I don't understand how designing a datacenter is a sysadmin et al task. We may have input to the requirements phase, some oversight of the design but we wouldn't really design the building.
Building design is a complex subject, in the UK architects study for at least 5 years before they get their degree and 2 years post graduate before they can call themselves architects.
It's an interesting subject but it's not our job and should be left to professionals in the field.
