Smoke removal in multi-storey building
Smoke removal in multi-storey building
(OP)
What code does it pertain? What is the requirement in term of designing the extract airflow requirement? Does the existing extract fan suitable enough? Is this option only?

- Atriums over 2 stories in height (IBC Section 404.4)
- Covered malls constructed as atriums over 2 stories in height (IBC Section 402.9)
- Smoke proof exit enclosures in high rise buildings (IBC Section 403.13)
- Underground buildings (IBC Section 402.5)
You have not indicated if this is an active or passive system, although your description causes me to believe it is an active system. In this case, see IBC Section 909 for design criteria.
If you are outside the US and the country has not adopted the IBC, you'll probably apply NFPA 92B, Standard for Smoke Management Systems in Malls, Atria and Large Spaces.
