Description

As an emerging energy-efficient ventilation system, a highvolume, low-speed (HVLS) fan system is considered an effective means of cutting down energy consumption and building operation cost. This study adopts an engineered performance-based approach with the aid of a computational fluid dynamics (CFD) modeling tool to evaluate the potential fire hazard posed by this innovative technology. A systematic study is performed to find what types of fire hazards can be caused by a HVLS fan system andhowsuch a fan systemmayadversely affect the functionality of fire detection systems and smoke spread at the early stage of a fire in a large space. It demonstrates that energy-savingHVLS fans may cause delay in fire detection and aggravate smoke spread and therefore expose occupants to a hazardous environment. It is expected that amendments in future editions of building codes and standards will address fire life safety risks posed byHVLSfan systems and provide regulations and guidelines for the design and installation of these systems.
