The purpose of preventive and predictive
maintenance
• Maintenance represents the bulk of
the costs occurring in a building’s
life.
• The advent of smart technologies
can lessen this financial burden.
• Smart Buildings are also elevated to
the Next Level of comfort and
safety with Predictive Maintenance.

proactive-smart-building-technology

Maintenance vs. construction costs
• In the life cycle of a building, maintenance costs largely
exceed the construction costs.
• Buildings consume 40% of global energy and produce
36% of greenhouse gas emissions.
• EU targets have not been achieved (gap of 10-30%).
• 5-20% of energy consumed in buildings for HVAC,
lighting, water heating is wasted due to faults and
inefficiencies [1].

The purpose maintenance
• Actually, maintenance is a strategic activity in
buildings and smart buildings as well.
• A sound planning that starts right from the
design stage is very important to ensure the
economic sustainability of future interventions. https://pixabay.com/photos/plumbing-pipe-

maintenance
• For example, in Italy between 2014 and 2015, the cost of ordinary and
extraordinary maintenance works was around €117 billion while the
construction sector was worth €169 billion.
• Safeguarding existing stock was therefore equal to 70% of the building
sector’s entire turnover [2].

maintenance
• Modern buildings can gather millions of data
points that capture real-time information about
occupancy, temperature, humidity, and air quality
among many other measures.
• Intelligent data analytics empower these
buildings to make occupants more comfortable
and productive at the lowest cost, while
managing energy and operations more efficiently.

maintenance
• But that's just part of the story.
• By applying the right set of tools, powerful insights
can be obtained from the vast amount of data
garnered from a building.
• We can see patterns, we can build a model, and we
can predict.
• Building management can be made predictive and
proactive!

internet-online-www-3808483/

The impact of smart technologies on
maintenance costs
• Innovative technologies in smart buildings
drastically reduce operating and maintenance
costs thanks to their ability to collect and
analyse data, which previously was
unattainable.
• In addition, sensors placed on equipment can
automatically programme maintenance
activities, which are therefore based on use
rather than pre-scheduled intervals.

keyboard-mouse-big-data-4165393/

The impact of smart technologies on
maintenance costs
• Predictive maintenance is 3 to 9 times cheaper
than a reactive approach,traditionally achieved
when the damage has already occurred.
• Moreover, with smart building management
technologies, owners are informed of potential
problems before the equipment actually fails.

investment-business-2724241/

Who will deal with smart building maintenance?
• Occupants have little role in the maintenance,
not even in reporting the faults. The process is
completely automated and any issue is solved
before the occupantsrealise it.
• Moreover, the technicians involved in the
intervention on the building will not waste time
looking for information to fix the problem.
https://pixabay.com/illustrations/electrician-
job-maintenance-4423534/

• Thanks to thermography or infrared scanning,
for example, a building manager will be able to
detect any device running outside the
temperature range.
• This data can be easily detected in advance, so
that maintenance can be performed before the
equipment interrupts the system.

• Another example is the detection by ultrasound.
Electric transmission lines, which have slots or
holes, produce ultrasounds.
• This can go unnoticed in normal cases, but with
IoT technology, technicians can easily identify the
exact location that needs the maintenance
intervention [3].

• Having said that, it is also true that the success
factor in a technologicalinnovation lies in the
degree of acceptance by users, who can perceive
it as a "threat" affecting their daily life.
• It’s therefore important to involve users early on
and to familiarise them with the smart
technology to be implemented.

Facility Assessments
• There are two ways to assess a facility’s needs
to proactively prepare for and manage future
issues.
– The first, the old one, is by relying on the
knowledge and prior experience of the facility
manager.
– The facility manager knows the building, walks
the halls, and has equipment records to know
when the assets were first installed, their
expected life, frequency of maintenance, when
and why they last failed, and what repairs or
maintenance needs may have been deferred.

• There are two ways to assess a facility’s
needs to proactively prepare for and
manage future issues.
– Facility managers know the buildings better
than anyone else, understanding the
strengths and weaknesses of their
portfolio, and may have a good idea on
what’s in the immediate future for asset
performance.

manager-2874597/

• There are two ways to assess a
facility’s needs to proactively prepare
for and manage future issues.
– A secondmethod for accurately
measuring the needs of a facility is to
conduct a facilities condition audit.
– Some organizations are required for
perform audits periodically. An audit gives
facility managers a thorough
understanding of the major equipment
and systems in the building portfolio.

• There are two ways to assess a facility’s needs
to proactively prepare for and manage future
issues.
– The outcome of the audit will help managers
identify future needs, schedule upcoming
projects, and prioritize the projects using the data
accumulated during the audit.
– Audits help facility managers establish a baseline
to compare one facility’s condition against
another, and measure maintenance effectiveness.
– Perhaps most important of all, a facilities
condition audit helps facility managers develop
both long and short term budgets, taking into
account the future needs identified from the
audit.

Digital transformation in facility management:
a major role for smart buildings and
big data analytics
• Just like in virtually all professional
activities and industries,there is a digital
transformation sweeping through facility
management and as seen the Internet of
Things, plays an important role in it from a
technology and purpose (people, place,
safety, process, automation,insights and
action, efficiency,…..) perspective.

How IoT Devices Enable Predictive
Maintenance
• Internet of Things-enabled monitoring system
typically includes three components:
– Sensors will collect measurements from equipment
and record ambient conditions.
– A data logging or networking devicewill intercept
the streams of data from of the sensors and
aggregate them in a central location.
– A dashboard or other interface will interpret the
data and help you prioritize what to act on first.
https://pixabay.com/illustrations/monitor-binary-
binary-system-1307227/

How IoT Devices Enable Predictive
Maintenance
• There are also a number of conditions for
equipment that can be monitored with IoT
devices.
• For example:
– Is a piece of equipment on or off?
– How fast or hard is a drive running?
• On the environmental side, using the
Internet of Things is suggested to measure
temperature, carbon dioxide or particulate
matter.

• Humans and buildings: Connected to work
together
– Digital transformation is having a far-reaching
and already visible impact on our working
world and the environment in the buildings we
work in.
– With so many assets,extensive technologies,
increasingly sophisticatedsystemlandscapes
and complex data, facility managers are
inundated with information – which poses new
challenges.

• Humans and buildings: Connected to work together
…
– On top of previous, companies want easier-to-manage
buildings that perform better while delivering greater
energy efficiency.
– One way to achieve this is to connect buildings so they
can interact with humans.
– If we link up building technology and sensors, and
collect their data at a central point, we can analyze this
information to gain new insights.
– With this knowledge, we can optimize building
operations, come up with new value-creation
processes, and make building management a whole lot
easier.
