Abstract

DCSim developed in this study is characterized by its integration of specific features unique to data centers. It streamlines the computation of cooling loads, thus minimizing the burden of input, and delivers energy consumption data for data center cooling systems with a level of precision comparable to that of commercial dynamic energy analysis tools. This empowers data center engineers to make informed decisions based on energy efficiency enhancements, thereby strengthening their ability to improve energy efficiency. The accuracy of the DCSim tool was verified by comparing it with DesignBuilder v7.0.2.4, a commercial building energy analysis software based on EnergyPlus. The hourly power data for each piece of equipment calculated using both tools were compared. The CVRMSE (Coefficient of the variation of the root mean square error) ranged from 0% to 9.3% for the chilled water system, and from 1.4% to 10.75% for the air-side economizer.
