  • ISO/TC 205 Meets in Cairo (11/07) Cairo, Egypt. BACnet Hat in GizaRising up out of the sands of Giza, a BACnet hat dominates the view of the Pyramid of Khafre on the outskirts of Cairo. Back in town, ISO/TC 205, Building Environment Design, was meeting to discuss, among other topics, the continuing development of the 16484 series of ISO standards on control system design, of which BACnet (16484-5) and its companion testing standard (16484-6) play a central role. These discussions take place in Working Group 3 among experts from Australia, Austria, Japan, Korea, Norway, Sweden and the U.S. Representing the U.S. and ASHRAE SSPC 135 were Steve Bushby and Mike Newman, Past Chairmen, Bill Swan, current Chairman and Dave Robin, Vice-Chairman. One result of the meeting was the determination that 16464-3, Functions, had finally been republished by ISO to correct the mis-publication of an earlier draft version. Also, discussions of 16484-4, Applications, and 16484-7, Implementation, centered on providing suggestions to the drafting committee within CEN/TC 247. These two parts are under "CEN lead" pursuant to the "Vienna Agreement" between ISO and CEN that is designed to prevent duplication of work on the same area of standardization by both ISO and CEN committees.

  • Ooops! New Version of Addendum k to be Reviewed (10/07) Atlanta, GA. An incorrect version of BSR/ASHRAE Addendum k was posted both here and on ASHRAE's Website. The correct version is now posted and the public review has been extended until December 10, 2007. This proposed addendum adds support for one "Character Encoding Form" at a time. The rationale for this addendum is that "support" for character sets has not been well defined but is needed for interoperability. In addition, this addendum updates the standard to reflect the fact that the Japanese Industrial Standards Committee has changed the name of "JIS C 6226" to "JIS X 0208." The addendum can be downloaded from ASHRAE with associated comment forms or you can download just the revised public review draft by clicking here.
  • BI/BTL and BIG-EU Work to Strengthen Ties (10/07) Dortmund, Germany. In an effort to strengthen communication and to ensure that our mutual goal of consistent testing/listing/certification programs on both sides of the Atlantic is achieved, BI/BTL and BIG-EU have agreed that a liaison from North America will attend future meetings of BIG-EU in Europe. Carl Neilson (Delta Controls), Secretary of SSPC 135, has graciously agreed to serve in this role and attended his first meeting as liaison in Dortmund, Germany, October 9, 2007. In addition, Bill Swan (Alerton/Honeywell), Chairman of SSPC 135, was also able to attend in his new role as Buildings Standards Initiative Leader of Honeywell's Environmental and Combustion Control division. Considering that Bill will likely be able to participate in BIG-EU meetings into the future, the BIG-EU members decided to elect Bill to the position of Vice-President. Congratulations to Carl, Bill, BI/BTL and BIG-EU. We all look forward to working more closely together than ever before!
  • AMEV Publishes "BACnet in Public Buildings" (10/07) Berlin, Germany. AMEV, the "Arbeitskreis Maschinen- und Elektrotechnik staatlicher und kommunaler Verwaltungen" (Mechanical and Electrical Engineering Working Group of German National, Regional and Local Governments), has just published "BACnet in Public Buildings - BACnet 2007", a recommended practice guide for use by governmental authorities throughout the country. The guide was developed with the help of the BIG-EU and Hans Kranz of HAK Engineering, among others. It is aimed at providing guidance for designers, implementers and operators of BACnet-based building automation systems in government buildings of all types. The development and publication of the guide is particularly noteworthy since AMEV has, for years, been the principal advocate for the use of an "island-to-island" protocol (FND - Firm Neutral Datacommunication) which they had developed many years ago. As evidence of AMEV's commitment to BACnet, a joint meeting of AMEV and BIG-EU engineers was held in Dortmund on October 8 to discuss ongoing cooperation between the two organizations. You can download an Order Form for the German-language publication in PDF format and you can read AMEV's introduction to the document here.

  • Access Control, Lighting and Network Security Addenda Approved for Public Review (1/07) Dallas, TX. During the ASHRAE Winter Meeting, the BACnet committee recommended public review for six addenda to ANSI/ASHRAE 135-2004 (BACnet) and its companion testing standard, 135.1-2003. Three of these addenda extend the areas of building automation supported by BACnet.

    Addendum j to BACnet-2004, approved for first public review, adds physical access control to the areas of building automation supported by BACnet. This is the result of a four-year effort by the Life Safety and Security Working Group, led by convener David Ritter and comprised of representatives from both the HVAC and physical security industries from around the globe. Addendum j completes the extensions which started with Addendum f, the Access Door Object Type, now on its way to publication. The review period for Addendum j will be extended to 60 days to allow members of the access control community extra time to review the addendum. (A draft copy of the addendum is available here.)

    Addendum g, a new means for securing BACnet network communications, provides part of the base on which Addendum j is built. Developed by the Network Security Working Group and entering second public review with only minor changes, Addendum g draws on significant advances in encryption and authentication technologies. Addendum g will also be required for the access control extensions in Addendum j. "Trial implementations are underway," notes working group convener Dave Robin.

    Addendum i, approved for its first public review, will add support for lighting control systems to the BACnet standard. Lighting Applications Working Group convener Steve Karg noted that the extensions will support both sophisticated and simple lighting systems.

    The BACnet committee continues its work on a broad range of items including developing profiles for VAV controllers and VFDs, incorporating wireless capabilities, accommodating and adopting new IP technologies; and extending conformance testing to cover new BACnet capabilities.
