Principles


Typical Layouts

Modern hospitals often utilise central atria to bring natural light into the building – and all the health benefits of additional daylight. The Atrium can be used to provide additional safety benefits of smoke ventilation and health benefits of natural ventilation.

Fire fighting cores are used in tall buildings, buildings with deep basements, and buildings with large floor areas, to provide safe access for the fire service to enter the affected floor and act accordingly and require a form of smoke ventilation.

Typical Strategies

The priority design requirement in any life safety smoke ventilation system is to provide a safe means of escape for occupants through maintaining tenable escape conditions. This can be achieved by either natural or powered smoke extraction systems, within the atria or fire fighting cores. Depending on the building layout, natural ventilation systems in atria would typically use high level openings in the roof or upstand by utilising the smoke’s natural buoyancy. Mechanical smoke ventilation systems use powered fans to aid in the extraction of smoke.
