268: Ventilation Performance in a Funneling Window

Colima, (latitude 19º15'; longitude 103º44', altitude 450m) is a small city in the mid-western coast of Mexico with a warm sub-humid climate. Under these weather conditions, one of the main strategies of bioclimatic adaptation is natural ventilation. However, in some seasons the wind speed is not enough to generate relative thermal comfort, primarily during the summer months. Summers in Colima are seasons of high temperatures, and low wind speeds, for that reason it is required to not only think of having appropriate orientations and dimensions for openings to capture wind, but to also think of the need of incorporating mechanisms that increase the wind speed. Due to this, improving the local comfort conditions through a passive system, located in the window itself, will increase external wind velocity. The potential use of a reception and concentration system of the wind was determined. The resulted method was that the window design itself could modify the velocity and direction of the wind. It was determined that by using flat surfaces it was possible to manipulate the mechanics of the wind to improve the ventilation conditions of the inhabited space and in
