The Building Aerodynamics Laboratory of Concordia University located at the Engineering complex, houses a large atmospheric boundary layer wind tunnel (ABLWT), the only one of this type in Quebec and one of the very few in North America. It is an open circuit, blow down tunnel 12 meters long and has a test section 1.8 meters wide by 1.8 meters high. Models of buildings and their surroundings are constructed at a geometric scale (typically 1:500 to 1:200) and placed on a turntable downstream of the incoming flow, which simulates the natural wind characteristics when wind blows towards from any direction. The ABLWT has been equipped with sensitive sensors and instruments used for accurate measurements of flow and pressure components depending on the particular application of interest. The facility has been used for numerous research studies with significant contributions in the field of wind engineering, mainly in the development of wind loading provisions for wind standards and building codes of practice around the world. Several hundreds of students, researchers, architects and engineers have been benefited by this facility in the course of the last 30 years.

康科迪亚大学建筑空气动力学实验室位于工程综合体，拥有一个大型大气边界层风洞（ABLWT），这是魁北克省唯一的此类风洞，也是北美极少数的风洞之一。这是一条长 12 米的开放式排污隧道，测试段宽 1.8 米，高 1.8 米。以几何比例（通常为1：500至1：200）构建建筑物及其周围环境的模型，并将其放置在来流下游的转盘上，模拟风从任何方向吹来时的自然风特性。 ABLWT 配备了灵敏的传感器和仪器，用于根据感兴趣的特定应用精确测量流量和压力分量。该设施已用于众多研究工作，在风工程领域做出了重大贡献，主要是为世界各地的风标准和建筑实践规范制定风荷载规定。在过去 30 年里，数百名学生、研究人员、建筑师和工程师从该设施中受益。
