The future of data centres: Speed, sustainability, and AI-readiness at scale
This article was written by Leona Lo, EITN’s editor-at-large Asia Pacific’s data centre landscape is undergoing a major shift. As AI workloads grow heavier and deployment timelines tighten, operators are also facing mounting pressure to meet sustainability targets. At Siemens’ Data Center Industry Analyst Day on 17 Jul 2025, leaders from WT Partnership, Red Engineering, and Exyte shared their views on how the market is evolving—and what it takes to build smarter, safer, and more resilient infrastructure in today’s climate. Asia’s data surge and the rise of modular construction “Asia is home to nearly 60% of the global population— an enormous market to serve,” said Jodi Pieterse, Director at WT Partnership. “We’ve seen massive digitalization in the region, and data center builds now regularly exceed 40–50 megawatts, increasing in capacity year-on-year. In Thailand alone, we’re seeing multiple data centre developments exceeding 200-plus megawatts in total capacity.” Pieterse noted that traditional procurement and construction models are being re-evaluated. “Project developers used to focus on getting the best value through competitive tenders. But today, due to supply chain constraints, they are being forced to engage directly — often single source — with key vendors to secure resources. He added that pre-fabricated and modular designs— once considered untested —are rapidly gaining ground in Thailand. “This shift is being driven by a shortage of skilled labor and the need to reduce build times. As the market matures, we’re also starting to see cost efficiencies emerge.” Design bottlenecks and hardware limitations Joe Ong, Technical Director at Red Engineering, highlighted how the design process is under pressure. “For any data centre project in a design phase, critical decisions are made in the initial weeks. There is no luxury of time at all.” He spoke of the challenge in building up design talent. “Data centre design and delivery requires deep technical skills and knowledge that cut across multiple disciplines of architecture, structure, electrical, mechanical, plumbing, fire protection, info-communications technology, and construction methodologies. It takes a minimum of three to five years for any graduate data centre engineer to acquire a reasonable level of competency to contribute independently in just one design discipline. The runway is long, challenging but undoubtedly, a very rewarding journey for the engineer.” Ong also addressed concerns about infrastructure planning, particularly when designing for AI workloads. “For an AI data centre, more often than not, end users typically require data centre mechanical and electrical infrastructure to be built on the basis that the entire data halls are completely filled with only AI high-density compute racks, which have a very high power draw. However, in reality, only an estimated 60–65% of the total rack count in an AI data centre comprises AI high-density compute racks. The remaining racks are networking, storage, and normal compute, which have a significantly lower power draw. This gives rise to an inconvenient truth: there will be a marked difference between the provisioned capacities of mechanical and electrical infrastructure versus actual demand when in operations.” To reduce time to market, he said, clients are increasingly exploring edge and containerised solutions. “We need to carefully watch the industry through the lens of global leaders of the community such as Nvidia and OpenCompute Project (OCP). In future AI data centres, it is anticipated that multiples of compute capacity will be compressed into the same rack space, driving up demand for power and cooling. White space will shrink; grey spaces for mechanical and electrical infrastructure will expand. Ultimately, the roof of any data centre will be the limit, because the roof will limit how many cooling towers may be installed for heat rejection.” Engineering for speed and sustainability Joshua Hunt, Exyte’s Director of Design & Engineering, described how prefabrication and parallel construction are gaining momentum. “If you can pre-fabricate and test modules offsite while the shell is being built, you’re saving months. That’s the future—though the re-engineering cycles can add extra time that isn’t always in the project schedules.” Exyte is also looking ahead to new technologies. “Cryogenic cooling, LNG-supplied cooling, quantum computing readiness—these are becoming mainstream design conversations.” Rethinking data centres for the AI Age Data centres in Asia Pacific are no longer just about uptime. They must be flexible, efficient, and built to meet growing expectations around environmental and operational accountability. The region’s varying regulations, workforce limitations, and infrastructure gaps add layers of complexity. “Successful data centre project delivery is now more than ever about rethinking everything from supply chain to operations,” Pieterse said. As demand continues to grow, partners like Siemens are helping to enable this next phase with integrated systems that support safety, performance, and sustainability. With modular construction, smarter design, and a growing focus on lifecycle efficiency, the data center of the future is taking shape—faster than ever.
