    Smoke extract system & staircase press. System
    I am working for a 35 storey tower. There are smoke extract and staircase/lift lobby pressurisation system in case of fire. Now consultant has already given the CFM required for these Fans, but I have to submit the calculations for the same to the Local Govt. authority.

    So please help me if someone knows the calculation for the same.

    Please tell me if any additional data is required.
