Maximizing Data Center Performance: The Critical Stages of Commissioning

In today’s era of unrelenting digital demand, having a fully operational data center is crucial for ongoing success. As the landscape changes and these facilities grow in complexity and importance, the commissioning process has become a critical factor in ensuring their reliability, efficiency and performance. At JLL, we've seen firsthand how a well-executed commissioning strategy can make the difference between a data center that only meets basic operational requirements and one that achieves maximum performance and efficiency.

Commissioning is more than a final checkbox in the construction process; it's a comprehensive quality assurance approach that should be integrated from the earliest stages of a project through to operational handover. But to truly put your project on a path to success, it’s essential to understand how the key stages of commissioning contribute to optimal performance.

Programming, design and early testing: laying the foundation for success

The commissioning process begins long before the first piece of equipment arrives on site. At JLL, we've found that integrating commissioning expertise from the earliest stages yields significant benefits. This process encompasses three crucial phases: programming and design, factory acceptance, and site acceptance testing.

During programming and design, workshops with owners help define key performance metrics. This results in a formal document that guides the entire project team, ensuring alignment on critical factors like redundancy, reliability, and sustainability. Commissioning experts participate in design reviews, often uncovering opportunities to improve system coordination and equipment accessibility that can significantly reduce future maintenance challenges and operational costs.

As the process moves into factory and site acceptance testing, the focus shifts to quality assurance. Factory acceptance tests allow identification and resolution of issues before equipment leaves the manufacturer, potentially saving weeks or even months in the project timeline. Once equipment arrives on site, rigorous inspections and static testing verify functionality and performance of critical components.

Insider tip: Develop a comprehensive document repository early in the process. This centralized information hub, containing everything from owner requirements to equipment specifications, becomes an invaluable resource throughout the commissioning process and into operations. Also, involving a provider with facility management knowledge ensures operational requirements are addressed early, potentially saving time and resources later.

Start-up and functional performance testing: bringing systems to life

As we progress through the commissioning process, the focus shifts from individual components to system-level performance. This stage encompasses start-up, pre-functional testing, and functional performance testing.

During start-up and pre-functional testing, each piece of equipment is checked for basic functionality. This includes mechanical checks like starting and stopping equipment, as well as electrical checks such as verifying proper voltage and phase rotation.

Functional performance testing takes this a step further, verifying that each system meets its specified sequence of operation and rated performance under various conditions. Comprehensive test procedures that simulate live conditions and potential failure scenarios are developed, ensuring all stakeholders review and sign off before testing begins.

Insider tip: Involve your facility management team in functional performance testing. This provides invaluable hands-on training, ensuring your operations team is familiar with the systems before taking control. We've seen this approach significantly streamline the transition to operations.

Integrated systems testing and transition to operations: ensuring long-term success

The final stages of commissioning are where the true value of a comprehensive approach becomes evident. Integrated systems testing validates that all systems work together seamlessly, performing at both minimal and full rated capacities under various failure modes.

A comprehensive load bank plan brings the facility up to its rated capacity, ensuring that mechanical and electrical equipment can perform under full load and meet service level agreements. A site-wide “pull-the-plug” test provides invaluable data on how the entire infrastructure responds to a utility failure, often revealing nuances in system interactions that can be optimized for better resilience.

As the transition to operations begins, all the knowledge gained throughout the commissioning process is compiled into a comprehensive system manual. This includes not just equipment specifications, but also lessons learned during commissioning and recommendations for ongoing operations.

Insider tip: It’s definitely worth conducting a thorough lessons-learned session with all key stakeholders at the end of the commissioning process. This not only helps improve future projects but also provides valuable insights for the operations team as they take over the facility.

The path to data center excellence

As data centers continue to grow in complexity and importance, a robust commissioning process is no longer optional – it's essential. By integrating commissioning expertise from the earliest stages of a project through to operational handover, data center owners and operators can significantly enhance the reliability, efficiency, and performance of their facilities.

At JLL, we believe that commissioning is not just about ticking boxes; it's about laying the foundation for operational excellence. By focusing on these critical stages and implementing best practices, data centers can be built to exceed specifications and stand fully prepared to meet the demands of our digital future.
