Official Website of ASHRAE SSPC 135
This Website is dedicated to providing the latest information on BACnet - A Data Communication Protocol for Building Automation and Control Networks. Developed under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), BACnet is an American national standard, a European standard, a national standard in more than 30 countries, and an ISO global standard. The protocol is supported and maintained by ASHRAE Standing Standard Project Committee 135 whose members have created and provided the content for this Website.

Here you will find the latest BACnet news, the status of SSPC 135 activities, a comprehensive bibliography of BACnet publications - many of which are available on-line - along with a wealth of other information. In keeping with ASHRAE's long-standing tradition and policy of non-commercialism, this site contains no advertising. However, BACnet's success depends on the implementation of BACnet in commercial products. Thus, we are pleased to offer links to the Websites of manufacturers who are supporting BACnet through their product offerings.

The SSPC welcomes your comments and suggestions concerning this site!

  • BACnet Readies RESTful Web Services for a Plugfest in the Fall! (7/13) Denver, CO. The BACnet Committee has been working on a second version of the BACnet Web Services (BACnet/WS) which provides a protocol neutral interface for Building Automation Systems to facilitate connection to the Enterprise. This will provide a more capable and secure interface for enterprise applications allowing access to more of the data found in Building Automation Systems.  

    This new RESTful version of BACnet/WS extends the logical data model with more complete data modeling, subscriptions, semantic tagging for searching and filtering, and security based on TLS and OAuth2.0. Users will enjoy greater flexibility of data management as well as increased throughput. Seven companies (Automated Logic, Cimetrics, Delta Controls, MBS, PolarSoft, Siemens, and Trane) have committed to participating in a BACnet/WS plugfest in late 2013 which will test the interoperability of BACnet/WS implementations.

    “We are making good progress towards a public review version of the new RESTful BACnet Web Services,” said Carl Neilson, BACnet Committee Chairman, “which will bring an enhanced connection between enterprise applications and building automation data.”
