From Project Management to the Future of Data Centres: A Conversation with Ventac’s Data Centre Project Manager Eoin O’Sullivan

Eoin O’Sullivan, Data Centre Project Manager at Ventac, brings his experience into one of the fastest-growing and most critical sectors globally – data centres. We sat down with Eoin to talk through his journey, the evolution of the industry and what really matters when it comes to delivering resilient, future-ready data centre infrastructure.

From home to high-tech manufacturing

Eoin’s path into engineering started in Tipperary, followed by studies at the University of Limerick, where he graduated in 2004 with a degree in Information Technology and Telecommunications, a hybrid of computer and electronic engineering. Shortly after, he joined Intel where he would spend 18 years progressing through technical and engineering roles.

“I started as an equipment technician, then moved into process engineering and later install and de-install projects in the fab,” he explains. That final role gave him exposure to the full complexity of semiconductor manufacturing environments. A “fab” (short for fabrication facility) is where raw silicon is transformed into computer chips. It’s an ecosystem of tightly controlled processes involving electronics, gases, power systems, plumbing and ultra-precise environmental conditions. “I was working across all of it. Anything that keeps a fab running, I was involved in that,” he says.

Why move into data centres?

After 18 years in semiconductors, Eoin was ready for change. “I didn’t want to stay in the semiconductor industry, but I still wanted to be in technology,” he says. “Data centres were the natural next step. They were at the time, and still are, one of the fastest-growing sectors.”

Like many transitioning into the space, he invested in upskilling before making the move. He completed a series of data centre-specific certifications, including CDCP and CDCS (Certified Data Centre Professional and Specialist), along with cloud computing training inspired by Amazon systems and a Cisco networking course. “I wanted a full view of how data centres operate, from infrastructure to cloud to networking,” he says. Shortly after, he joined Ventac.

Building structure before building projects

At Ventac, Eoin stepped into a role that is as strategic as it is technical –  Data Centre Project Manager. One of his first responsibilities was not with delivering projects but rather everything to do with enabling them.

“We didn’t have a formal project management office or process in place,” he explains. “So, my first job has been building that.”

Rather than imposing rigid frameworks, his approach is gradual integration. “The advantage is I’m not working against previously installed systems. I can design a process and bring it in step by step.”

Alongside this, he supports wider Ventac projects across industries, helping teams’ structure and control delivery more effectively, from automotive work to R&D collaborations, including sustainability-focused initiatives in partnership with academic institutions.

The data centre industry: from infrastructure to everyday life

One of the most striking shifts Eoin has observed is how embedded data centres have become in everyday living.

“People don’t realise it, but from the moment you wake up to the moment you go to bed, data centres are involved in everything; banking, phones, smart devices, even wearables,” he says.

“It’s not that they control life, but they underpin it.” This dependency brings with it significant challenges.

The biggest challenges: capacity and supply chains

According to Eoin, the industry is facing two dominant constraints:

1. Capacity
Demand is growing exponentially, driven by cloud computing, AI and digital services. But infrastructure, particularly power, is struggling to keep up the pace.

“You can’t build enough of anything right now. Data requires power, and power is always the limiting factor.”

2. Supply chains
From chillers and AHUs to skilled labour, every component of data centre construction is under pressure. “It’s not just materials. It’s people; skilled engineers, installers, operators – everything is stretched.”

These challenges are global, not regional, and are shaping how operators design and build future facilities.

Opportunity: renewables and self-sufficiency

Where there are constraints, there are also opportunities. A major shift in the sector is the move towards renewable energy and energy independence, driven by regulation and operational requirements. In Europe and Ireland in particular, data centre operators are increasingly required to integrate renewable sources and demonstrate sustainability performance.

There’s a clear shift toward energy self-sufficiency,” Eoin says. “Whether through microgrids combining renewables and battery storage, or emerging technologies like Small Modular Reactors (SMRs), the direction of travel is undeniable.”

He also highlights emerging innovation in waste energy reuse, particularly in the Nordics, where data centre waste heat is increasingly integrated into district heating systems for nearby residential developments. Data centres are no longer just digital infrastructure—they are becoming active contributors to local energy ecosystems, especially in dense urban environments.

