FAQs about IEQp1 :

What if after our Preliminary Review we have to re-work the ventilation rate procedure calculations and find that we need to make corrections to the system in order to meet the prerequisite? Can we redo the outside air testing after making corrections? Wo

What if our systems do not meet the required outside air when systems are tested at worst-case conditions?

Our building has a single fan that supplies outside air to multiple AHU’s. Do we need to perform outside air testing at the supply fan or at all AHUs?

We have a VAV system where single AHUs serve multiple zones. Do we need to take outside air measurements at each VAV box?

EBOM-2009 IEQp1:Minimum IAQ Performance

System status report for ventilation system

We are pursuing LEED-EB:O&M for an office building. It has BAS functions for heating, ventilating, and air conditioning system. To comply with the prerequisite requirements, we provided a ventilation air flow summary, as well as maintenance logs, a preventative maintenance plan, and test reports. Additionally, please guide us with samples how to provide a periodic system status report for any portions of the ventilation system regulated by the building automation system. Thank you!

Monthly screen shots, during the performance period, showing the fresh air damper is open during occupied times and closed during unoccupied modes would suffice. Or, provide a narrative from the responsible party stating they have used the BAS system regulary to ensure that fresh air dampers are operating in accordance with the documented sequence of operations. The intent is to verify the ventilation system is working correctly during the performance period. Hope this helps.

Just confirming... Does this mean that if there is a BAS in place that already in place that measures OA, CO2, airflow etc, no physical testing or balancing at the AHU/VAV level has to be conducted unless an issues comes up that it does not meet the 62.1 levels? Thank you in advanced
