Sustainable Data Center
SDC is High Knowledge GmbH’s certification system for the structured assessment of data centres. Its 301 criteria in 11 categories combine energy and resource efficiency with technology, organisation and operations. The outcome is a documented assessment of the specific data centre, with a rating from A to G.
301 criteria. A transparent result.
A capable data centre needs more than a single efficiency metric. Sustainable Data Center examines the relationships between infrastructure, energy, resources, management and day-to-day operations.
The SDC catalogue v3.0 comprises 11 categories, 46 criteria groups and 301 criteria. Assessments are based on defined requirements and traceable evidence. Document reviews, on-site audits and individual criteria assessments are brought together in an audit report.
The certificate identifies the assessed data centre, its rating from A to G, the catalogue version, certificate number and validity period. This makes the scope of the assessment clear. A certificate for one site does not make a blanket statement about every product or the entire company.
From assessment to certification
1. Define the scope. Together, we clarify the site, system boundaries, available evidence and the appropriate assessment model. High Knowledge owns and licenses the SDC system. Depending on the agreed model, the certificate is issued by High Knowledge or an assessment partner.
2. Review evidence and audit on site. Qualified auditors assess the data centre against the SDC catalogue. Findings, evidence and outstanding issues are documented. The programme rules govern impartiality and the management of conflicts of interest.
3. Assess the results and issue the certificate. The certification decision is based on documented assessment results. The site-specific certificate states the achieved rating and the applicable catalogue.
4. Track progress. The three-year certification cycle includes the initial assessment, annual surveillance and recertification. Changes to the data centre and relevant operational metrics are taken into account.
Assess thoroughly. Communicate precisely.
The SDC programme rules v3.0 define how certificates and marks may be used. Certification statements must refer to the assessed data centre and be traceable through the rating, catalogue version and certificate number. They do not automatically substantiate claims of climate neutrality.
For use of the SDC mark in consumer communications, the programme rules provide for independent third-party monitoring. Requirements covering use of the mark, complaints, appeals, suspension and withdrawal form part of the system.
SDC and technical standards: SDC complements technical assessments against DIN EN 50600 and ISO/IEC 22237 with a structured evaluation of energy, resources and other operational aspects. The specific standards, system boundaries and evidence to be assessed are expressly agreed for each engagement.
NIS2 and operational resilience: Evidence concerning infrastructure and operations can support elements of risk management. Full fulfilment of applicable NIS2 obligations, including incident reporting and organisation-wide security measures, requires a separate assessment.