Noise: the overlooked infrastructure challenge

While energy dominates most industry conversations, Eoin is clear that acoustics are becoming increasingly critical. “The main source of noise in data centres is cooling systems; air handling units, chillers, mechanical plant,” he explains. “As facilities move closer to urban and residential areas, noise is no longer just an operational concern. It’s a regulatory and community issue.

“You can still have birds, wildlife, people living nearby. If a facility is producing over 100 decibels, that matters.”

For Ventac, this is where expertise becomes critical. Emphasising the importance of early acoustic solution integration, Eoin says, “Noise control should be designed in from the start. If you wait until after construction, you’re always compromising.”

Designing earlier, building smarter

One of Eoin’s strongest messages is the importance of early-stage involvement. “The sooner you’re in the design phase, the better the outcome. It reduces cost, avoids retrofits and prevents problems later.”

This aligns with Ventac’s approach of embedding acoustic and engineering input early in client design teams where infrastructure decisions must meet extremely tight compliance and performance standards.

“If it’s not compliant, nobody wins. Not the OEM, not the operator, not us.”

Compliance, precision, and no second chances

In Eoin’s view, data centres are among the most highly regulated environments in the world.

“Everything has to be right. From certification to specifications to compliance. There are no second chances.”

This is especially true when working within global supply chains where multiple stakeholders must align.

“Ultimately, you’re working for the client, but also for their clients. If one link fails, the entire chain is affected.”

The future: batteries, materials, and smarter energy systems

Looking ahead, Eoin sees innovation accelerating in three key areas:

• Renewable integration and on-site generation
• Battery storage systems
• Thermal and material innovation, including phase change materials

Thinking on Ventac’s product development for electric vehicles, particularly the Battery Wrap, and applying this R&D approach to data centres, Eoin notes: “If you can extend battery life across thousands of units, the impact is significant—not just in terms of cost savings, but also reduced environmental footprint and enhanced safety,”

Major Trends and Shifts

While several themes emerged throughout the conversation, one trend stood out clearly – the shift towards modularisation in data centre design and delivery. From Eoin’s perspective, this is being driven directly by real-world constraints. “From talking to clients and visiting roadshows, the biggest trend is towards modularisation,” he explains. “They see it as the most effective way to construct and scale data centres globally. Rather than building large, single-phase facilities, operators are increasingly adopting a modular approach, manufacturing components off-site and assembling them on-site or delivering them as pre-engineered units.” This approach enables faster deployment, improved quality control, and greater flexibility. It also aligns with one of the industry’s biggest challenges, which is power availability.

“As power becomes available, you can scale accordingly,” Eoin says. “You’re not waiting for one large data hall to come online. You can build in phases and start operating much sooner.”

This shift is not limited to any one region. It is a global trend, driven by the need for speed, efficiency and resilience in an increasingly constrained environment. For Ventac, it also represents an opportunity to collaborate more closely with OEMs, developing bespoke acoustic solutions that integrate seamlessly into modular systems, supporting clients as they scale smarter, faster and more efficiently.

Collaboration is key

Despite the technical complexity of his role, Eoin returns repeatedly to one simple principle: relationships matter.

“Site visits are essential. You can’t manage projects from behind a desk. Meeting operators, contractors, and site teams early helps build trust and ensures smoother delivery.

“It’s about knowing who to call when you need something. That only happens when you’ve been on site.”

Final thoughts: building what comes next

For Eoin, joining Ventac is not just a career move. It’s an opportunity to shape systems in an industry that is still rapidly evolving.

“I wanted to work in a fast-growing sector, on critical infrastructure, with strong support around me. And I wanted the chance to travel and work on meaningful projects.”

As data centres continue to expand in scale and complexity, project managers like Eoin sit at the crossroads of engineering, sustainability and operational reality. His journey so far demonstrates that the future of data centres isn’t just about capacity or computing power, but about designing infrastructure that works better for the people, places, and systems that depend on it. Or as Eoin puts it more simply: “If you get the design right from the start, everything else becomes easier.”
