Brennen covered most of this but I can add a few more things…
The I.T. room is located in the middle of the building. Colorado is very cold during winter, Why not take advantage of this?
Our cooling demands aren’t that extreme. We just don’t need that many servers to run the business. An elaborate exterior water cooling system would be far more expensive than the simple rooftop HVAC unit we have spec’d. Also it’s advantageous to have the data center in the central part of the building because all network drops terminate there and it needs to be the most secure room in the whole building (proximity to an exterior wall increases risk somewhat).
Also no mention of any fun removable flooring in the I.T. room.
Expensive and unnecessary. We’ll have a high dropped ceiling with ladder rack for crown molding. If all cabling goes up there’s no need to raise the floor.
All that roof space and not a single skylight in the building plans.
The plans in the blog post are not exhaustive. There are many, many skylights spec’d out for this building and natural light is the default lighting system in most rooms.
I see no mention of any emergency power cut buttons or switches in the I.T. room or production area…
Again, the plans linked are not exhaustive. An electrical system for a building of this scale is complex and emergency cutoffs are carefully planned alongside circuit divisions and wiring setups. In general: if you don’t see it in the plans linked that doesn’t mean it won’t be in the building.
