BACnet®, the ASHRAE building automation and control networking protocol
BACnet® has been designed specifically to meet the communication needs
of building automation and control systems for applications such as
heating, ventilating, and air-conditioning control, lighting control,
access control, and fire detection systems.
The BACnet® protocol provides mechanisms by which computerized equipment of arbitrary function may exchange information, regardless of the particular building service it performs. As a result, the BACnet protocol may be used by head-end computers, general-purpose direct digital controllers, and application specific or unitary controllers with equal effect.
This protocol provides a comprehensive set of messages for conveying encoded binary, analog, and alphanumeric data between devices including, but not limited to:
(a) hardware binary input and output values,
(b) hardware analog input and output values,
(c) software binary and analog values,
(d) text string values,
(e) schedule information,
(f) alarm and event information,
(g) files, and
(h) control logic
Standard 135-2012 -- BACnet®--A Data Communication Protocol for Building Automation and Control Networks
The purpose of Standard 135 is to define data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems and to define, in addition, an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

This new book by H. Michael Newman, original chairman of the BACnet committee, explains how the BACnet protocol manages all basic building functions in a seamless, integrated way.
The book explains how BACnet works with all major control systems--including those of Honeywell, Siemens and Johnson Controls--to manage everything from heating to ventilation to lighting to fire control and alarm systems. Contractors, architects, building systems engineers and facilities managers must all be cognizant of BACnet and its applications. Learn more
