A large collection of new technologies for emerging applications is contained in The American Society of Heating, Refrigerating and Air-Conditioning Engineer’s (ASHRAE) 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.
The cost of ANSI/ASHRAE Standard 135-2010, BACnet – A Data Communication Protocol for Building Automation and Control Networks, is $170 ($140 ASHRAE members).
