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

DCV

Hallo, I am reading Section 6.2.7 ASHRAE 62.1-2010, and it is not clear to me if the building needs to install DCV. In case this is mandatory, is it required for every tenant? Verbatim from the Standard: 6.2.7. Dynamic Reset. The system may be designed to reset the outdoor air intake flow and/or space or ventilation zone airflow as operating conditions change. 6.2.7.1 DCV 6.2.7.1.1 DCV shall be permitted as an optional means of dynamic reset.

Hi Gustavo, The standard does not require DCV and it is not required to be installed in the building for LEED. The standard identifies dynamic reset as an optional component of the ventilation system and DCV as a method by which to implement the dynamic reset strategy.
