Note:

The required ventilation rate (Q) is an essential factor in maintaining good indoor air quality. It determines the amount of fresh air needed per second to ensure a healthy and comfortable environment. Proper ventilation helps in reducing indoor pollutants, controlling humidity levels, and ensuring adequate oxygen supply.

Parameters Explanation

• Q: Required ventilation rate (L/s) - The total volume of fresh air required per second to ensure proper indoor air quality.
• N: Number of occupants - The total number of people present in the space.
• R: Ventilation rate per person (L/s per person) - The amount of fresh air required per person to maintain air quality.
