The study detailed the development of a real-time kWh consumption monitoring system that aims at tracking electrical energy usage within the Main Campus of Don Honorio Ventura State University. Using sub-metering technology, the system captures more detailed data than conventional utility meters, enabling monitoring at the departmental or building level. An IoT-based platform was integrated with digital sub-meters to collect, transmit, and present real-time data through a web-based dashboard, providing stakeholders with clear insights into usage trends, peak demand periods, and historical consumption. The system was implemented in selected campus buildings to assess its reliability, usability, and overall performance. Findings showed that the monitoring system enhances energy usage visibility, supports efforts to reduce costs, encourages energy-efficient practices, and contributes to the university’s broader sustainability and smart campus initiatives.
