I understand that for densely occupied spaces an alarm (visible or audible) is required. If a sensor was installed in the room, but instead of beeping/flashing it would increase the ventilation rate when CO2 is exceeded by 10 % over the set point? Could that be a way of meeting the credit intent? (We have complex ventilation systems with 100 % outdoor air and heat recovery, and most owners find the alarms being just a show and they don’t want them).

Best regards
