Dear all,

I have a question regarding the use of smoking cabins in a LEED project, has anyone ever tried to install one or is willing to share their experience? Would the requirement be met if the cabin can provide the negative pressure difference of 5 Pa?
There is an example diagram on page 419 of the BD+C V3 reference guide, where there is an Ante-Room for the smoking room, would this requirement also be necessary given the cabin is a stand alone unit?
