We are having query related to prerequisite requirement of monitoring in LEED BD+C V4. 

We are planning to install 'Direct Evaporative cooling system' with HVLS (high volume low speed) fans for manufacturing area of approx. 1200 sq.m. We will be installing 12 Evaporative cooling units in this area. The louvers at the bottom of the wall will work as outlet of the air. This is 100% fresh air system and There are no specific guidelines mentioned for this system in ASHRAE 62.1 2010

Our query is,do we need any monitoring system for this kind of a system? and if yes, Do we need to install outdoor air delivery monitoring system for each unit? As the cost of the monitoring is more than the system cost. 

We have kept on hold our LEED project registration because of this major cost implication.
