Smart Building for Energy Management using IoT at Coal-Fired Power Plant Facilities

In the context of increasing energy consumption and greenhouse gas emissions, this study explores the implementation of a smart building system using Internet of Things (IoT) technology at the Lontar Coal-Fired Power Plant (CFPP)’s administration building. The primary objective is to optimize energy usage without significant changes to existing infrastructure, aligning with ISO 50001 Energy Management System (EnMS) standards. An initial energy audit revealed high consumption, particularly from outdated air conditioning systems. The study highlights the innovative use of IoT devices, such as smart meters, sensors, and remote controls, enabling real-time monitoring and control of energy consumption. This approach provides a cost-effective solution for improving energy efficiency without requiring major infrastructure upgrades. Key findings include a 11.67% reduction in energy consumption, particularly in air conditioning and lighting systems, leading to substantial cost savings and reduced CO2 emissions. Furthermore, the project demonstrated the scalability of IoT for improving energy performance across large facilities. This study underscores the potential of IoT to drive energy efficiency, ensure compliance with environmental regulations, and offer a low-investment, high-impact solution for sustainable building management.
