ATLANTA - A large collection of new technologies for emerging applications is contained in ASHRAE's newly published BACnet standard.

ANSI/ASHRAE Standard 135-2010, BACnet - A Data Communication Protocol for Building Automation and Control Networks, allows building equipment and systems manufactured by different companies to work together. It is the only open, consensus-developed standard in the building controls industry. The new standard contains 19 addenda approved since the 2008 standard was published.

"The 2010 version of the standard represents a large amount of work in a short amount of time by the BACnet committee," Dave Robin, committee chair, said. "In just two years, the committee has added a wide variety of new technologies and contributed more than 400 pages to the standard."

The standard contains several new ways to communicate: wireless communications is provided for applications where wired networks are impractical or expensive; a new XML vocabulary is provided for complex standard and proprietary data and metadata; a new character encoding method is provided for greater flexibility and compatibility with international text; and new state-of-the-art network security is defined to allow the creation of highly secure communications channels for sensitive data.

 It also adds:

  • higher speeds for MS/TP networks and wiring guidance for optically isolated segments
  • new requirements for workstations and the definition of new kinds of workstations
  • new engineering units to support smart grid and other emerging applications
  • a new Global Group object for gathering, monitoring and distributing sets of data
  • six new objects to support physical access control
  • 12 new objects to support the full complement of all data types, including strings

The cost of ANSI/ASHRAE Standard 135-2010, BACnet - A Data Communication Protocol for Building Automation and Control Networks, is $170 ($140 ASHRAE members).
