What is the primary purpose of building automation systems (BAS) in HVAC?

Building automation systems (BAS) play a crucial role in HVAC management by controlling and monitoring systems that regulate heating, ventilation, and air conditioning. Their primary purpose is to enhance both the efficiency of these systems and the comfort of the occupants within the building. By utilizing sensors and automated controls, BAS can optimize energy usage, adjust temperature settings based on real-time data, and schedule operations based on occupancy patterns. This leads to energy savings, reduced operational costs, and improved indoor air quality, making the environment more comfortable for occupants.

While other options may mention aspects related to building automation, they do not align with the core goal of BAS. Some may even imply negative outcomes, such as increasing energy costs or promoting manual operation, which contradict the fundamental objectives of using automation in HVAC systems. Ultimately, the focus of BAS is on efficiency and comfort, underlining the significance of option B as the accurate answer.
