BACnet can seem pretty
complicated to an outsider (by which I mean
people who are not intimately involved in BACnet-related activity) … or
it can seem very simple. The reality is that it is both
complicated and simple, depending on how you look at it. From a
technical perspective it is complex because it has to address a wide
range of communications issues across a very large set of
circumstances. From a business perspective, though, BACnet is not
so complicated. Unfortunately, most of the information available
about BACnet is either addressed to a technical audience or reads like
it should have been. Recognizing this problem, BACnet
International continues to work on building a set of resources that
will give building owners and operators more generally useful
information about BACnet. Some recent results of this effort are
the “BACnet Made Simple” webinar presented in
collaboration with
Building Operating Management magazine in June, the expansion of the
BACnet International Journal and the 2011 BACnet
International
Conference and Expo to be held in conjunction with the October 11-12
Facility Decisions conference in Las Vegas.
Communication Complexity
There are plenty of ways a person can get lost in the complexity of
the technical information surrounding BACnet, and the biggest culprit is the
specification itself. And, I do mean “BIG.” The document
with all its components is huge. Even more challenging is that
it’s written by technical people for technical people. The
acronyms alone would make it incomprehensible to outsiders (and many
insiders). To make matters worse, outsiders usually ask
technical people to explain BACnet – which can create more confusion
than clarity. It’s sort of like asking an automotive engineer
to explain the difference between a five-speed transmission and a
four-speed transmission. They are likely to explain it in terms
of torque, brake-horsepower and gear ratios when all you really need to
know is that the five-speed will give the car more power at low speeds
and better gas mileage at high speeds. The solution to this
problem is to leave the specification to technical folks and present
BACnet to outsiders in terms of benefits, features, functions and
concrete examples. BACnet International is focused on doing
exactly that.
BACnet Webinar
The “BACnet Made Simple” webinar was designed to present the business
case for BACnet to non-technical people in a way they can understand
its value as well as its limitations. The result is a
presentation where any reference to BACnet technical language (such as
Objects, Properties, Services, BIBBs, and PDUs) is largely to point out
that it’s not necessary to learn them in order to grasp the essence of
BACnet’s importance and application. The webinar is focused
instead on the value of using BACnet effectively. It describes
the difference between early (expensive) approaches to multivendor
systems and the BACnet smart systems approach. It explains the
concept of smart systems and shows exactly how BACnet lowers the cost
of system implementation. Finally, the webinar includes an
audience question and answer session. The webinar is one path for
getting to the basics of the BACnet business case.
BACnet Business Case Resources
Another path to build understanding of the BACnet world is the 2011
BACnet International Conference and Expo. It will be held in
conjunction with Facility Decisions in Las Vegas, October 11-12.
Like the webinar, the conference has been designed to present BACnet to
people who are more interested in building value for their
organizations than getting involved in the technical details of the
BACnet specification. I have been asked to present the opening
session at the conference and you can expect that open systems, the
role of IT in connected buildings and the concrete benefits of BACnet
solutions (all favorite topics of mine) will find their way into that
presentation. In addition, the conference will present a wealth
of real-world application experience in a variety of
presentations.

Of course you don’t have to wait for the conference to effectively
navigate BACnet information resources – just visit the BACnet
International website. To keep current on developments as we
count down to the conference you can also join the BACnet International
group on LinkedIn. Another option is to review the presentations
from last year’s conference, including BACnet Fundamentals and BACnet
puts the M in EMS. In addition, BACnet International has
assembled a series of success stories to help building owners and
operators get started. There are over 25 case studies on BACnet
projects available for review.
Summary
I am often asked how outsiders can successfully enter the world of
BACnet. I regularly point out that forcing outsiders to learn the
insider world is slow, painful and likely to lead to
misunderstandings. Instead, we need to demystify BACnet. We
need to make is easy for people interested in the business of BACnet to
learn what they need to know without becoming technical experts.
We still have a ways to go, but we have begun to address that need
through focused resources and a lot of great volunteer effort.
And we will continue to work on it. You can expect to see more
BACnet International sponsored webinars in our future and a continued
focus on electronic and print publications. In the meantime, you
can take a couple of easy steps by checking out the “BACnet Made Simple” webinar and joining us at the 2011 BACnet International
Conference and Expo.
