Energy consumption practices and efficiency measures Despite a significant increase in ICT load and the growing number of colocation customers over the past three years, the company’ s energy consumption has remained stable.
This remarkable achievement is the result of several strategic initiatives. A1 has focused on consolidating its infrastructure and implementing advanced technologies that enhance power usage efficiency and reduce cooling requirements. The company’ s data centres use energy-efficient cooling systems such as free-air cooling, minimising energy demands for temperature control.
Through infrastructure consolidation, the use of low-power hardware, and virtualisation, A1 has been able to optimise its ICT footprint while keeping energy consumption steady, in line with regional and global sustainability goals. This approach not only reduces operational costs but also significantly minimises the company’ s environmental impact.
Given Croatia’ s climate, the company makes the most of free cooling methods,
