Typical Layouts

Education buildings are typically designed with an atria in the main central spine of the building, to create natural light into surrounding classrooms and communal areas, to promote a productive learning environment for students.

Such spaces provide a significant challenge to the fire protection design teams due to the typical openness, height of the building and the ability for the smoke to spread from floor to floor. Evacuation routes for students and pupils in these areas provide a significant concern, unless an effective smoke control system is implemented.

Typical Strategies

The smoke control strategy within atria is designed to create a smoke free layer above the floor by removing smoke from the building. This is achieved by using the natural buoyancy of the hot gases to rise and exhaust through high level vents whilst introducing replacement fresh air via low level inlet vents. This process creates a smoke free layer at a sufficient height below the ceiling to achieve safe evacuation of the students and staff and to provide good visibility for the fire fighters to enter the affected areas.
