Numerous data centers have been built and operated since 2000. Now that 20 years have passed, a growing need for remodeling that involves shifting to a new IT environment, upgrading IT equipment, and replacing outdated facility infrastructure is escalating. In this study, three basic independent non-IT system modules for a total IT load of 150 kW were derived to respond to low-density, medium-density, and high-density rack-server configurations according to the IT power density known as a key element of a data center. Additionally, a data center’s cooling strategies were analyzed according to its IT power density. As of 2021, the average IT power density of global data centers was surveyed at the level of 7.8-8.4 kW/rack that involved more than 400 samples. Data center cooling was divided into a room-based cooling for low-density, row-based cooling for medium-density, and rack-based cooling for a high-density IT load. Compared to the ALT-1 of a low-density model, the required area was reduced by 30% for the medium-density model and 55% for the high-density model. As a result of the remodeling cost analysis, the cost increased to 105% for the ALT-2 and 119% for the ALT-3 based on the ALT-1 being 100%. The criterion for data center remodeling is to comprehensively consider the required space, cooling energy efficiency, and construction cost based on the IT power density.
