Calculating airflow from window opening to assess natural ventilation

Dear all,

I am trying to assess window-based natural ventilation, so is there a method to calculate airflow from an opened window (a certain opening ratio or area, 50%)?

Also, I want to find how much air is needed to enter a space to maintain CO2 level under 1000 ppm, is there a way to measure indoor CO2 concentration? Or setting natural ventilation based on CO2 level rather than temperature?

Thanks for your help in advance.

Hi, have yoy found the solution to this yet?

Hey @HardiBarznji

Were you able to figure out a work-around to record the CO2 levels?

Cheers
