The assesment process is designed to minimize the impact on your operations, with a significant proportion of the effort being conducted remotely at a pace which suits your requirements.


Typically, the process may take between two and three months of lapsed time to complete from assesment initiation to generation of the report, recommendations for further improvement and certification.

The certification period is two years after which an updated assesment and renewal of certification may be conducted.

In order to support on-going performance improvement arising from the recommendations, a remote interim assesment is conducted one year after the certification date. This enables the impact of implemented recommendations and of changes in operations, services and infrastrcuture to be evaluated and further recommendations given.


CEEDA uses energy efficiency frameworks which are tailored to meet specific environmental, infrastructural and operational requirements of Enterprise-, Colo- and Telco-class data centers, for both existing facilities and new builds. These frameworks are composed of best practices, standards and metrics from ASHRAE, Energy Star, ETSI, EUCoC, ITU, The Green Grid and selected ISOs.



The assesment comprises a cumulative graded framework of these practice criteria. For compliant facilities, the resulting certification award may be made at ascending levels of Bronze, Silver and Gold. The assesment is a cumulative process: to attain Silver, the data center must be sufficiently compliant at Bronze level. To attain Gold, the data center must be sufficiently compliant at both Bronze and Silver levels. The table below shows a representation set of assesment criteria:

  • Integrated IT, Service Provision, M&E teams

  • Modular UPS

The assessment process produces a compliance profile across up to 80 best practices and metrics. The resulting gap analysis is used for generating sets of recommendations for performance and harmonization across all data center disciplines.


The value of the CAPEX and labor costs and potential impact on OPEX reduction are estimated and assigned to each of the recommendations. These may then be scheduled to optimized the deployment of CAPEX and labor, according to the specific requirements of each data center.


Additional tools are supplied to enable the mapping of functional areas – such as: cooling, power, monitoring, IT services and hardwire – against best practice criteria and to enable the recording of the impact of a program of work against changes in infrastructure, operations and the corresponding best practices criteria.


The impact of the execution of recommendations is assessed one year after the certification date. In tandem, key performance metrics which represent control points for energy efficiency are authenticated, enabling tracking of performance and comparisons across the data center estate.
