Regulatory requirements for sustainability
Data centres face intensifying pressure to shrink their environmental footprint. Regulations such as the EnEfG and NIS2 tighten compliance obligations and compress implementation timelines.
The real test is translating decarbonisation targets into day-to-day operations: integrating renewable energy, capturing and reusing waste heat, and lifting overall efficiency often within tight spatial, technical and legacy constraints. A pragmatic path combines sustainable, modular design with partnerships for district heating, the use of resource-efficient materials, and the consistent specification of high-efficiency power components across the entire chain.
Measuring energy overhead in data centres
To gauge how much energy goes to non-IT services like cooling and power conversion, operators track PUE (Power Usage Effectiveness). It’s calculated by dividing a site’s total energy use by the energy drawn by the IT load. The closer the figure is to 1.0, the smaller the overhead.
Formula: PUE = total facility energy ÷ IT load energy
PULS solutions for sustainable data centre operation
PULS power supplies make a direct contribution to lower energy consumption across the entire facility. Their exceptionally high efficiency minimises power losses and reduces heat generation, which in turn lessens the demand on cabinet cooling systems. Even in standby or no-load conditions, PULS units consume very little energy, helping to cut the overall footprint of auxiliary loads.
With long service life, low maintenance requirements and compact dimensions, PULS solutions support operators in meeting PUE targets, reducing operating costs and aligning data centre infrastructure with ambitious sustainability goals.
