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 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?

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 due to design limitations. What should we do?

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

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?

EBOM-v4.1 EQp1:Minimum Indoor Air Quality

MERV 8 upstream cooling coils

Hi,

We are working in an EBOM v4.1 project. I have one question.

- According to ASHRAE 62.1-2016, Section 5.8, Particulate Matter Removal, MERV8 filters should be placed upstream cooling coils.

The HVAC system is existing and will not be modified during the upgrade of the building. Many of the evaporator units and AHU´s cannot work with MERV8 filters, as it is prescribed in ASHRAE 62.1-2016.

- Is this a prerequisite as it is in BD+C?

- Will the builging be able to certify even if they don´t count with MERV8 filters upstream the cooling coils?

Thank you,

Hi Paula In LEED O+M v4.1, you only have to comply with sections 6.2 (VRP) and 8.2 (O&M) for mechanical ventilation, according to this reference guide. The filter efficiency is not verified by this reference guide. It is required for LEED BD+C Projects. Regards.

Thank you Patrick!
