Building Automation Systems

What is a Building Automation System?

A Building Automation System (BAS) is used to control the many tasks that are required for your HVAC to run efficiently. Think of it as the “brain” of your building. The system provides a user interface that allows the end user to adjust the control settings, view the status of the system, and detect any performance issues.

Why BAS?

Building Automation Systems (BAS) are key to helping building owners and operators understand what is happening inside their building.  BAS also gives property managers a way to monitor, analyze, and correct building operations.

At Casto Tech, we believe that helping our customers understand, and operate their BAS system is key to building operation. Whether the issues are occupant comfort or equipment productivity, we can deliver a system that helps you meet your building’s needs.

Controls System Integration with Casto Technical Services


Integrating building automation systems (BAS) to the latest technology is a decision that many businesses make to ensure that their buildings are running efficiently. 

At Casto Technical Services, Inc., we are committed to earning your business without holding you captive to proprietary software and applications by using the Niagara AX Framework (NAF).

What does this mean? An open protocol system (NAF) does not tie you into one brand or another. We understand all systems are not created equal. What is suitable for one application may not be right for another. Therefore, we utilize the NAF system. Casto can take your working BAS system, integrate it with the NAF system, and gives you true interoperability. The sharing of data makes each system smarter, expandable, and more functional.

If you are a business in West Virginia, Ohio, Virginia, Maryland, Kentucky, or Pennsylvania, contact Casto Tech to set up your controls system integration today.
