Investigation of building envelope performance

为了使建筑以最低的能耗和耐用性提供所需的室内环境，必须了解、测量和控制建筑围护结构中的热、空气和湿度(HAM)流动。这项研究的目标是通过下列项目增加建筑围护结构中的知识库和毕业专业人员：1.由申请人发起的测试方法将首次量化“气候负荷”和墙体系统在立柱空腔中受到水入侵的响应关系，将被使用和扩展(I)制定一个共同的尺度或标准，以便可以比较和改进不同建筑围护结构的相对性能，以及(Ii)将建筑围护结构设计进一步推向工程方法，以提高性能。从SRO(特殊研究机会)产生的数据集将被使用和扩展，以更好地了解室外环境、建筑围护结构和室内环境之间的相互作用。将利用信息技术继续开发工具，对建筑围护结构和建筑系统进行全面评价。这类工具将特别有助于工业化住房制造商建立和改进其产品的性能，以供世界出口。与华格博士的合作将继续巩固温哥华的建筑工程基地。实验结果以及上述项目将获得的结果将通过应用现有分析方法的原理(如极限状态设计)进行推广。这些数据还将用于与过去开发过计算机模型的同事合作验证计算机模型。

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.
