We have a leased office in a LEED C&S project. As a part of the C&S scope, the building has two centrifugal fan boxes that supply 100% outdoor air to the offices through a masonry duct, this system has an airflow device at the outdoor air intake to ensure that the building ventilation system maintain design minimum requirements.
For the office, we have to extend the metal duct provided by the building ventilation system and install ventilation grilles for each space. This metal duct has a damper and has been dimensioned to provide the required ventilation rate according to ASHRAE 62.1.
Is it necessary to install an additional airflow monitoring device to meet the IEQc1 credit requirements for a LEED CI office?
