Calculations For Commercial
Roof Vents – Size & Number
1. Determine the volume of the building
Volume of section A = 0.5 x L x W x Ha
Volume of section B = L x W x Hb
Calculating Total Building Volume
Add the Volume of section A + Volume of section B
Note: For factories, the combined volume A + B should be used.
Where Volume B is air-conditioned, only Volume A is used
to calculate the number of ventilators required. No air
should be drawn from the air-conditioned space below
2. Select the number of ventilators required
METRIC = V x Ac/Hr. EX/c x 3.6
V = Volume of building or roof space
Ac/Hr = Air changes per hour
EX/c = Exhaust capacity of ventilator
Using ventilators in the ceiling space of air-conditioned buildings reduces the load on the air-conditioning plant and helps reduce power consumption accordingly. Well worth the initial investment for vents and installation cost.
