If it can open or close, turn on or off, or has a motor, it can be automated. Building automation can be described as a network of a building’s mechanical, HVAC, and lighting controls normally brought back to a central control system. Typical controls configurations in a building include mechanical systems, such as chiller plants, HVAC systems integrating air-handler units (AHUs), and VAVs (variable air volume units) throughout the building and lighting control systems. Building automation systems (BASs) integrate all of these building systems as well as create an energy-efficient facility. While there are dozens of best practices for engineers managing complex facilities, it’s important to get back to the basics of building automation: What can be automated and what are the benefits.
