Abstract [en]

The increasingly power load of datacenters worldwide and consequently, the increase on heat dissipation by electronic components, have been highlighting the importance of efficiently designing cooling solutions for such systems. In fact, bad management of the cooling system can greatly increase the total electricity consumption in a datacenter. This being said, TeliaSonera in order to decrease the total electricity consumption in its datacenters, has developed a new cooling solution known as the Green Room concept. Therefore in order to evaluate the potential environmental benefits related to this product, this work was developed. The Life Cycle Assessment methodology in accordance to ISO 14040/43 standards was applied to assess its environmental performance, from cradle-to-grave. Moreover the software SimaPro, the Ecoinvent database and the ReCiPe impact assessment method were also utilized.

The results emphasized the phases and activities during Green Room life cycle presenting the highest potential impacts. This being said, the utilization phase presented for every impact category analyzed the highest potential impacts, with exception of ozone depletion category, which was dominated by material extraction and manufacturing phase, due to the presence of R134a refrigerant. In addition transportation phase presented the lowest values for every category and the end of life phase exposed considerable impact mitigation for the whole life cycle. Moreover extraction and manufacturing phases presented copper, steel and the refrigerant R134a as the most impacting materials for damage to human health, damage to ecosystems and damage to resources, respectively. Finally, improvements were proposed in order to increase the environmental performance of this cooling system.
