Smoke Extract Design for Multi-Storey Atria

Atria create dramatic architectural spaces but require sophisticated smoke control engineering to maintain life safety.. Atrium Smoke Control Design Multi storey atria connect multiple floors and can allow rapid smoke spread throughout a building. Design Approaches 1. Natural smoke ventilation — AOVs at atrium roof 2. Mechanical smoke extract — powered exhaust fans 3. Smoke reservoir — containing smoke at ceiling level 4. Depressurisation — maintaining lower pressure in atrium 5. Channelling screens — directing smoke flow to extract points CFD Modelling CFD is essential for atria exceeding ADB prescriptive limits. Models must demonstrate smoke layer remains above 2.5m above highest occupied level for the required evacuation period. For atrium smoke control design, contact us.
