Résumé

Typically fire safety design of ventilation systems use fire and smoke dampers on ducts to each fire compartment or separate ventilation systems for each fire compartment. These solutions are generally referred to as prescriptive solutions (also known as deemed-to-satisfy solutions under the National Construction Code).

Less known are analytical methods that use simulations to allow a designer to predict the fire’s effect on the building’s ventilation system. These methods predict the flow and temperature of hot gases entering the ventilation system. This allows a ventilation system design with the fan(s) operating during a fire and where the operation of the fan is able to prevent fire and smoke spread in the building via the ventilation system.

This paper uses a case study for a single-storey building to demonstrate how such simulations were used to justify the omission of smoke and fire dampers from the ventilation system design. The construction cost savings associated with the engineered design was approximately $200–$300K.
