Calculates the potential CO₂ concentration in a room based on the number of people, room volume, and ventilation rate.
Start with your values, or try a preset.
Enter Number of People in the Room, Room Volume, Ventilation Rate, and Outdoor CO₂ Concentration in the units shown.
Read Ventilation Volume, CO₂ Emission Rate, CO₂ Concentration Increase, and Final CO₂ Concentration in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
