FAQs about EQp1 :

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

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

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

What if after our Preliminary Review we have to revise 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? Wou

My building has 80 AHUs providing ventilation to building spaces. Do I have to do the ventilation calculations and conduct outdoor air measurements for each one?

Our system cannot provide enough outdoor air to meet ASHRAE 62.1-2010 due to design limitations. How much outdoor air must we provide to meet Case 2 instead?

The outdoor air intake for our ventilation system is not accessible, and it’s not possible to measure the outdoor airflow directly. How can we determine the outdoor airflow for this system?

How do I find whether my project is located in a non-attainment area for particulate matter or exceeds the prerequisite ozone requirements?

What happened to the IEQ Space Matrix that was available to version 2009 projects? What should I reference to determine how spaces in my building should be categorized for this prerequisite?

EBOM-v4 EQp1:Minimum indoor air quality performance

MERV filters

Is there any mandatory filter efficiency requirement (MERV) for projects located in areas with a very high PM2.5 levels? Is it mandatory for ASHRAE 62.1-2010 requirements?

I do believe that Std 62.1-2010 includes MERV rating requirements for buildings in non-attainment regions. But, I'm not sure that GBCI will request documentation of MERV efficiency under this prerequisite.
