This advanced course focuses on the latest available technology

and practical scenarios of communication and networking between direct digital control (DDC) controllers and DDC systems. The course also addresses frequent questions such as How to upgrade existing HVAC DDC systems? What are the advantages and disadvantages of open systems? How to integrate various building automation systems?

This short but powerful course is structured to enable students to better design and understand HVAC DDC systems and emphasizes critical “Do’s and Don’ts” as well as accepted rule-of-thumb checks in HVAC DDC. The significance of web-based open-building automation systems strategies will be examined.

Course Highlights:

  • HVAC DDC System Architecture
  • Open System Interconnection Model
  • HVAC DDC Topologies and Protocols
  • Gateways to Closed Systems
  • Open Systems and Tridium Solution
  • Web Services and the Tridium Solution
  • Four Levels of Energy Dashboards
  • DDC Wireless Technology
  • Net-Zero Energy and Smart Building Automation
