Since 1987 the American Society of Heating and Refrigeration Engineers has lead development of the de facto standard for campus building automation systems 135 BACnet® – A Data Communication Protocol for Building Automation and Control Networks. This title supports the #WiseCampus transformation in two important ways:

• It defines data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems
• It defines an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

BACNet Committee: ASHRAE SSPC 135

Since the late 1970’s these systems have grown from single building control networks for environment air into multi-building campus-wide systems that conform to the ISO model of layered communication architecture.   Every large research university has long since installed facility management unit that monitors and controls points such as outdoor air intake, wet-bulb temperature, occupancy load, elevator action, time of day, outdoor lighting etc.    The University of Michigan, for example, monitors and controls nearly 1 million control points on its 6 square mile Ann Arbor campus.

The ASHRAE 135 technical committee has released a consultation on addendum cd regarding cipher suite application security profiles.  Several redlines are now open for public consultation and may be found here:

ASHRAE Public Review Drafts Standards

Consultation on several titles is open until March 20th.

This title, and several others in the ASHRAE catalog, are on the standing agenda of our Energy 200 and Energy 400 colloquium.  See our CALENDAR for the next online meeting; open to everyone.
