Modulating Natural Ventilation to Enhance Resilience Through Nozzle Profiles
MetadataShow full item record
This study aimed to develop and test an environmentally friendly, easily deployable, and affordable façade solution for socio-economically challenged populations of the world. The façade system would modulate air velocity by utilizing natural cross ventilation techniques in order to improve human comfort in buildings. Constrained by seasonal weather and interior partitions which block the ability to cross ventilate, buildings can be equipped to perform at reduced energy loads and improved internal human comfort by using a façade system composed of retractable nozzle-forms developed through this empirical research. Drawing inspiration from a simple yet innovative idea of a powerless air-cooler developed in Bangladesh, this research investigated the efficiency of velocity-moderated evaporative cooling method by using a two-step development process of physical experimentation and software simulations. A velocity increase of 4.74 m/s was achieved through modulating profiles of nozzle-forms. Natural ventilation and cross ventilation have been used well in architectural design thus far, however, these techniques have never been harnessed to modulate the speed of incoming wind into built spaces to improve building resilience. This study is an attempt to fill this gap.
