Welcome!
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!

  • BIG-RU to Launch BACnet Training Class! (2/12) Moscow, Russia. BIG-RU has finished the design and construction of a BACnet training facility at the Moscow State University of Civil Engineering. It features donated hardware and software from ABB, ALC, CAREL, Cimetrics, Delta, Johnson, Kieback & Peter, Sauter, Saia-Burgess, Siemens and Trend. The equipment, by vendor, is arranged in individual workstations or "stands," each of which has mock-ups of actual building systems with various sensors, actuators and control devices. All of the stands are interconnected via BACnet/IP so the overall facility represents a true multi-vendor environment. To take a YouTube tour of the training room, click here! The first training course entitled "Introduction to BACnet" is slated to start the week of March 5. Congratulations to BIG-RU and best wishes to its new BACnet students!
     
  • Chicago SSPC Meeting Concludes! (1/12) Chicago, IL. spacer Undaunted by a travel-snarling snowstorm, SSPC 135 began its full agenda of meetings with nearly 35 BACneteers from all over the world in attendance. The opening plenary featured liaison reports from the BACnet Interest Groups, BACnet International, BTL, IEIEJ, ISO/TC 205, CEN/TC 247, SPC 201P, and NAESB, among others. The IEIEJ presented their proposal for a new object type, the Commander.

The EL-WG proposal also contains three new services that allow for subscription to, and notification of, multiple Change of Value (COV) events with a single message. The IT-WG continued to explore options for making BACnet "more IT-friendly" and the IP-WG continued work on the Network Port object type. More details to follow.

  • First Swan Award Presented to Bernhard Isler. (6/11) Montreal, QC. spacer The BACnet committee has been looking for a way to memorialize our departed friend and colleague, Bill Swan. (See a short tribute to Bill from the other BACnet committee chairs, past and present. You can also visit his wife Kathy's Memorial Website.)

    During the June 25 plenary session of SSPC 135, David Fisher, president of PolarSoft Inc. announced the creation of the "Swan Award":

    "This award, which is to be presented yearly, honors the memory of our dear friend and colleague, Bill Swan, a.k.a. BACnet Bill, who passed away this month. We want to remember him always not only for his substantial dedication and contributions to BACnet, but also as a good and honest man, devoted to his family and faith," said Fisher.

    "By creating this award, we carry on Bill's example of even-handedness, rational and considerate discussion, and a focus on how to make the standard better for everyone. The award honors those individuals who through their actions demonstrate the qualities of integrity, selflessness, camaraderie and fierce dedication to the standard that we admired in Bill."

    spacer The 2011 Swan Award was presented to SSPC Secretary Bernhard Isler of Siemens Switzerland Ltd. "It is our intent to continue to sponsor these awards in the future," explained Fisher, also noting that he had already received inquiries from other organizations within the BACnet sphere who are interested in sharing sponsorship.


     
  • SSPC Makes Progress on 15 Addenda in Montreal! (6/11) Montreal, QC. Ten addenda to BACnet-135 and five to BACnet-135.1 were moved forward at the grueling SSPC session in Montreal:

    2. Addendum 2010ae clarifies and extends the physical access control objects
    3. Addendum 2010af is a very large revision that aligns and extends alarm detection and reporting capabilities throughout the standard

    Seven addenda to 135-2010 were voted out for public review:

    1. After a long gestation, a new version of the lighting addendum, 2010i, was voted for its fifth public review
    2. To go along with the lighting addendum, a new WriteGroup service was created and voted for its first public review as Addendum 2010aa

    6. The new Addendum 2010am is a very large addition to BACnet Web Services that allows REST (HTTP) communications for a variety of new types of data exchange, including:
      • structured/complex BACnet data
      • smart grid data models being defined by SGIP-related groups
      • other media types (documents, etc)
      • subscriptions and active notifications
      • chaining the retrieval of large datasets like trend and event logs.
    7. An extension to MS/TP in a new addendum, 2010an, allows for "large frames" to handle new applications like IPv6 over inexpensive twisted-pair wiring

    Five addenda were voted out for Public Review for the Testing Standard, 135.1:

    Addenda 135.1-2009j, k, l, m and n, completed their first public reviews in May and were modified and voted for second public review at this meeting.

  • European Plugfest 2011 to Take Place May 11-13 in Saarbrücken. (4/11) Dortmund, Germany. spacer BIG-EU has announced that the 5th BIG-EU Interoperability Workshop, also known as a "Plugfest," will take place May 11-13 in Saarbrücken, Germany.

  • BIG-EU's BACnet Booth at ISH 2011 Largest Ever! (3/11) Frankfurt, Germany. spacer "ISH" used to be called the "International Trade Fair Sanitation Heating" but has long since branched out into what organizers claim is "the world's leading trade fair for bathroom design, building, energy and air-conditioning technology and renewable energies." Now labeled the "International Trade Fair for House Building Technology," building automation displays take up most of one hall at Frankfurt's gigantic exhibition facility, Messe Frankfurt. Of this year's 204,000 visitors, a goodly number passed through BIG-EU's largest booth yet. Featuring 21 networked devices and over 1,000 data points from 15 exhibitors, the exhibit showed in a powerful way the capabilities of BACnet.

    But the BIG-EU organizers didn't stop with just the technical exhibits. A "BACnet Beerfest" was celebrated each day, starting one hour before closing time. Exhibitors and customers alike were able study the potential of individual BACnet systems and applications while enjoying a cold brew! Each day featured a different well-known European or Mexican brand and, of course, on St. Patrick's Day the Beerfest had to serve Guinness!
