DCEP study guide
DCEP · Work through your exam, one topic at a time.
The Data Center Energy Practitioner (DCEP) Program is a professional credential for people who assess and improve energy performance in data centers - energy managers, facilities and mechanical engineers, commissioning agents, and efficiency consultants. This independent study page is built around five practice domains: data center energy efficiency assessment; IT equipment and workload management; cooling systems and airflow management; electrical power distribution and efficiency; and energy metrics, benchmarking, and reporting. Each domain is weighted evenly here because the program's official domain weights could not be confirmed. Coverage emphasizes the practical judgment an assessor needs: scoping an assessment, interpreting nameplate and measured load data, evaluating airflow and cooling configurations, tracing electrical losses from utility service to the rack, and turning measurements into defensible metrics and reports. The DCEP study guide has 5 sections and about 1,619 words.
01Data Center Energy Efficiency Assessment
An efficiency assessment starts with a boundary decision. Before any number is calculated, you must know what is inside the fence: IT load only, or IT plus cooling, UPS losses, lighting, and office space.
349 words, about 2 min02IT Equipment and Workload Management
This domain covers how IT decisions - hardware selection, utilization, virtualization, and workload placement - translate into facility energy. The examiner wants you to connect server-level behavior to data center-level metrics.
347 words, about 2 min03Cooling Systems and Airflow Management
Cooling is where most efficiency opportunity lives. Questions test your grasp of airflow physics, containment, setpoints, and the trade-offs between air- and liquid-based approaches.
324 words, about 2 min04Electrical Power Distribution and Efficiency
This domain covers the path from utility to server and the losses along it: transformers, switchgear, UPS systems, PDUs, and busway. Core concepts: The distribution chain : utility transformer, main switchgear, UPS, PDU, rack PDU, server power supply.
312 words, about 2 min05Energy Metrics, Benchmarking, and Reporting
This domain is about measurement discipline: choosing the right metric, computing it correctly, and reporting it without misleading the reader. Core concepts: PUE = total facility energy / IT energy.
