Hi,
In order to achieve EQc1 - option 1 do I still need to intall dedicated exhaust systems to all spaces where are hazardous gases are present? In LEED v2009 (IEQc5) this was mandatory. However, in LEED V4 (EQc1 - option 1), I am not seeing this requirement. Please clarify if this is stil mandatory or not on LEED v4.
Thank you all in advance!

If you read the detail in the v4 reference guide, the Enhanced IAQ Strategy credit still requires negative pressure and exhaust with no recirculation of the air from these spaces. Under the credit it also addresses stacking these locations to minimize ductwork and locating them close to an exterior wall. From this information I infer that the exhaust must be to the outdoors.

Hi Stephanie and thank you for your answer.
That is true, but it is only a sugestion for energy economy.
If this part of the credit only requires for negative pressure, may the exhaust system also exhaust air from other spaces (office, per example)?
My question is: is it MANDATORY to have a DEDICATED exhaust ventilator per space with hazardous gases (or one system per group of spaces with the same contaminant)?
Hope I made myself clear,
Thank you all in advance!

As long as it exhausts to the outdoors, the exhaust can be combined with exhaust from other spaces. This is allowed. Example: often the janitor closet exhaust is exhausted with the toilet room exhaust.
