TECHNICAL FEATURE
Conclusion
In two articles, we aimed to investigate and
document (1) what metadata and metadata schemas
mean in the context of smart buildings, where one
can fi nd such metadata and (2) what the added value
of these metadata are for smart buildings and control
algorithms in those smart buildings. In terms of
this value proposition, we pointed out three areas
where these metadata add value, namely in making,
running and engineering the models in control of the
smart building.
While metadata play a role in making and running
a smart building, the added value perhaps lies even
more in the engineering phase of creating a smart
building. As indicated in this article, this relates to
four points of value: (1) suffi cient self-description
of systems, (2) structural context, (3) holistic
building and system diagnosis and (4) potential
for generalization. Especially in combination with
suffi ciently separated metadata descriptions (late
binding), control algorithms in smart buildings are
expected to become more portable from one building
to the other.
All in all, this provides two main important and
tangible value propositions for the smart building
industry: (1) to achieve increased effectiveness and
time gain in engineering a smart building control
strategy and (2) to provide the possibility and
opportunity to allow for multiple solution providers to
work in parallel and upon each other within the same
data framework.
