A Building Automation System (BAS) is a computer-based system that automates the control of a building’s heating, ventilation, air conditioning, lighting, security, and other systems. The BAS is designed to provide a comfortable and safe environment for occupants while minimizing energy consumption. The system is composed of a network of sensors, controllers, and actuators that communicate with each other to monitor and control the building’s environment. The BAS can be programmed to control a variety of functions, such as temperature, humidity, lighting, and security. It can also be used to monitor energy usage and provide data for energy efficiency initiatives. The BAS is a key component of a building’s overall energy management strategy, as it helps to ensure that the building is operating at peak efficiency and comfort levels. The BAS is also an important tool for building owners and operators, as it can help them identify areas of energy waste and provide insights into how to reduce energy consumption.
