We
understand that building data is our future but the
myriad of diverse devices all speak different dialects of an
undocumented language.
Cloud Databases are becoming common ground but without preprocessing, data complexity exists.
Is the solution an application program interface (API)? A set of
functions and procedures allowing the creation of applications that
access the features or data of an operating system, application, or
other services?
Scott Cochrane, President and CEO Cochrane Supply & Engineering Contributing Editor shares his observations in this article:
API = New Software & (Integrator) Capabilities x Infinity!
BUT… it’s just not that simple. As you can imagine, it brings new
challenges for the integrators for normalizing data from these unique
new IP systems so they can incorporate the new tech occupant
experiences while still providing the comfort, safety and security for
the buildings they serve. Frankly, BACnet IP just doesn’t
cut it. Why? Because BACnet IP doesn’t have all of the information
needed to properly integrate the application being served. BACnet is
valuable for BAS data and will continue to be, but IP networks are
super dynamic, always challenging, and never the same in two buildings.
As a result, we will need more from IP controllers and devices to be
able to deliver the next level occupant services and be in harmony with
the networks we now live on. Enter the API. (Or Application
Programming Interface.) Devices that come with a documented rich
APIs are the open solutions of the future
And then follows with
The Call Home Strategy - Yes, Another Building Data Story…
As we continue to see cloud-based solutions deployed in buildings, we
have stumbled upon what may be a future industry in itself. How
does the digital device/system share its data, commands, logic,
everything???? from inside a building to an on/off-prem cloud? We
call this a product or system Call Home Strategy. With more and
more IP devices flooding the market, many are coming with remarkable
cloud-based services that set the product capabilities on fire.
There are way too many cloud advantages to hard line into an
on-prem-only policy for all building control systems. Even the
most secure systems in the most secure buildings need software updates
to maintain their highest level of cybersecurity, which often requires
a download from a cloud. In past years, we considered this remote
access. But, with the advent of IP devices with attached cloud services
(like a Wi-Fi stat for your house), this becomes much more complicated
than just setting up a VPN into a remote network.
So why do we need a call home strategy? IT’S ALREADY HERE!!! We
are already supporting all sorts of call home strategies for building
control systems and new products, many of which are well tested and
working great. BAS is not the only industry engaged—life safety
and security products are coming with these capabilities as well, which
means it’s here to stay. The BUILDING OWNERS are READY for this change
in their industrial commercial properties, but they have complicated IT
environments with way too many digital devices to control. As a result,
the need for an adjustable, comprehensive, cyber secure, managed cloud
connection is in demand and will forever change the landscape for
controlling buildings.
Benefits of Cloud Connected Buildings
Adopters of cloud computing such as building owners or end users,
however, may need to know what the cloud can do to improve building
operation and occupant conditions. Insight is provided in this article

The Edge and the Cloud complement each other. Building automation
equipment can be connected to the cloud in several different ways. The
most straight-forward approach is to use Edge controllers. Edge
controllers communicate with the local operational network and
supervisory stations using common protocols such as BACnet or Modbus.
They are installed on the Edge of the IP network (hence their name)
behind a firewall to reduce network attack surface. Edge controllers
usually have built-in I/O and a programmable or pre-programmed sequence
of operation to control mechanical equipment at the site. By leveraging
open IoT protocols such as MQTT, proven security mechanisms such as
Transport Layer Security (TLS), and robust software as a service
solutions (SaaS) such as Azure IoT Central, Edge controllers can easily
and securely connect to the cloud, effectively making any attached
equipment a cloud connected asset.
The Edge
The New Building Mindset - Marc Petock, Chief Marketing &
Communications Officer, Lynxspring, Inc. Contributing Editor
Marc adds The Edge is becoming an integral part of many organizations
building operational strategies. Building owners and operators are
looking for faster, real-time analysis of the massive volumes of data
produced by equipment systems and devices to improve operational
decision-making. It can now be said that the data produced from a
device is now more valuable than the cost of the device. We are
connecting more devices and crunching more data more quickly than ever
before. The Edge is here, and it is here now.
Christopher Naismith of http://www.audette.io/

http://sesconsulting.com/ research and development team provides these thoughts,
There's a lot of discussion about having everything 'talking the same
language' and while standardizing is important, diversity is part and
parcel of innovation. Things spring up out of different places
with different philosophies, some better than others but none
necessarily the best. The way this is handled in the software as
a service space is that an application will have a documented API with
a set of instructions that describe how to GET and POST data to that
application. This allows developers to interface directly
with the program in a predefined way. Not being in computer
science, I don't know of the drawbacks to this method, but it certainly
makes development a lot faster and smoother. I don't have to use
the same code or same software 'stack' as another application, but I
can still access important bits of information from its database as
needed. This also allows services like Zapier and IFTTT to act as
the 'translation engine' between applications so as a consumer I don't
have to petition developers of either application to develop
anything. I can connect my thermostat to my front door lock even
though the apps don't have a native integration.
Our contributing editor Brad White provides the following thoughts,
This definitely came up in
our discussions on open systems last year as part of AHRExpo Atlanta,
The group of us pretty much agreed that in the future, "Open" didn't
necessarily mean fully open source or open protocols (though it could)
but also extended to things like open APIs that allowed for
interoperability. I'm sure like anything, APIs are not created equal,
and standards are needed to ensure an appropriate level of
interoperability, maybe this is where REST comes in, I'm not sure. I
know that the APIs we already use on a daily basis have frustrating
restrictions on what you can and cannot access via the API, and of
course, that could change at any time. This is where true open-source
proponents will say that because of this, you can't say that APIs are
really open. Nevertheless, seems almost inevitable given that's how
most web services already interact.
Diverse Service Models are the Key to Delivering the Benefits of Analytics - John Petze, C.E.M., Partner, SkyFoundry
John writes Analytics is proven, and it can be very easy to get started.
Start by asking “what data do you already have available?” – in other
words, data that is available at low, or no cost. Then take the next
step to define a manageable project scope to apply analytics to that
data to derive value from it. Data really is the new money if you know
how to use it.
IoT Meets Building Automation
IoT is advancing building automation beyond mere optimizations. It's
bringing systems together and adding new value, through innovations
like demand control and the way it improves air quality. But we must
remember that IoT-based analytics platforms work only because they
connect people with technology—without humans at the helm, they’re of
little value.
