- Copass Celebrates Pending Retirement! (10/18) Atlanta, GA. Surrounded by the BACnet committee, Cliff Copass, Johnson Controls, was presented a festive cake to commemorate his upcoming retirement and his many years of dedicated participation and contributions to the BACnet standard. As near as Cliff or any of us can recall, he has been actively working with BACnet since 2000, 18 years, more or less. If all goes as planned, this may be his last meeting and, come January when the committee is once again in Atlanta, Cliff and his wife will be basking in the sun (as indicated by the arm chairs and palm trees on the cake) in sunny Wisconsin - or maybe Florida. In any case, congratulations Cliff! Enjoy!
- Three More Addenda Go Out for Public Review! (8/18) Atlanta, GA. These three proposed addenda are undergoing a 45-day 1st Publication Public Review from August 17 to October 1, 2018:
Addendum 135-2016br; Addendum 135-2016bt; and Addendum 135-2016bu.
- New Errata Summary Available! (7/18) Atlanta, GA. OK, nobody is perfect. Errata, Latin for "errors", occasionally creep into technical documents - and BACnet is no exception. To make sure you are looking at the correct language in the standard, please visit our Errata page. And, of course, if you find a previously undetected error in the standard, please let us know!
- BACnet/SC Whitepaper Available! (7/18) Atlanta, GA. Two of the SSPC's top concerns for the last several years have been network security and "IT friendliness." Recognizing these concerns, the IT-WG has developed a new proposal centered on secure communications exclusively using accepted IT best practices. The new technology is called “BACnet Secure Connect (BACnet/SC)” and is the subject of this whitepaper. Simply put, BACnet/SC provides the means to create secure communications connections between BA devices both across the cloud, and within facilities. BACnet/SC uses the latest techniques for security and integrates easily with IT infrastructure. At the same time, BACnet/SC preserves 100% of the capabilities of, and is backward-compatible with, all existing BACnet deployments and devices. The whitepaper is available for download from our Bibliography page and the current public review version of the addendum can be downloaded here!
- SSPC 135 Installs New Officers! (6/18) Houston, TX.
Gathering for a ceremonial photo are the new officers of the BACnet committee. From left to right: Scott Ziegenfus, Secretary (Hubbell Lighting); Michael Osborne, Chair (Reliable); and Coleman Brumley, Vice Chair (Setra). Good luck, gentlemen, and thanks for stepping up! The SSPC also would like to express its thanks and appreciation to outgoing chair, Bernhard Isler (Siemans), for his tireless efforts over the last several years. In spite of living in Switzerland, Bernhard has never missed a meeting and now has more frequent flyer miles than just about anyone. Thanks, Bernhard!
- SSPC 135 Changes the Guard! (6/18) Houston, TX.
Among the highlights of the Houston meeting was the "changing of the guard" of SSPC 135's officers. Here current committee chair Bernhard Isler (Siemens) passes the gavel to incoming chair Michael Osborne (Reliable). Standing together are all living chairs of the BACnet committee except for Carl Neilson (Delta) who was unable to attend. From left to right, Mike Newman (Cornell), Dave Robin (ALC), Osborne, Isler, and Steve Bushby (NIST). The seventh chair of the committee, our dear colleague Bill Swan (Alerton), passed away in 2011.
- BACnet/SC Begins 2nd Public Review! (6/18) Atlanta, GA. ASHRAE has announced a 45-day Publication Public Review of Addendum 135-2016bj from June 1 until July 16, 2018.
This addendum introduces a BACnet Secure Connect Datalink
Layer Option and a BACnet/SC in the Network Layer
Specifications; adds new Annex YY for the BACnet Secure
Connect Datalink Layer Option; extends the Network
Port Object Type for BACnet/SC; adds and extends ASN.1
Types for BACnet/SC; introduces new Error Codes for
BACnet/SC; and defines Interoperability Specification Extensions
The addendum originated within the IT-WG as part of what had been referred to as "BACnet/IT", a revised specification for the use of BACnet in a more "IT friendly" manner. Since the addendum concluded its first Advisory Public Review in February 2017, the BACnet/IT discussion has morphed into deliberations on how "secure connections" can be implemented in an IT environment and Addendum 135-2016bj is the result.
- Fisher Receives Swan Award! (4/18) Fort Lauderdale, FL.
During the April 2018 plenary session of SSPC 135 in Plantation Florida, David M. Fisher, President of PolarSoft Inc. and SSPC participant since 1987, was presented with the 2018 Swan Award.
The award can be best described by using David’s own words: "This award, which is presented yearly, honors the memory of our dear friend and colleague, Bill Swan, a.k.a. BACnet Bill, who passed away in 2011. 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. This award carries 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."
Dave, by virtue of his tireless efforts to develop and improve the BACnet standard for more than 30 years, truly deserves this recognition. Congratulations, Dave, from the entire BACnet community!
- Fort Lauderdale Meeting Concludes! (4/18) Fort Lauderdale, FL.

- ASHRAE Standard 223P to Integrate Haystack tagging and Brick data modeling! (2/18) Atlanta, GA, Berkeley, CA, and Richmond, VA. The ASHRAE BACnet committee, Project Haystack and the Brick initiative announced they are actively collaborating to integrate Haystack tagging and Brick data modeling concepts into the new proposed ASHRAE Standard 223P for semantic tagging of building data.
ASHRAE Standard 223P "Designation and Classification of Semantic Tags for Building Data" provides a dictionary of semantic tags for descriptive tagging of building data including building automation and control data along with associated systems.
By integrating Haystack tagging and Brick data modeling concepts with the upcoming ASHRAE Standard 223P, the result will enable interoperability on semantic information across the building industry, particularly in building automation.
This unified effort is aiming at a formally standardized application data modeling solution which can be implemented in various ways. For example, it will be able to be used for exchanging data over established communication protocols like the Haystack web services or BACnet, or be applied on data stored in databases and cloud applications. The first public review of the initial draft of 223P is envisioned for late 2018. Ultimately, ASHRAE Standard 223P is intended to be adopted as an ISO standard.
Aside from the engineering and automation efficiency improvements machine-readable semantic descriptions of data will provide, a single and widely used global standard will enable broader interoperability among applications - creating a competitive market place to the benefit of building owners.
