Hi,
Our project consists of office building and workshop which is going for LEED v3 2009.
The workshop is 105 feet wide, which is not able to compliance for IEQ Prerequisite 1 using operable windows (25 feet) as per ASHRAE 62.1 2007. But if we follow ASHRAE 62.1 2013, we can achieve natural ventilation for the workshop building with respect to ceiling height (Section 6.4).
My query is if we follow ASHRAE 62.1 2013 as per LEED Interpretation ID# 10416 for EQ Prerequisite Minimum Indoor Air Quality Performance and EQ Credit Increased Ventilation it won't affect other credits (Like we follow ASHRAE 90.1 2007 & ASHRAE 55 2007 for other credits) right????
Please Clarify,
Thanks,
Andrew Mitchell, P.E.

Based on my understanding of the exceptions 2a and 2b in 6.4, you would need to have the space not be heated or cooled and also have the openings be permanent or automatically opened if you want to comply with 2013.

dear all....i have similar issue, the calculation of minimum supply air flow & Ventilation effeciency is very clear and simple in ASHRAE 62.1-2019 as the same calculations is complicated is ASHRAE 62.1-2007 so, Can i use the ASHRAE 62.1-2019 version to apply IEQ Pr-01 in LEED v3 2009 ??
