The project we are working on is a shopping mall. We are calculating airflow rates according to ASHRAE standard. Can you tell me if the area surrounding all the shops inside the mall can be clasified as "Corridors" (ASHRAE 62.1-2007, Table 6-1) or should it be clasified as "Common mall areas". The thing is that requirements for "Common mall areas" are very strict, 40 people per 100square meters seems to be to much. Our designers were conducting their calculations for lower occupant densities. And one more thing: what minimum ventilation rates should we use for cinemas?

We are always use mall common area for these, it seems The review team is agree with this always.

I agree that the "Common Mall Areas" space type is appropriate. The corridor definitions hould only be applied to back-of-house areas, where there is substantially less occupant traffic.

The thing is that occupant density for "mall common area" is very high - 40people per100m2. This is much more than we assumed in our project. Can we uncheck the default box under occupant density in the LEED online form (only for mall common area) and put a value that our designers are using based on data from previous similar projects that are already in use? For other spaces we would use default occupancy desities.

Hi Adam, can I ask you if your approach for Mall common areas "unchecking the default occupant density" was accepted by USGBC? we have a similar situation, Thank you
