Hi,
our project is mixed use commercial building, including office, hotel, retail store, and restaurant etc. All spaces in our project comply with ASHRAE 55 except for commercial kitchen. There is no AC unit there and conditioned air is delivered from adjacent restaurant dining room and exhausted through fan located in the commercial kichen. So the kitchen air is conditioned indirectly. Our question is that the commercial kitchen may excluded from ASHRAE55 evaluation or not. Thank you for your kind advice in advance.
