	Cover Pages: ASHRAE Releases BACnet Web Services Interface Specification for Public Review.
		BACnet — A Data Communication Protocol for Building Automation and Control Networks has been developed under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), BACnet is an American national standard, a European pre-standard, and an ISO global standard.
		BACnet became an ASHRAE/ANSI standard in 1995, and an ISO standard in 2003.
		BACnet is under continuous maintenence by the ASHRAE Standing Standard Project Committee 135.

	Bacnet
		BACnet is "a data communication protocol for building automation and control networks." A data communication protocol is a set of rules governing the exchange of data over a computer network.
		The rules take the form of a written specification (in BACnet's case they are also on compact disk) that spells out what is required to conform to the protocol.
		BACnet provides a standard way of representing the functions of any device, as long as it has these functions.

	Merdian Systems Inc - Why BACnet
		BACnet's capability to execute multiple read or write requests with a single command also gives it a throughput capability that is superior to many competing protocols, a factor that is often overlooked when network capabilities are compared.
		Since BACnet is being used on both networks, the router only has to transfer messages from one network to the other, it does not have to perform the more complicated task of translating one language to another.
		Providing BACnet communications at the field hardware level allows other BACnet devices (chillers, boilers, other manufacturer's controllers, etc.) to be integrated directly into the main control network and monitored by a single front-end software package, saving the expense and complexity of gateways.

		BACnet Web Services provide access to data in BACnet systems using standard PC desktop software instead of specialized drivers; they have also been proposed as the means of communications between energy utilities and BACnet systems for demand limiting and real-time pricing.
		BACnet was first published as an ANSI/ASHRAE standard in 1995 and is maintained under ASHRAE's procedures for "continuous maintenance." A revised version of the standard that included five previously approved addenda was published in 2001, and another revision including four additional addenda was published in 2004.
		BACnet has worldwide support and is maintained by a professional society under rules that provide open access and cannot be dominated by companies with particular commercial interests.

	BACnet - FAQ
		What makes BACnet special is that the rules relate specifically to the needs of building automation and control equipment, i.e., they cover things like how to ask for the value of a temperature, define a fan operating schedule, or send a pump status alarm.
		Because BACnet is based on a "client-server" model of the world, BACnet messages are called "service requests." A client machine sends a service request to a server machine that then performs the service and reports the result to the client.
		BACnet has been selected by the European Community's standards committee CEN TC247 as a European "pre-standard" meaning that it will undergo an evaluation process over the next couple of years to see whether it should become a full-fledged EC standard.

	PolarSoft® Inc.: BACnet Learning Center
		BACnet is literally a book that defines methods which a manufacturer can use, if it chooses to, to make systems which can be interoperable with other BACnet systems in various ways.
		BACnet achieves these goals by defining a generalized model of how automation systems work, and how to describe the information that they contain, and how to describe standard methods that one device may use to ask another device to perform some desired action.
		BACnet works by dividing the problem of interoperability into three distinct areas, and by defining methods and standards for implementing each.
