Greetings,

There is a question regarding the requirements related to DCV – 6.4.3.8 and specifically Exception 4. – “Spaces where >75% of the space design OA is required for makeup air…”.

The question is: If we have a 100% OA situation, or DOA (Dedicated Outdoor Air) unit, do such cases belong to this exception and therefore providing DCV conditions are not required.

Your comments are highly appreciated.

Thanks.
