Thank you team.. I think we have this one closed out.
The is an enclosed water purification system. The 'building' is a lightweight steel enclosure (very little insulation, if any). Non-occupied space.
Site is a petroleum facility in Texas, so not many AHJs around.. but we do have peer-review...
We have process skids and server areas that are in small, pre-fab buildings with simple HVAC.
The vendors are sizing conductors and servers based on the HVAC operating correctly. If HVAC fails then conductors will be undersized (overheat), servers and UPS may trip off, etc.
It's standard...
