The Ventilation Rate per Personcalculator computes the ventilation rate per person based on the flow rate of fresh air, volume of the space, occupant density and the ceiling height.

INSTRUCTIONS: Choose units and enter the following:

• (q) This is the flow rate of fresh air into the space
• (v) This is the total volume of the space (e.g. volume of a room)
• (D) This is the area per occupant (e.g. 64 square feet)
• (h) This is the height of the ceiling

Ventilation Rate (Rp):  The calculator returns the ventilation rate in cubic feet per minute. However, that can be automatically converted to compatible units via the pull-down menu.

#### The Math / Science

R_p = (q / v) * (D*h)

where

• Rp = ventilation rate per person
• q = fresh air flow through the room (Cubic Feet per Minute,  cfm)
• v = volume of the room (Cubic Feet)
• D = occupancy density
• h = height of the ceiling
