Wind direction site analysis is a crucial tool for understanding prevailing winds and their influence on an area, with applications in improving outdoor spaces, harnessing wind energy, and identifying potential issues early on. This analysis provides architects and engineers with data necessary for informed decisions about building design, ventilation, and safety, using instruments like anemometers and advanced simulations such as computational fluid dynamics (CFD). By mapping wind direction and speed, planners can create energy-efficient structures that withstand changing conditions, optimize urban environments for pedestrian comfort, and ensure effective pollution control and natural ventilation. Different types of wind analyses, including wind comfort, wind loading, and air quality assessments, cater to specific goals, depending on project needs. The process involves collecting wind data from local weather stations, interpreting wind roses, and utilizing digital tools like GIS to simulate and visualize airflow patterns, ultimately leading to better architectural and urban planning decisions. Platforms like Felt's Web GIS simplify this process, offering tools for spatial analysis and insights that help design safer, more comfortable environments while enhancing workflow efficiency.
