A Building HVAC Control System is a system that is designed to regulate the temperature, humidity, and air quality of a building. It is a combination of hardware and software that is used to control the heating, ventilation, and air conditioning (HVAC) of a building. The system is typically composed of sensors, controllers, and actuators that work together to monitor and adjust the environment of the building. The sensors measure the temperature, humidity, and air quality of the building, while the controllers use this data to adjust the HVAC system accordingly. The actuators are then used to make the necessary adjustments to the HVAC system. The Building HVAC Control System is an important part of a building’s energy efficiency, as it helps to ensure that the building is comfortable and safe for occupants. Additionally, the system can help to reduce energy costs by ensuring that the HVAC system is running efficiently.
