Methodology

Data centre cost index methodology

To generate the results of our Data centre cost index 2022, data centre benchmarking cost data was captured from more than 200 live or recent projects in more than 20 countries.

Cost data is captured under the following key capital cost headings: shell & core, architectural fit-out and finishes, mechanical and electrical fit-out, general contractor preliminaries, general contractor margin, general contractor contingency, mechanical and electrical equipment.

All costs are converted into a single currency, in this case USD, using the foreign exchange rates advised by our economists.

Exchange rates

We used the FX rate on 01/10/2022 for the conversions to USD. 2022 has seen extreme fluctuations between USD and other currencies. In particular, index results for some EMEA markets should be referenced with caution and adjusted as required.

Baseline model assumptions

Benchmarking cost data modified to represent a typical build-to-suit hyperscale data centre in the range of 8-32MW. Multi-client colocation facilities or enterprise end user facilities may change the indicated $/W by up to 15 percent.

Shell and core

Our network of regional offices provided real project benchmark data for actual data centre shell and core construction expenses, where available.

Equipment

Actual quoted equipment costs have been applied and factored in as necessary. Additional costs per location are also applied for local sales tax/VAT, import duties and freight where applicable.

Construction labour and materials

The index results incorporate actual construction labour and material costs from live or recent projects in each market.

Preliminaries/general conditions and general requirements

The index results incorporate actual preliminaries/general conditions and general requirement costs from live or recent projects in each market.

Exclusions

The cost model does not include any client direct costs, land purchase costs, utility works, groundworks, site works, active IT equipment, fibre cabling to support office fit-outs or professional services fees.

Online data centre survey

In September 2022, we ran an online survey to gauge the views of data centre sector players on industry trends. We received a total of 245 responses. Our respondents were based in/responsible for the following regions:
