Building Communications and Protocols: Creating the Right Mix for the Right Application

December 06, 2022

Market conditions, including energy regulations, labor and material shortages, cyber-attacks, and of course the recent pandemic, are creating evolving customer needs. Building owners, facility teams, and service providers are now requiring more data, flexibility, secure remote access, and risk management.
While connected buildings can provide these features, the various ways these buildings and their systems communicate can provide differing advantages. For example, wireless BACnet/Zigbee communication with self-healing mesh can provide redundancy and reliability while BACnet/IP communication can provide faster data speeds.

Learn the protocols, considerations, and application factors to help choose the right building communication medium for your system.

Learning Objectives:

  1. Identify the various protocols, mediums, and topologies available for building communications.
  2. Discuss the key considerations for choosing a communication protocol—including BACnet, Modbus, LonTalk and proprietary languages.
  3. Explore the application factors that would lead you to choose communication mediums, between wired and wireless, and topologies.
  4. Describe how to mix and match communication mediums, protocols, and topologies for optimal system, design.

Building Pressure Control Engineers Newsletter LIVE
In this program, we will review the factors that influence building pressure. We will also explain how HVAC system operation can impact ventilation airflow rates, exhaust rates, and the resulting building pressure. Then we will demonstrate and discuss several common building pressure control techniques and controls using a model building. Finally, we will review several industry standard requirements related to building pressure control.
