6 Data Center Economics Have Changed Cost of physical space was a primary consideration in data center design. Cost of power and cooling has risen to prominence. Electrical/mechanical infrastructure makes up 75% of cost of a new datacenter. Data center managers now must prioritize investment in efficient power and cooling systems to lower the total cost of operating (TCO) their facilities.

Detailed analysis would be required to discover actual PUE and costs. Note that due to the Tier 3 requirement for the Enterprise Core area, the chiller plant is retained at full size regardless of the outdoor air economizer and evaporative cooling systems. A system with a smaller chilled water plant would be less sustainable but would save considerable initial cost.
