  1. Before BACnet...

  2. After BACnet...

  3. Reasons for BACnet's success: • BACnet is the only standard protocol designed specifically for building control. It was designed from the beginning to support: • Alarm and event processing • Command prioritization • Scheduling • Trending

  4. Reasons for BACnet's success: • BACnet doesn't depend on current technology • BACnet is implemented through software, not hardware • BACnet's objects and services are independent of the underlying network technology • BACnet/WebServices allow communication between BACS and enterprise applications (for example: room scheduling, energy monitoring)

  5. B C Vendor A Vendor A Vendor Vendor Reasons for BACnet's success: BACnet LAN - Ethernet, ARCNET, MS/TP, LonTalk, or BACnet/IP • BACnet has no fixed architecture. Can be flat: BACnet Workstation BACnet Field Panels Sensors and Actuators

  6. Vendor A Reasons for BACnet's success: • Or BACnet networks can be hierarchical: Net 1 BACnet LAN - Ethernet BACnet BACnet Workstation Field Ethernet to Panel ARCNET Router Ethernet to Sensors and Actuators MS/TP Router Net 2 Net 3 BACnet LAN - ARCNET BACnet LAN - MS/TP BACnet BACnet C B B Vendor C Vendor Vendor Vendor Field Field Panels Panels Sensors and Actuators Sensors and Actuators

  7. Reasons for BACnet's success: • Can be implemented in devices of any size • Application specific controllers • Configurable, fixed-program controllers • General purpose, programmable controllers • Workstations and Web servers

  8. Reasons for BACnet's success: • Most BACnet devices are actually small...

  9. Reasons for BACnet's success: • BACnet can be easily enhanced to embrace building technologies beyond HVAC&R: • Access control • Elevators • Lighting control • Utility integration • Video surveillance

  10. € ¥ $ Reasons for BACnet's success: • No charge for BACnet's use - no fees, licenses, or royalties. BACnet is an ISO standard.

  11. The Biggest Reason for BACnet's success? People from all over the world Communication specialists Building automation engineers Building owners Government officials Manufacturers Building operators Software engineers and programmers working together!

  12. BACnet and China The BACnet community looks forward to working with our colleagues from BIG-CN, SAC/TC426 and elsewhere to make BACnet a success in China and worldwide! 谢谢！
