AVK Vantage is a multi-phase Dublin data centre campus. The first two phases comprise 2no two-story facilities totalling (38,000 m²) and delivering 52 MW of capacity, with space and infrastructure reserved for a future third facility.
Designer Group is delivering the full electrical installation, supporting the campus’s advanced power infrastructure. This includes an on-site 100 MVA multi-fuel generation plant with 11 × 10 MW reciprocating engines and a 10 MW battery energy storage system. The plant primarily uses renewable hydrotreated vegetable oil (HVO), supported by high-pressure gas from Gas Networks Ireland. Multiple diverse power feeds, 400 V electrical systems, and N+1 redundancy ensure high reliability and optimal efficiency, capable of supplying 300 W/SF (3.23 kW/m²) for high-density applications.
The campus emphasises sustainability and efficiency, combining renewable energy use, power purchase agreements (PPAs), and hyper-efficient cooling with outside-air economisation and minimal water usage. Designer Group’s installation underpins Vantage’s commitment to low-carbon, energy-efficient operations while delivering world-class uptime. AVK Vantage sets a new benchmark for resilient, sustainable data centres in Ireland, integrating cutting-edge electrical infrastructure with environmentally responsible design.

Designer Group successfully delivered a cutting-edge, secure data centre facility at the Backweston campus in County Kildare. Designer Group completed the works on schedule, demonstrating its expertise in complex mechanical and electrical infrastructure.
The project involved a full Mechanical and Electrical fit-out of the data halls within a three-storey building. The scope included a complete internal and external package, covering the main entrance and reception, modern offices, meeting rooms, support areas, tea stations, ablution facilities, storage zones, and designated plant areas. Key infrastructure included an ESB substation, client medium voltage (MV) rooms, transformer rooms, fibre meet-me rooms, and network fibre rooms — all designed and installed to exacting standards.
A distinctive feature of the facility is its third block, located at the rear of the main data hall. This comprises an external two-storey plant structure with stairways and intermediate-level walkways, visually enhanced with a metal mesh screen. Two internal, two-storey flat-roof plant rooms connected directly to the central data hall, optimising operational efficiency and space utilisation.
VIE02 is a 9.6 MW data centre located in Vienna, strategically positioned between the airport and the city. The campus follows modular principles, enabling scalable and efficient expansion to accommodate future enterprise growth. Its sustainable design allows rapid deployment of additional buildings while maintaining high operational efficiency, energy performance, and reliability. Designer Group’s scope ensured seamless integration with existing infrastructure, supporting the client’s requirements for flexibility, resilience, and operational excellence.
Designer Group delivered the full mechanical and electrical installation, including connection to the existing campus, along with comprehensive testing and commissioning. The project was based on a modular design provided by a Hyperscale client and included the management and installation of Owner-Furnished, Contractor-Installed (OFCI) systems, utilising prefabrication to streamline delivery and ensure quality.
By combining prefabrication, OFCI management, and rigorous testing and commissioning, VIE02 demonstrates a repeatable, future-proof model for hyperscale and large enterprise data centres. The project highlights the potential for rapid, sustainable growth in high-density data centre environments, delivering both efficiency and reliability while supporting long-term scalability.
Designer Group successfully delivered multiple phases across two data centre campuses in Norway, marking a significant milestone in its European data centre portfolio. With a combined capacity of 56MW, these state-of-the-art facilities demonstrate Designer Group’s capability to deliver large-scale, high-performance infrastructure. The projects were executed by our specialist European Data Centre team, ensuring consistent, high-quality delivery across all phases through coordinated, multidisciplinary execution.
Sustainability and performance were central to the design and delivery. Powered entirely by 100% renewable energy, the campuses leverage Norway’s natural climate to optimise efficiency, incorporating snowmelt technology and rainwater harvesting to support cooling systems. A Power Usage Effectiveness (PUE) of 1.12 was achieved, supported by advanced biofuel solutions for backup generation, aligning with global sustainability standards.
Scope included OFCI equipment design, management, installation and commissioning, alongside full mechanical and electrical installations. Modular design principles and prefabrication were utilised to enhance programme certainty, quality, and safety. Designer Group also delivered Stage 3 design across civil, architectural, and building services, reinforcing its capability to deliver scalable, efficient, and technically complex data centre infrastructure across Europe.
Designer Group successfully replaced the sprinkler system in a fully operational data centre with zero downtime or disruption. The works involved safely removing the legacy system, installing and commissioning the new sprinkler infrastructure, and erecting scaffolding above the live data hall, all carried out under strict safety protocols.
Designer Group managed the N₂ generator system, performing corrosion testing, proposing upgrades, and installing a nitrogen generator compressor to ensure continuous operational safety and compliance.
The project demonstrates Designer Group’s expertise in delivering complex retrofits in live, high-security environments while maintaining uninterrupted operations. Through meticulous planning, rigorous safety measures, and coordinated installation, the team ensured a seamless transition to the new sprinkler system, enhancing fire protection and operational reliability for the data centre.
STO 01A involved the full fit-out of two 3 MW data halls within a live, fully operational data centre, including electrical, mechanical, structural, and architectural services. Designer Group delivered critical plant and infrastructure installations while ensuring zero disruption to ongoing operations.
The scope included civil, structural, and architectural works, as well as comprehensive mechanical and electrical installations. Designer Group managed the design, installation, and commissioning of Owner-Furnished, Contractor-Installed (OFCI) equipment, while also delivering end-user rack installation and hot aisle containment systems. Stage 4 and 5 design development ensured that all systems were fully coordinated, integrated, and optimized for operational efficiency and reliability.
A key focus of the project was the seamless integration of new infrastructure with existing live and critical services. By combining meticulous planning, staged installation, and rigorous testing and commissioning, Designer Group successfully delivered a high-performance data hall environment capable of supporting demanding enterprise workloads.
