초록

Today, about 1% of the global electricity is eaten up by data centers. The ongoing global digital transformation in conventional growth and capability will not only boost the number and size of data centers but also their energy consumption and carbon footprint. In Korea, data centers, became the largest users of energy consumption, spend an average of 208,480 toe annually in 2017. Data center energy consumption was the highest among the building types. Because of the higher energy consumption, energy efficiency becomes more and more important. However, insufficient energy data has been a significant barrier against fully understanding of energy use characteristics, and demand load features of data centers. This study aims to develop an energy baseline standard to tackle the questions of energy efficiency for data centers. Many data centers have utilized a statistical data which may not fully capture the energy flow within the IT sector and Non-IT sector. With the goal of overcoming these limitations, a methodology to reveal the data center energy flow and the energy baseline based on IT load were developed. Taking S telecom data center for case study, this paper proposes systematically how to make and analyze the energy structure. First, equipment-level energy efficiency is the best resources to help energy saving in data center be it large or small. Second, building-level energy efficiency is related to numerous operating characteristics that are identified as potentially important for data centers.
