This project examines questions regarding wind pressure on roofs, around a building site, and in entry vestibules. The problems that arose consisted of high pressure areas on the roof, snow drifts developing in undesirable locations, and interior ceiling tiles in the vestibule blowing out of their tracks because of high wind pressure. The simulations performed sought to determine the location and amount of the highest wind pressure exerted on the roof’s surface as well as in the vestibule. This study also analyzed the impact that the inclusion of an outlet had for the wind.
