Hi,
Our project is mechanically ventilated by 100% OA constant volume enthalpy heat recovery ventilator. Regarding monitoring, according to LEED reference guide, in our case, monitoring by current transducer on the supply fan, an air flow switch, or similar monitoring device is acceptable. In order to meet the requirement, is it OK to monitor just the ventilation fan is operated or not, or is measurement required? Any comment would be appreciated.
