Abstract
Data centers play a critical role in supporting global IT infrastructure, representing a rapidly growing industry. However, this growth is coupled with significant environmental consequences, such as the consumption of 1-2% of the annual global energy supply, increased carbon emissions, and the loss of valuable agricultural land. This study reviews solutions that address these impacts by evaluating sustainable practices in data center construction, design, and maintenance. The results point to several key strategies that improve environmental sustainability in these categories. In construction, replacing traditional materials, such as concrete and steel, with eco-friendly alternatives such as green concrete and steel slag can reduce carbon footprints. Additionally, permeable pavements can manage the stormwater runoff that was previously absorbed by the farmland on which data centers are built. Design improvements, including underfloor air distribution, economizers, ice storage, and energy recovery wheels can optimize ventilation systems, lowering energy demands by up to 25%. Sustainable maintenance practices emphasize the use of advanced liquid cooling systems, as well as thermal energy storage to reduce peak electricity usage and incorporate more renewable energy sources. Overall, it is vital to implement strategies that prioritize sustainability in data centers in relation to the construction, design, and maintenance to reduce the environmental footprint of this growing industry.
