Hi Dina, if you are using wall openings covered with fins, you can only count free area and perform calculations based on either ASR, ASHRAE, or CIBSE Standards. Apart from that, ASHRAE offers the possibility to demonstrate compliance with an engineered natural ventilation system:

Hi Dina, I wish to add based on the codes mentioned by Gustavo, basically you need to comply the followings:
- ASHRAE 62.1.2010 item 6.4.1 and 6.4.2
- CIBSE Figure 2.8 compliances
- To install CO2 sensor on each thermal block at human level with audible or blinking system when the level exceeds the set point
