I would like to ask if there's any requirement regarding outdoor air suplly to a kitchen located in an office area? In ASHRAE 62.1-2007 Table 6-1 a kitchen is not mentioned. However in 62MZCalc file you can choose "Kitchen (cooking)" as a zone type. What is the requirement for kitchens regarding amount of resh air?
My client has an office where there is a kitchen (around 12 square meters) without outdoor air supply, there's only exhaust installation. I'm not sure what to do about this. Does it mean that the requirements of this prerequisite are not complied with.

Adam,
Kitchens have an exhaust air requirement (Table 6-4) rather than an outdoor air requirement. The kitchen you're referring to sounds more like the kitchenette occupancy category than a commercial kitchen, so the exhaust rate would likely need to meet the 0.3 cfm/sf requirement in Table 6-4. As stated in Section 6.2.8, the exhaust makeup air does not need to be outdoor air, but can be any combination of outdoor air, recirculated air, and transfer air.
