We have a single space in our building (entrance lobby) that is being naturally ventilated through the revolving doors at the main building entrance. How can you calculate the room-by-room airflow in this case for compliance with Option 2 of this credit? Or is there any prescription in CIBSE AM10 for such a case that we may use to show compliance with Option 1 of this credit? Thanks.

Omer, could you provide more details on the lobby and the location of the project? I haven't seen a project try to comply with ASHRAE 62 using revolving doors in the past.

Here's an interesting reference: Min, T. C. “Winter infiltration th rough swinging-door entrances in mult i-story buildings.” Heating, Piping and Air Conditioning 30.2 (1958). I found it reading a paper on a study on revolving doors. http://web.mit.edu/~slanou/www/shared_documents/366_06_REVOLVING_DOOR.pdf It looks like a revolving door can bring 1700 to 3000 m3/h (I found that quite supprising). It is obviously highly traffic dependant.
