BACnet Interest Group Europe Celebrates 25 Years

Many years of successful engagement – today over 120 members

In 2023, the BACnet Interest Group Europe (BIG-EU) turned 25. The organization celebrated its anniversary and 25 successful years at the ISH trade fair in Frankfurt (March 13–17, 2023).

The BIG-EU was founded on May 14, 1998, when more than 40 representatives of building services companies, universities and industry organizations from the USA and all over Europe met to discuss the establishment of a European organization for the further development and dissemination of the BACnet standard.

Important impulses came at the meeting from Mike Newman from the USA, also known as “Mr. BACnet”. Mike Newman, who unfortunately passed away in 2020, is considered the spiritual father of the BACnet protocol (ANSI/ASHRAE Standard 135-1995). When he took over the operation of an energy management system at Cornell University, Ithaca NY in the mid-1970s, he found that all the building automation companies were starting to offer DDC equipment, but none of them could communicate with each other. A quote: “I began to wonder who was working on a standard protocol. It was clear to me that the lack of a standard would eventually be a major obstacle to the widespread adoption of DDC technology.” At that time, when IBM introduced an integration protocol “FACN” for their sites, Mike Newman contacted ASHRAE in late 1986. This was the impetus for standardization work in ASHRAE Working Group 135. The resulting ANSI 135 protocol was trademarked as “BACnetTM” from 1992 and has been the worldwide ISO standard 16484-5 since 2004.

17 participants from Europe and the USA then founded the association BACnet Interest Group E.V, initially also known as “BIG”, on May 14, 1998. Founding members were the companies Alerton, Elektrowatt (Landis & Staefa, Cerberus), Honeywell, Johnson Controls, CA Computer Automation, IfR Institut für Regelungstechnik, Kieback+Peter, Regin Technology, Siemens Switzerland Limited, Trane, EIBA, FH Dortmund (Department of Communications Engineering), Gimelec, Planungsgruppe M+M, Schneider Electric, Triple S, VTT Building Technology and BUS-House. The overview shows that the BIG-EU was well anchored in the industry from the very beginning.

The first three-member Board consisted of President Nils Meinert (Landis & Staefa), Vice President Karl Heinz Belser (Honeywell) and Treasurer Volker Röhl (Johnson Controls). All members of the first board have remained loyal to the association over many years and have supported it with their commitment.

Immediately after its foundation, the BIG-EU started with a variety of activities. In 1998 it participated in the Building Performance Congress in Frankfurt, in 1999 there was a first BACnet Symposium, in 1999 the BIG-EU was represented for the first time with a booth at the ISH and in 2000 at the Light + Building. This was followed by many other trade fair participations throughout Europe. At the same time, programs for education and training were started. An important regular event is the BACnet Plugfest. Here, participants from many different building automation suppliers from all over Europe meet and test their newly developed BACnet products for interoperability. All these activities contributed to a fast and continuous increase in membership.

Already in 2004 the first own journal of the BIG-EU was published, the first issue of the BACnet Europe Journal. In the meantime, the BACnet Journals are available in three versions: The bilingual (English/German) BACnet Europe Journal has already been published 39 times, the French BACnet France Journal 15 times and the English BACnet Middle East Journal 11 times.

Important for the dissemination of the BACnet standard and its further development are the technical committees and working groups. Several members of the Technical Working Group actively participate in the ASHRAE BACnet Committee and in the affiliated BACnet working groups. It deals with extensions to the BACnet Standard, the development of testing, listing and certification, technical questions from users and developers, and qualification measures. The Marketing Working Group is responsible for communication at trade fairs, symposia and in the media.

In the 25 years of its existence, the BIG-EU has entered into numerous liaisons and collaborations with other associations and organizations as well as the public sector in the field of building automation. The Working Group Facility Management, which was founded in 2022 and focuses on the operation of buildings and the topic of “BACnet and facility management”, is still very young and is open to anyone interested, even without BIG-EU membership. Another current topic is elevator integration with BACnet.

Today, the BIG-EU has over 120 members. They are looking forward to another successful 25 years with their organization, the BIG-EU.
