ELISA: Real-Time Energy and Water Monitoring for Sustainable Campus Management

Elisa is an online monitoring system designed to track the usage of electricity and water, helping users build awareness of energy efficiency and cost-saving potential. It collects and analyzes real-time data on energy consumption across different buildings and faculties, offering insights into daily, monthly, and real-time electricity usage. The system integrates IoT technology and features a digital power meter to measure electrical parameters such as current, voltage, and power. The data is transmitted using a Modbus protocol to a server, allowing users to access and analyze energy data remotely. Elisa’s dashboard offers features like daily and monthly consumption summaries, energy distribution heatmaps, and comparisons between faculties. It also enables users to monitor energy balance in three-phase systems, providing valuable information for optimizing energy management and reducing operational costs.

Through the ELISA dashboard, ITB can accurately measure the total volume of energy and water usage across the university. This includes real-time monitoring of power consumption, electrical current, and voltage over specific periods, such as the last hour. Users can track daily and monthly energy patterns, enabling efficient energy management and planning. The system’s heatmap feature highlights peak consumption times, categorizing energy use into High, Medium, and Low intensities. Additionally, ELISA allows for comparative analysis between buildings and faculties, helping ITB optimize energy efficiency based on specific metrics such as building size and student population.
