Unless a service room contains electrical equipment required to be in a rated room as detailed in CSA C22.1, “Canadian Electrical Code, Part I,” then a server room by NBCC 2015 is not required to be in a rated room. Now it may be preferable to locate a server room in a rated enclosure but I'm only talking about the NBCC requirements. So unless there are life safety systems located in that room then no rating would be required.... a server room by NBCC 2015 requires no FR right?
