Data Centres are the beating heart of a business and a global economy. But as workloads grow denser, driven by AI, analytics, and high-performance computing, CFOs face a critical question, Do we retrofit our existing facility or invest in a new build?
This question isn’t just based on technical input but also financial, strategic, and future-focused.
The Retrofit Route
Retrofitting can feel like the pragmatic choice. Why build from scratch when you already have the base infrastructure in place? Upgrades to the Mechanical and Electrical infrastructure, cooling systems, power distribution, and rack layouts can extend the life of your facility. For CFOs, this means:
- Lower upfront costs compared to greenfield projects.
- Faster deployment, avoiding long construction timelines.
- Deferred capital expenditure, freeing funds for other priorities.
But retrofits come with caveats. Older facilities often struggle with scalability bottlenecks. Traditional air-cooling systems weren’t designed for today’s high-density racks, leading to hot spots, uneven airflow, and increased maintenance costs. Over time, these inefficiencies can erode the savings you hoped to achieve.
The New Build Advantage
A new build offers a clean slate. Modern designs integrate liquid cooling, modular power systems, and energy-efficient layouts from day one. For CFOs, the benefits include:
- Predictable operating costs thanks to optimised energy use.
- Compliance confidence, meeting AS/NZS 3666, Uptime Institute, and ASHRAE standards without retroactive fixes.
- Long-term ROI, as the facility supports next-gen workloads without costly mid-life upgrades.
Yes, the initial capital outlay is higher but consider the total cost of ownership (TCO). A purpose-built Data Centre reduces risk, enhances reliability, and positions your organisation for growth in an AI-driven world.
The CFO Lens
This isn’t just about bricks and mortar, it’s about aligning IT strategy with business goals.
There are many questions that need to be asked, a few to start with –
- What’s the projected workload growth over 5–10 years, direct this to your IT team?
- How do compliance and sustainability targets influence design – to the Compliance and Sustainability Manager?
- Can retrofitting deliver the same resilience as a new build – ask your engaged Designers?
Bottom Line
Retrofit if speed and short-term savings matter most. Build new if you’re chasing scalability, efficiency, and future readiness. Neither of these questions can be answered without fully engaging and understanding the Technology Roadmap. With Technology footprints changing at lightning speed these days, expect the 5-to-10-year part of the projection to be very loose on the details. Either way, partner with experts who understand both the technical (IT and Facility) and financial dimensions of Data Centre transformations.
At BARM DC, we help organisations make these decisions with clarity and confidence, because in the world of high-density workloads, the right choice today shapes your success tomorrow.
This BARMDC thought leadership piece explains why retrofit offers lower upfront costs and faster deployment but can struggle with scalability and efficiency, while a new build provides future-proof design, predictable operating costs, and long-term ROI. CFOs should weigh short-term savings against total cost of ownership to align IT strategy with business growth. (www.barmdc.com)
