Underground Concrete Return air Plenum
Underground Concrete Return air Plenum
(OP)
Dear All,
I would like to know the possibility of using underground concrete plenum as return air plenum for my ongoing factory project without any sheet metal duct work.
Is there any issue related with condensation or formation of mold or any infection related issues which can cause any significant problem. Please advise.

You are judged not by what you know, but by what you can do.

Hi Berkshire,
I would like to use underground concrete plenum as return air plenum as I am not using any galvanized duct work. Off course galvanized drain piping will be considered in this concrete plenum.
Do we have any code which says underground concrete plenum can be used as return air plenum. please advise.
