Wind problems, such as those affecting pedestrian comfort, door operability and air quality & ventilation, can damage the public image of a building and negatively affect people’s comfort and safety. For many building owners and users, these existing wind problems are often blamed on mother nature. In reality, they can be created by various factors, including changes in usage of pedestrian areas, variations in buildings and surroundings, deterioration of door hardware and HVAC systems, increased awareness and sensitivity to user comfort and/or poor design. Measures are often readily available to mitigate these problems and can readily be implemented during routine renovations or specific retrofits. Optimum solutions can be developed by using various tools, while taking into consideration the local climate, the existing design of buildings, landscaping and mechanical systems, together with engineering knowledge, judgement and experience.
- develop an understanding of general flow patterns around buildings, and the resultant wind speeds, pressures and forces that may create wind problems;
- review the engineering tools that are often used to solve wind problems, such as experienced based desktop analysis, Computational Fluid Dynamic (CFD) simulation, and scale model testing in a boundary-layer wind tunnel; and,
- use case studies of real projects to illustrate typical retrofitting strategies and their effectiveness in improving pedestrian comfort and building performance.
