CHICAGO — If you listened carefully to what was being said by exhibitors in the designated Building Automation and Control Showcase area at the 2003 Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), chances are the words “interoperability” and “open system” cropped up sooner or later.
To no one’s surprise, manufacturers continue to develop ways to make systems and products from multiple vendors communicate with one another, and there were plenty of new building automation systems and building controls introduced at the expo.
