Five Steps to Becoming an “Energy-Efficient Data Center”

Step 1: The Efficiency Check

  • Data collection in an on-site visit
  • Preliminary assessment

Step 2: Assessment and Analysis of Potential Savings

  • Measurements, including energy consumption, air conditioning, and airflow (in the data center only)
  • Assessment with analysis of the current state
  • Target definition and optimization strategy
  • Development of scenarios and list of measures

Step 3: Planning and Cost/Benefit Analysis

  • Plan for implementing the proposed savings measures that were approved
  • Economic analysis of the measures planned

Step 4: Technical Implementation

Step 5: Certification

  • Evaluation of target achievement based on your specific list of criteria

Certification at a Glance: From Analysis to Certification

Our experts analyze the energy streams used in your data center, including: air-conditioning, power supply, IT environment, lighting, access security, and fire protection.

Our analysis covers all areas, including management and the quality assurance system you use. We then assess your energy efficiency using TÜV Rheinland’s list of criteria for data centers. The list includes questions on systems, installations, and equipment that significantly impact energy consumption. We weigh the importance of each of these topics while incorporating them in the overall evaluation of energy efficiency. “Energy-efficient data center” certificates are issued to businesses that satisfy at least 60% of the criteria in the overall energy analysis.
