How to Use This Calculator

Enter measured CO2 level (ppm), temperature (°C), and relative humidity (%).
Enter number of occupants and room area (m2).
Read the composite indoor air quality score and ASHRAE 62.1 ventilation adequacy assessment.
CO2 above 1000 ppm often indicates inadequate ventilation; above 1500 ppm is poor air quality.
Review recommended fresh air supply rate (L/s/person) to achieve acceptable CO2 levels.
