"Below are two direct links that you are welcome to share with your colleagues and customers. The first is a link to the playback of the webinar. The second is to a set of documents which we refer to as the BACnet Competitive Analysis Pak (or CAP). These set of documents will help you stay informed as to the market and technical differences between the two approaches to creating ‘open’ building networks and smart grid aware facilities.
We will update the BACnet CAP with revised and new information as required, so you should expect to receive the occasional update from us informing you of changes."
