An energy management system (EMS) is a set of tools and processes designed to monitor, control, and optimize energy use in buildings or industrial facilities. By collecting data on energy consumption, an EMS helps organizations identify inefficiencies and implement strategies to reduce energy costs and environmental impact. These systems often integrate with smart technologies, such as smart meters and IoT devices, to provide real-time insights. An effective EMS can lead to improved energy efficiency, reduced greenhouse gas emissions, and enhanced sustainability practices, benefiting both the organization and the environment.
