The recipe for data centre design has changed! What are the right ingredients, and will our clients accept the final dish? The pace of change in the data centre sector, both inside and outside the rack, is astounding. With densities exceeding 150 kW per rack and campuses over 1 GW, how can we blend today’s regulatory and engineering demands with the needs of tomorrow? This presentation delves into the policies the UK government hopes will enable the data centre sector to thrive while maintaining our net zero commitments. We will explore the latest standards and regulations, including the UK Net Zero Building Standard, EEDs, LEED, BREEAM, and other influences shaping data centre design in the UK and Europe.
