The applicant, Prof. Theodore Stathopoulos, has designed and established Boundary Layer Wind Tunnel installed in the Building Aerodynamics Laboratory of Concordia University in early 1980s. Since its establishment, the wind tunnel has been used for the study of all wind-building interactions such as the determination of wind pressures on buildings, the assessment of wind environment around building configurations, the evaluation of dispersion of pollutants emitted from buildings, the ventilation in buildings and all wind-related issues in the urban environment including evaluation of wind energy potential. The applicant has focused his research on the assessment of wind effects on buildings and has contributed to the improvement of their fundamental understanding. The outcome of this research has been clearly involved in the development of provisions of wind standards and codes of practice of different countries including the National Building Code of Canada (NBCC).******The applicant aspires to upgrading the existing pressure measuring system (DSM/ZOC system) used for wind loading measurements in the boundary layer wind tunnel laboratory of Concordia University. The research tool and instrument requested consists of four units of MPS 4264 (Miniature Pressure Scanner) and their accessories for setup. There are many benefits in using the MPS 4264 over the current ZOC33/DSM34000 system that will overcome the technical limitations for conducting wind tunnel experiments required for several ongoing research projects. These research studies are novel in the evaluation of wind loads on buildings and their components (solar panels, canopies, mullions, balconies and the like). Wind building codes and standards are eagerly awaiting the research outcomes from these particular research studies in order to generate relevant design provisions. Also, the achievement of the required progress on the associated students' theses depends to a great extent on upgrading the wind pressure measurement instrumentation which allows proceeding with the wind tunnel experimental research. It is necessary to point out that research students can easily get to grips with MPS 4264 and can stay current with research data collection and traceability.******The requested instrumentation will be purchased from Scanivalve Corporation at a total cost of $ 130,557.**

申请人Theodore Stathopoulos教授于20世纪80年代初设计并建立了边界层风洞，安装在康考迪亚大学建筑空气动力学实验室。自建立以来，风洞已用于研究所有风与建筑物的相互作用，例如建筑物风压的确定、建筑物周围风环境的评估、建筑物排放污染物扩散的评估、通风状况的评估等。建筑和城市环境中所有与风相关的问题，包括风能潜力评估。申请人的研究重点是风对建筑物影响的评估，并为提高他们的基本理解做出了贡献。这项研究的成果显然参与了不同国家的风标准和实践规范的制定，包括加拿大国家建筑规范（NBCC）。 *****申请人渴望升级现有的压力测量康考迪亚大学边界层风洞实验室用于风载荷测量的系统（DSM/ZOC系统）。所需的研究工具和仪器包括四台 MPS 4264（微型压力扫描仪）及其安装附件。与当前的 ZOC33/DSM34000 系统相比，使用 MPS 4264 有很多好处，可以克服多个正在进行的研究项目所需的风洞实验的技术限制。这些研究在评估建筑物及其组件（太阳能电池板、檐篷、竖框、阳台等）的风荷载方面具有新颖性。风力建筑规范和标准正在热切地等待这些特定研究的研究成果，以便产生相关的设计规定。此外，相关学生论文所需进展的实现在很大程度上取决于风压测量仪器的升级，从而可以进行风洞实验研究。有必要指出的是，研究生可以轻松掌握 MPS 4264，并能够掌握最新的研究数据收集和可追溯性。****** 所需的仪器将从 Scanivalve Corporation 购买，总成本为 130,557 美元.**
