different power capacities, configurations and integration with existing systems. This allows a pay-as-you-grow approach and data centres can quickly expand their capacity by adding more prefabricated modules as the demand grows. Such designs can then be deployed at a large scale (high volume of modules). When it comes to larger scale data centres of
10MW – 100MW, the prevailing construction methodology utilises prefabricated building blocks: power modules / skids typically include medium and low voltage switchboards, transformers, uninterruptible power supplies (UPS) and batteries, as well as cooling units for heat management. In this case the individual building block size is limited and defined by transformer / generator size. Typical sizes are2–3MW, so for example, a 40MW data centre can be powered by 5 x (4+1) 2MW Power module topology.
PFMs and carbon footprint Nearly all operators will consider the role of prefabrication in reducing carbon footprint and supporting the circular economy. Modular buildings and equipment can be easily dismantled and repurposed, promoting resource efficiency based on the principles of reducing, reusing and recycling. As a construction material, steel has a lower
carbon footprint in comparison to concrete, and further benefits can be achieved by utilising mass timber. Beyond its environmental benefits, wood introduces a distinctive aesthetic appeal to data
centre design. The warm and natural characteristics of wood create inviting and visually appealing spaces. In an industry where functionality often takes precedence over aesthetics, the introduction of wood as a primary material helps facilities to fit seamlessly with their surroundings. The controlled, offsite manufacturing process
also helps reduce the impact on the environment. It leads to reduced construction waste in comparison to traditional construction methods and optimised resource use and efficiency. And as many prefabricated providers have multiple manufacturing locations, PFMs can help reduce
the carbon footprint associated with transportation by manufacturing in a geographically closest location.
An adapting industry As the data centre industry continues to evolve and adapt to the growing demand for high performance computing and the need for more capacity at speed, PFMs are a compelling solution. By embracing modular components and building blocks, the industry can achieve uniformity in design and infrastructure but also optimise resource use, leading to cost savings and improved operational efficiency.
