Hello,

In order to assess compliance of a Data Center with prerrequisite EQp1 and credit EQc1, I would like to know how we should calculate fresh air needs for the server rooms.

Indeed, in the context of prerrequisite EQp1 and credit EQc1, we have considered no needs for server rooms because the owner has specified that those spaces would be inoccupied all the time. This considered, the only spaces with fresh air needs associated with the ventilators of server rooms would be the corridors and vestibules adjacent to server rooms.

This consideration permited to calculate that the amount of fresh air injected was sufficient to achieve compliance with LEED requirements. However, if specific needs of exterior fresh air supply would have to be considered for server rooms, the compliance of current systems would be compromised.

How to classify server rooms? Is no fresh air needs a correct assumption? Or does it exist a specific classification we should assume for those spaces? 

Thank you very much for your help,

Best regards,
