Content DescriptionMeet Building Automation and Control Systems Communication Needs with Standard 135-2012 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, 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. 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 2012 publication of the standard was motivated by the wide-reaching changes in alarming functionality made by Addendum af to Standard 135-2010. This edition of the standard also includes the recently adopted changes for the lighting industry.This book also exists in the following packages...Subscription InformationMADCAD.com ASHRAE subscriptions are annual and access is concurrency based (number of people that can access the subscription at any given time).

About ASHRAEASHRAE, founded in 1894, is a building technology society with more than 50,000 members worldwide. The Society and its members focus on building systems, energy efficiency, indoor air quality and sustainability within the industry. Through research, standards writing, publishing and continuing education, ASHRAE shapes tomorrow’s built environment today.
ASHRAE was formed as the American Society of Heating, Refrigerating and Air-Conditioning Engineers by the merger in 1959 of American Society of Heating and Air-Conditioning Engineers (ASHAE) founded in 1894 and The American Society of Refrigerating Engineers (ASRE) founded in 1904.
