National Taiwan University of Science and Technology (NTUST) operates a campus-wide Smart Energy Management System that integrates electricity, water, chiller, VRV and street-lighting data into a single web platform to support energy- and water-saving management. For water, digital meters are installed at every point where the municipal mains supply enters the campus, and sub-meters are installed in the major buildings. Together, they measure in real time and continuously the total volume of water the university takes from the mains supply.

On the system home page, the “Campus Water Information” panel shows the university’s cumulative water use for the current day and month. The “Water Information” page presents a piping diagram of the three mains intake points (Main Inlet 1, Main Inlet 2 and the Research Building inlet) and the building sub-meters (Administration Building, Library, teaching buildings, dining halls, student dormitories, swimming pool, etc.). Each meter shows its cumulative daily and monthly consumption in cubic metres (m³). “Data Query” and “Statistical Report” functions let users retrieve historical water data by day, month and year.

• Total mains-supply metering: Digital meters at the main water inlets (Main Inlet 1, Main Inlet 2 and the Research Building inlet) measure the total volume of water the university draws from the municipal mains supply.
• Building-level sub-metering: Sub-meters in major buildings show how water use is distributed across campus and point to high-consumption areas.
• Real-time monitoring and leak detection: Daily and monthly totals update continuously, so facility staff can spot leaks or abnormal use early and respond quickly.
• Reporting and continuous improvement: Historical queries and statistical reports track consumption trends, measure how well water-saving actions work, and support annual water-use targets.
