What you describe are not faults they are tradeoffs. Perhaps instead of having 14' ceilings and sub-floors and AC a datacenter would have 6' ceilings and no AC.
Whether the technology makes sense depends on the overall cost effectiveness. Google putting a data center near a river and using the river water in a complex water cooling system, or routing used non-potable water to provide cooling are both systems that are used today and likely have at least as many challenging aspects, yet are in use today b/c they lower overall costs.
