Room Ventilation Calculator: Area Method

The calculation is designed to help you calculate the required rate of ventilation in a room based on the size of the room.

Calculations

Inputs



Ventilation Rate per Square Metre
:0.3​



Area of Space
:7m2​


Output



Rate of Ventilation, L/s
:2.1​


Explanation

Rate of ventilation in a room refers to the amount of air that is exchanged in the space between the outside environment and the interior of the room over a given period of time. This calculator uses the area of the room and the required ventilation rate per square metre to calculate the required rate of ventilation.

RV=AR∗VrR_V = A_R*V_r
Where:

RV=Overall Rate of Ventilation (Ls−1)AR=Area of Room (m2) Vr=Ventilation Rate per Square Metre (Ls−1m−2)R_V=Overall \: Rate \: of \: Ventilation \: (Ls^{-1}) \\A_R=Area \: of \: Room\: (m^2) \: \\ V_r=Ventilation \: Rate \: per \: Square \: Metre \: (Ls^{-1}m^{-2})
💡 Make sure to check recommendations and standards for ventilation rate per square meter depending on your particular situation.
