Green School Bali, an international school which provides education for sustainability through entrepreneurial learning and natural environment won the Zayed Future Energy Prize for developing the new renewable energy projects. Currently, Green School is supported by 2 main power sources which come from Indonesian State Electricity Company (PLN) and Photovoltaics (PV) system electricity with power reach 23.1 kW and 21.6 kWp respectively. Both of the sources are distributed to the load based on

... he manual balancing and daily manual switching, which create the unbalanced load and high power loss. The key to achieving sustainable energy management is the availability of accurate measurement, recording, and analysis system of the power quality in the whole buildings. To meet the requirement of the sustainable energy management system at Green School, the monitoring system of the power and energy at Green School is developed. This system contains 2 data loggers and an Internet of Things (IoT) platform. The fixed data logger provides routine measurement and recording of power quality at the PLN meter, whereas the portable data logger provides the same function for each electricity panel. The monitoring system and human interface system integrate the intelligent humanmachine interface to an Ubidots platform and completed with online and offline data storage. This system is useful for supporting the sustainable energy management goal of Green School and the daily energy practitioner's work with providing a proper advance power monitoring system that has low cost and compatible with Green School system's demand. This project will also be used as a platform and teaching tool for students to develop similar projects and learn about IoT and cloud-based monitoring solutions with other measurements in the classroom.
