑物在能源和耐久性方面以最低成本提供所需的室内环境，必须了解、测量和控制穿过建筑物围护结构的热、空气和水分（HAM）的流动。本研究的目标是通过以下项目增加建筑外壳中的知识基础和研究生专业人员：1.该试验方法由申请人发起，首次量化了“气候荷载”和墙系统在水侵入立柱空腔时的响应关系，将被用于和扩展（i）制定一个共同的尺度或标准，从而可以比较和改进不同建筑围护结构的相对性能，以及（ii）使建筑围护结构设计进一步向工程化方向发展，以提高性能。从SRO（特殊研究机会）生成的数据集将被使用和扩展，以更好地了解室外环境，建筑物围护结构和室内环境的相互作用。将继续利用信息技术开发工具，对建筑物外壳和建筑系统进行全面评价。这些工具将特别有助于工业化住房的制造商建立和改善其产品的性能，以供世界出口。与华戈博士的合作将继续巩固在温哥华的建筑工程基地。实验结果沿着将从上述项目中获得的结果将通过应用现有的分析方法如极限状态设计的原理来推广。这些数据还将用于与过去开发此类模型的同事合作验证计算机模型。
