Big data drives energy efficiency

The Building Analytics (BA) system is an efficient cloud-based solution that utilises big-data analytics to detect and diagnose potential equipment faults or operational irregularities. At HKIA, BA systems have been installed in the North Satellite Concourse and the Midfield Concourse since 2016, and was extended to Terminal 1 in June 2020.

The BA system makes use of more than 50,000 data points to examine a variety of equipment parameters and terminal conditions in real-time. This includes the operational status and energy efficiency of air-conditioning equipment, and the terminal’s temperature and humidity. It can also detect and determine the root cause of operational irregularities and make suggestions to improve energy efficiency. It is estimated that an annual energy saving of 3% can be achieved in Terminal 1 by using BA alone.
