BTL-Working Group (BTL-WG)

The core of the BTL is the BTL Working Group with its voluntary members as well as the BTL Manager. The working group was formed by BACnet International to maintain and continuously improve the BACnet conformance certification and listing program.

The BTL Working Group is open to anyone who would like to participate in developing and maintaining the BTL Testing program. Voting members are members of BACnet International and BIG-EU. Voting members are selected from knowledgeable experts in the BACnet community and serve 5-year terms.

The BTL-WG provides oversight and guidance to the BACnet Testing Laboratories (BTL) and certification program for BACnet products. The BTL is responsible for the technical aspects of BACnet International’s testing and listing activities, the central goal of which is to improve BACnet interoperability between building automation products.

The BTL-WG is a technical resource of BTL focused on the real-world interoperability of BACnet products. It is a largely volunteer committee of technical experts that maintains, extends, and enhances the BACnet product test requirements and testing policies. The committee’s responsibilities and actives include:
