System Integrations: HVAC

HVAC systems typically form the backbone of most Building Automation Systems (BAS) in today’s smart buildings. The quality and maintenance of your HVAC system is a critical part of your building’s uptime and efficiency. The integration of HVAC automation with other systems in your building should be a primary consideration for retrofit BAS projects as well as the BAS design and implementation for new construction. With over 55 years of technical service and expertise, Brady understands the challenges that legacy systems and retrofit projects present, as well as the cutting edge technologies and systems that are powering the next generation of Smart Buildings.

How BAS Work

Before we cover HVAC integration considerations, let’s review some basic BAS concepts. Your BAS has five components:

Sensors 
These devices measure and record data about conditions in your building and mechanical performance. They might collect information about occupancy for a room or zone in a building, the humidity level, or the temperature.

Controller 
The data the sensors record is sent to the controller. Controllers come in various kinds and sizes, but they are basically responsible for reading the input data and sending commands to the various systems connected in the BAS.

Output Devices 
The output devices do the work the controller sends them. These actuators are what make the lights come on or dim, open or shut valves, etc.

Communication Protocols 
This is the language the BAS uses to communicate with the different parts of the system. These languages are open communication protocols (such as BACnet and LonWorks), proprietary (closed) protocols, or some mixture of the two.

Terminal Interface 
These interfaces display the available information from the BAS and give the end user the ability to monitor conditions in the building and control program settings.

This is a very simplified overview and description of the relationship of BAS components, but it gives us a useful foundation for understanding the complexity of integrating a new component, such as an HVAC unit, into a BAS.

HVAC Integration

One of the most important considerations in effectively integrating an HVAC system into your BAS is the communication protocol of the HVAC system. Systems that use one of the open communications protocols are easier to integrate into a retrofit project or include in an effective, scalable new construction design.

As HVAC technology and design continue to become more sophisticated, it is also important that the BAS can make effective use of the different kinds of data your HVAC system is collecting and using to operate its subsystems. This is where a BAS integrator like Brady can help you see the real possibilities for gains in efficiency and energy cost savings.
