Data centres – key metrics for existing and emerging hubs232TABLE A3Data centre archetypes Data centre archetypes, illustrated in Figure 12, were developed based on 15 global data centre hubs, made up of the 10 largest data centre hubs based on power load and five emerging hubs, as shown in Table A3 below.

The different levels within the framework were designed based on global averages and industry analysis and validated through review and consultation with industry experts. While these archetypes can be used to help inform design choices for cooling technology, there are additional nuances and specifics, including local regulatory requirements, that must be accounted for that are not included in this framework.
