ENERGY EFFICIENT DATA CENTRES
NTRE’S FIRST FFICIENCY
matches the solar array, backed up with a 20-year warranty to help marry up the two timelines. Additionally, silicone retains its flexibility. It can withstand the thermal movement and mechanical stress exerted by heavy racking systems as they expand and contract throughout the day. By aligning the lifespan of the roof with the lifespan of the energy generation assets, operators can secure a long-term, low-maintenance energy strategy.
THE ‘BELT AND BRACES’ APPROACH While energy efficiency is the headline, we cannot ignore the fundamental role of the roof: keeping water out. Water is the single biggest physical threat to a data centre. Many facilities rely on sheet-applied
membranes or metal roofs. These systems are reliant on seams, joints, and fasteners, which all feature potential failure points that can open up due to thermal expansion or vibration. Liquid-applied silicone eliminates these weak
points. It cures into a single, seamless rubber membrane that covers every detail, flashing and penetration. It is a ‘belt and braces’ approach that ensures the physical security of the assets below. And because silicone is hydrophobic and resists
The roof is a primary asset for energy efficiency
ponding water (standing water), it offers resilience even on flat roofs where drainage can be an issue.
THE ROOF AS A STRATEGIC ASSET In an era where data centre capacity is being built at record speed, there is a temptation to value speed of construction over material performance. However, as energy grids tighten and climate reporting becomes mandatory, every efficiency and longevity win counts. Reducing the thermal load on a facility extends the life of chillers, fans, and compressors. It
delays the need for CapEx-heavy equipment replacement and lowers the PUE. The roof is much, much more than just a lid over
the servers; it is a vital part of the building’s energy efficiency. By selecting a high-performance, waterproof and reflective roof coating, data centre operators can lock in decades of thermal performance, securing their digital assets and supporting their sustainability goals in one move.
