Heading the list of on-going tasks is the completion of the companion standard to BACnet called "Testing Conformance to BACnet." This document specifies in complete detail how to test every aspect of the protocol and will be the basis for the BACnet certification program. To facilitate interoperability and to help designers more easily specify BACnet systems, the BACnet committee is developing device profiles and a specifier's guide. Two addenda provide a variety of new and improved features. ISO/TC205 is working to complete the adoption of BACnet as an international standard. Part of this will be a specification of how to link to European Installation Bus products. The "Open BACnet Internet Wide Area Network" (OBIWAN), sponsored by BIG-NA, will allow users to view data from BACnet systems around the world via a web browser.
