Dear all,

Our project is a big mall, with the roof being utilized as restaurants, play area, a cinema complex, a green vegetated area, and some technical areas.

Accordingly, this area will be maintained and cleaned on a daily basis. In addition, the roof will be accessed from the floor below only, and hence can confidently be considered as a space within the mall with no connections to the outside.

My question is: Can we exclude the roof entrances from the "Indoor Chemical & Pollutant Source Control" credit? It is not physically feasible to install permanent entryway systems on the entrances between the open roof and the closed mall portion (cinema complex & escalator's lobby).

I believe that we can exclude permanent entryways. Any suggestions?

Many thanks!
