BACnet®, the ASHRAE building automation and control networking protocol
BACnet, the ASHRAE building automation and control networking protocol, 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; fire and other life safety and security systems; energy management; lighting control; physical access control; and elevator monitoring 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 mobile and cloud-hosted devices, 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 building automation data between devices including, but not limited to
(a) hardware binary input and output values,
(b) hardware analog input and output values,
(c) software data values,
(d) schedule information,
(e) alarm and event information,
(f) trend and event logs,
(h) control logic,
(i) application specific data for a large range of building services, and
(j) network configuration including security.
Standard 135-2016 -- 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 an abstract, object-oriented representation of information communicated between such equipment.

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
