A building automation system or BAS is a network of controlling and monitoring devices mainly responsible for the heating, ventilation, and air conditioning (HVAC) control system in large facilities and commercial buildings. Building automation systems are most commonly implemented in large facilities such as healthcare facilities, schools, universities, hotels, residential buildings, and data centers. A BAS network allows building operators to supervise and control the HVAC systems from a centralized location known as the Building Management System or BMS. VAV system, the air handling unit (AHU) and the VAV boxes are physically separated from each other, and each one has its own controller, also distanced from one another. However, for a VAV system to operate effectively, the VAV Boxes and the AHU have to talk to each other; in other words, they need to share information to properly adjust their setpoints based on zone heating or cooling demand.

Understanding Power Factor and Its Correction
What is Power Factor?
The power factor is a measure of how effectively electrical power is being used. It is the ratio of real power to apparent power in a system.
Why is Correction Needed?
Low power factor leads to increased energy losses and higher electricity bills. Correcting the power factor improves energy efficiency.
Correction Methods
- Capacitor Bank Installation
- Improved System Design
- Use of Synchronous Motors
