|One Protocol to Rule them all?
Taking buildings to the cloud, connected buildings, advanced analytics, machine learning, Internet of things… How do we get value out of buildings in the best way possible that is also future proof? Is there such a way?
The Handshake-Problem with the
doesn’t have to be complicated, so I will try to simplify things,
starting with the API-economy. There’s a lot of data in buildings, and
there’s a lot of opportunities to make sense of the data, do analytics
on it and to create new services for people working with buildings. To
get the data out usually you must have an interface, an API of sorts.
Making buildings talk to people is, after all, the one thing that I try
to help out with.
An API is basically like defined handshake. I have my defined handshake, you might have yours, and if we were to shake hands, we'd face a couple of different options which are described here. The definition of an API is an Application Programming Interface. Simply put, it is a defined handshake which will make the process of making handshakes into something that will at least be easier than without a defined API. But it won’t solve everything, far from it. It might make things worse in the long run. Not necessarily, but it might.
Let’s go through a couple of scenarios.
We don’t have any defined APIs
we don’t have any defined APIs, it will be difficult for us to shake
hands because we don’t even know how we could shake hands. And if
someone else wanted us to shake hands, they would have a really hard
time figuring out how we could shake hands because they might not have
a good idea to what languages we are talking or if we even want to
The first step would be to get APIs = the possibility to shake hands in a defined way and not lock in the data, hoping that will make us irreplaceable.
We have an APIs, but they are not the same
now have our own handshakes, but they are not the same. Who wants to
initiate the handshake? Let’s say that one side wants to shake hands;
then they will have to figure out how to do it. They can change their
handshake to fit the other one’s handshake or also create something in
between where the handshaking will take place. This might be anything
but simple or difficult, but it adds complexity, and it will take time.
Let’s say you walk into a room with 20 different APIs. 20 people with different handshakes, and for every person you need to figure out what is in their handshake and how you should approach it. That will take time, effort and as we’ll describe later, it will only be 1% of the effort needed in getting to the complete solution.
We have an APIs, and they are the same
now have our own handshakes, and they have been defined in the same way
as our counterpart. We can now rest assured that things will be easier
moving forward. However, the handshake is only the first part. It
doesn’t mean that we speak the same languages. It doesn’t mean that we
have the same values. It doesn’t really say much of how we can talk to
each other, the effort it takes to talk to each other and also what
language we should use in talking to each other.
Imagine this at scale.
We are in the same room. We all want to talk to each other, but we have different definitions of the same things. Or we have different definitions of different things. We speak in different languages. And everything about what we do, how we do it, is totally different. We come from different worlds, but somehow, someone came up with the idea that we are going to act like one just because we share the same definition of a handshake. And someone else out there expects that it is the outcome of us working together that is the amazing thing.
Culture eats strategy for breakfast
Basically, this is a cultural question which relates to us people as well. Consider a merger between two companies where the culture is different even though everything else stays the same. This will be problematic and as we all know Culture eats strategy for breakfast.
is not far-fetched to compare the definition of culture and values to
that of semantic interoperability between systems considering that
definition of culture is:
“The customary beliefs, social forms, and material traits of a racial, religious, or social group.”
“the characteristic features of everyday existence (such as diversions or a way of life) shared by people in a place or time.”
And semantic interoperability:
“Semantic interoperability is the ability of computer systems to exchange data with unambiguous, shared meaning. Semantic interoperability is a requirement to enable computable machine logic, inferencing, knowledge discovery, and data federation between information systems.”
Semantic interoperability leaves little to no doubt as to what is inferred. Whereas cultural norms and values would be more open to interpretation. However, both play the vital role of acting as a mediator between two or more otherwise interoperable areas what could be important boundary spanning elements and possible definitions of a subset of the ANT-theory by Bruno Latour.
And as such, an important piece when trying to make different things come together to make things happen in a better, future-proof way.
A shared set of values is the key
handshake is nothing but a handshake. It is what comes after which is
the most important and exciting part. Thinking that the outcome of the
merger will lead to amazing results just because you shake hands with
the other company is exactly the same thing that is happening right now
out there in the world of IoT. It won’t really bode well.
“According to McKinsey research, only 16% of merger reorgs fully deliver their objectives in the planned time, 41% take longer than expected, and in 10% of cases, the reorg actually harms the newly-formed organization.” – HBR
merger is after all a clash of two systems with their own set of
standardized definitions and ways of working. Just making them shake
hands won’t make them work. Far from it.
“…You will have to choose one structure that integrates the two companies.”
Replace companies with systems, and the two companies mentioned might not be two companies but a merger of 10 companies, i.e., Systems.
If I say tree, what do you think of?
I think about a Christmas tree.
And when I say Christmas tree, what do you think about?
• What is the size?
• What is the location?
• Does it have a star at the top?
• What’s the color of the star?
• The material of the star?
It doesn’t say anything else about anything really because we haven’t got shared definitions and boxes of what should be included about what a tree is. It is partly to define the size of the boxes and what they are and a part where we can standardize a subset of an industry with the same tagging conventions/standards.
I could write 30 more pages on this matter but let’s move on to the final remarks…
Artificial Intelligence and Machine learning needs more than a handshake
truth is that most of the analytics efforts out there today are spent
on 80-90% cleaning of data. And 10-20% on the part where the value gets
derived. So, this is an immediate problem that needs to be solved to
leverage existing data with Artificial Intelligence and Machine
Learning. This is crucial for us to really make sense of the data and
to achieve results never before possible.
The problem within the building automation sphere is not that big in comparison to other fields. And why is that?
The solution to all of these problems
discussed, APIs are a good start but don’t get fooled in thinking that
the API economy is the end of all of our problems. As discussed over
and over again (It’s important!) it might actually be the exact
opposite and the beginning of a whole new set of problems as depicted
The answer lies in standardized protocols which can harmonize data from different vendors, acting as a device to device communication protocol.
Semantic interoperability, and how to solve this issue will be of major importance moving forward. Consider it as the rule book when having made a merger and how everyone should work.
It is here Haystack tagging comes in, and where BACnet will play a major role moving forward and as we have said before, BACnet might be renamed to BACnet/IoT soon enough!
BACnet is the standardized bowl filled with pockets to fill with an industry-specific standard and IoT solutions. But the bowl and the BACnet objects within the protocol is what is needed, and luckily we seem to be well on our way in realizing this for the betterment of all buildings and cities out there. The problem is not that big within the building automation sphere, yet. But with the advent of unstructured data coming in from the sides, we are bound to have a lot of challenges moving forward.
Because BACnet and upcoming addendums solve that pretty well, providing a standardized platform for others to build on.
Final words – Focusing on the outcomes
For others to build on, that is the important part.
Using BACnet as the protocol layer for everything is, in my opinion,
the key in transforming data to information when making both buildings
and cities “Go-IoT” and Cloud ready.
Connor McCloud might be angry at me for writing this, but there won’t
be the only one solution out there. And that is how it should be. There
won’t be one solution to rule them all, and what we should strive for
is open standards, service transparency and the creation of true
Digital Twins for the betterment of others. I might think that BACnet
is the solutions to rule them all, but it is the outcome we all should
collaborate towards. I’m in it to create a better world for everyone
with smarter, more energy efficient buildings. Fewer costs and headache
for maintenance and above all, better indoor climate, personalized
experiences for tenants and users of buildings worldwide.
In order to make buildings talk to people, we need to understand what
they are saying. And luckily, we are well on our way!
