Connect can increase cybersecurity
of products that use the protocol.
The purpose of BACnet SC is to provide encrypted secure data between
nodes, which is rapidly becoming of
signiﬁcant value to building owners, said Andy McMillan, Associate
Member ASHRAE, president and
managing director of BACnet
International.
"So what we want to do is ensure
the rapid availability of BACnet SC
across a broad range of products.
Because you need to implement it
across your system," he said.
BACnet SC is an additional
data link option in BACnet, said
McMillan, adding "it's the same
BACnet." BACnet users can pick
between IP and MS/TP as two different ways to transport data. Secure
Connect is another option to transport data, he said. The implementation is not extreme, and people who

90 Years of
Innovation and
Counting

Ninety years have passed since
the ﬁrst incarnation of the
AHR Expo. And the Show and
its ever-changing innovations
are showing no signs of stopping. The ﬁrst International
Heating and Ventilating Exposition opened in Philadelphia
during the last week of January
in 1930, a few months after
the Wall Street Crash of 1929.
This year, the 72nd edition of
AHR Expo showcased the newest technologies and kept the
tradition of bridging the gap
between industry needs and
innovative solutions.

Visitors explored thousands of products in more than 770 categories.

already have BACnet products can
move to BACnet SC by working on
that one layer.
"Everything else stays the same,
and everything else is interoperable
and all that good stuff you want," he
said.
BACnet International is speeding
up the adoption and implementation by helping suppliers learn
what they need to know for implementation, said McMillan. Like
other software, it can be designed
differently, so having experts implement BACnet SC in a reference
implementation that all the participants can see and comment on the
source code is beneﬁcial. Experts
will explain why the protocol was
designed certain ways to help suppliers, McMillan said, which will
help increase understanding and
reduce backtracking when the suppliers implement the protocol.

Evolving Expectations
Technologies in the residential and
commercial sectors are informing
each other. More commercial spaces
are adopting home automation techniques such as smart thermostats

and voice control integrations, said
Tom Rule, business line manager
for building automation software at
Siemens.
Another example of the residential
sector inﬂuencing the commercial
sector could be what happens as several U.S. states and other countries
move away from using fossil fuels.
"At the state level, across the
country, we are seeing a snowball
effect in the move away from fossil
fuels. Talk around the concern on
fossil fuels has been replaced with
action and innovation," said Kevin
McNamara, senior vice president
and general manager for LG Air
Conditioning Technologies.
Berkeley, Calif., is a prime example of this movement. Starting in
January 2020, the city requires all
new buildings to be all-electric
with no natural gas hook-ups, said
Kyle DelPiano, Associate Member
ASHRAE, who is a business development manager for commercial
building systems at Xylem.
Over 50 cities and counties across
California have or are considering
policies to support all-electric new
construction. While the trend to
