The technology that assists in tracking energy consumption in buildings is called an energy management system (EMS). These systems utilize sensors and smart meters to monitor real-time energy usage, providing insights into power consumption patterns across different areas of a building. By analyzing this data, EMS can identify inefficiencies, facilitate energy-saving practices, and help comply with sustainability regulations. Additionally, they can manage heating, ventilation, and air conditioning (HVAC) systems to optimize energy use and reduce operational costs.
