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.**

申请人西奥多·斯塔托普洛斯（Theodore Stathopoulos）教授在1980年代初设计并建立了安装在康科迪亚大学建筑空气动力学实验室中的边界层风洞。自建立以来，风洞已被用于研究所有风能建设相互作用，例如确定建筑物的风压力，对建筑物配置周围的风环境的评估，建筑物发出的污染物的分散物的评估，建筑物中的通风以及建筑物中的通风以及所有与风能的风能相关问题，包括风能电力的评估。申请人将他的研究集中在对建筑物的风影响评估上，并有助于提高其基本理解。这项研究的结果清楚地参与了风力标准的规定以及包括加拿大国家建筑法规（NBCC）在内的不同国家的实践守则。所请求的研究工具和仪器由4264（微型压力扫描仪）的四个单位及其设置配件组成。与当前ZOC33/DSM34000系统相比，使用MPS 4264有很多好处，该系统将克服一些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的风负载方面是新颖的（太阳能电池板，檐篷，修道，阳台等）。风构建法规和标准正在急切地等待这些特定研究的研究结果，以生成相关的设计规定。同样，在相关学生的论文中，实现所需的进展在很大程度上取决于升级风压测量仪器，从而可以进行风洞实验研究。有必要指出，研究学生可以轻松获得MPS 4264的掌握，并可以通过研究数据收集和可追溯性保持最新。
