Building Energy Management System (BEMS) is used to collect the building data and then analyze the building energy system.¡¡Recently, many studies have been conducted to develop machine learning models using the BEMS data, and to control HVAC systems based on the data-driven simulation model called Model Predictive Control (MPC). In this study, a Gaussian process model was developed to estimate the performance of six cooling towers in a real building and set sequencing control of cooling towers. It was found that power consumption was reduced from 39,340kW to 28,230kW, and the energy saving rate was about 28%. |
