The Technical Specification for Prefabricated Data Centers has recently been officially released. As one of the drafting organizations, KSTAR participated in the development of the standard. Covering key aspects such as site selection, foundation works, structural design, integration, assembly, and testing, the standard provides an important reference for the industry's advancement toward more efficient and standardized modular development.

As the digital economy continues to expand and applications such as cloud computing and artificial intelligence accelerate their adoption, data center construction is evolving toward greater reliability, efficiency, and faster deployment. Compared to traditional approaches, prefabricated data centers represent the industry's defining direction, driven by three core advantages: modular design, factory pre-integration, and rapid on-site deployment. The standard explicitly applies to new construction, renovation, and expansion of single-layer or multi-layer stacked prefabricated data centers.

Comprehensive Coverage, Deeper Systematization

Rather than focusing on a single product or function, the standard establishes systematic requirements across the full lifecycle of prefabricated data centers. It covers critical areas across the full lifecycle, including structural performance, functional modules, factory integration, on-site assembly, and testing methods. It also clearly defines core modules such as IT modules, power modules, battery modules, cooling modules, cooling source modules, intelligent management modules, and fire protection modules, further underscoring the system-level nature of prefabricated data centers.

Structural Resilience, Rigorous Safety

The standard sets out clear requirements for both structural reliability and operational safety. For example, stacked prefabricated data centers should generally not exceed five stories, with a structural height of no more than 24 meters, while the enclosure protection rating should be at least IP54. For power and battery systems, the standard specifies detailed requirements for grounding, fire suppression, ventilation, and fire protection—critical safeguards for long-term stable operation. It reflecting the industry’s strong emphasis on long-term stable operation and well-defined safety boundaries.

Faster Delivery, Stronger Assurance

The value of prefabricated data centers lies not only in faster deployment, but also in greater control over delivery quality. The standard emphasizes moving more work to the factory stage and requires joint no-load testing and staged load testing after on-site assembly to verify overall delivery performance. This demonstrates that prefabrication is not about simplifying the construction process, but about improving engineering consistency and system reliability through a higher level of integration and verification.

Integrated Strength, Greater Value

The technical framework outlined in the standard makes it clear that the competitiveness of prefabricated data centers is no longer defined by standalone equipment alone. Instead, it increasingly depends on the coordinated capabilities of power, energy storage, cooling, safety, and intelligent management systems. As one of the drafting organizations of the Technical Specification for Prefabricated Data Centers, KSTAR’s participation reflects its long-term commitment to the data center infrastructure sector. Leveraging its expertise in UPS systems, batteries, cooling solutions, and infrastructure integration, KSTAR will continue to provide stronger support for the development of digital infrastructure.

Looking ahead, as demand for computing infrastructure continues to grow, prefabrication, modularization, and integrated deployment are set to become defining trends in data center development. Building on its deep expertise in data center infrastructure, KSTAR will continue to drive product innovation, solution optimization, and industry collaboration, contributing to the high-quality development of digital infrastructure.
