Determine the quantity of Wind Driven Ventilators required to ventilate a specific building effectively.
Calculate the volume of the building
Select the Air Rate Change required for your specific building
Air rate changes per hour is the volume of air that needs to be replaced with fresh air every hour. Select the air rate change required for your specific building indicated in the Table - A : Recommended Air Rate Change per Hour (ACH).
[Refer to ACH table below Step 4]
e.g. Assembly Hall : 06 - 12 air changes required.
Average Air Rate Changes per Hour = 09 (approximate)
Multiply the Volume (step 1) by the Number of Air Changes required (step 2)
Determine the Size and Quantity of Wind Driven Ventilators required for the above building
Select Wind Ventilator Size & enter CFM value
Total Unit of Wind Ventilator required for building :
