3. Workflow for troubleshooting (including
damage/emergency control)
• Workflow for troubleshooting (including damage/emergency
control) encompasses e.g. cases of:
– gas leakage detection confirmed by lower pressure of gas resolves in
opening windows in certain,
– or closing of their connections in earthquake situations,
– closing doors in contamination events detection,
– Others.

4. Roles of IoT and CPS concepts in digital
transformation in facility management
• The digitisation of buildings is here
• For example, one of the leading technical companies in Europe,
Siemens, says that building digitisation is here and data can be
leveraged to improve efficiency and drive down costs
• Internet of Things (IoT) and cyber-physical systems (CPS)
technologies can be applied to many application domains.
• Well-designed IoT/CPS can reduce energy consumption, enhance
safety in buildings and cities, or can increase the comfortability in
the building.

5. How IoT devices enable and support
predictive maintenance
• 5 ways Facility Management benefits from IoT:
1. Beacons enhance occupant interaction and workplace experience
2. IoT sensor infrastructure unlocks workspace optimisation opportunities
3. Optimising service efficiency with Activity Based Services
4. Taking maintenance to another level: from proactive to predictive maintenance
5. Improve indoor environmental monitoring, employee well-being and
productivity

6. Contemporary monitoring software and role in
predictive maintenance
• Facility managers in Intelligent buildings rely on BMS software to monitor
buildings and organize preventive maintenance.
• Examples include:

7. Example #1: Elevators predictive maintenance
• In the same way building occupants depend on functional
lighting and ventilation, they also depend on working
elevators in order to use their buildings effectively.
• Like lighting, ventilation and other building systems, the
elevator is getting smarter too.

8. Example #1: Elevators predictive maintenance
• New solution in monitoring elevators incorporates
cloud technology, machine learning and smart
sensors to offer real-time equipment health
information and advanced predictive maintenance
insights.
• Data from these devices are sent to the cloud where
it’s aggregated and analyzed in real-time.

9. Example #1: Elevators predictive maintenance
• Otis ONE leverages data from more
than 300,000 connected units to create
predictive insights and a more proactive
service solution for customers around
the world.
• “Data from Paris is fixing elevators in
Seoul”

10. Example #1: Elevators predictive maintenance
• Predictive maintenance is all about minimizing disruption to
the building, and when the algorithms suggest that a door may
need maintenance Otis can draw on elevator usage data to find
the best time for repairs.
• “Managers can now determine usage and if they have to
schedule a move and they can see that Tuesday afternoons
[have] the lightest usage.
• So they’ll have the least disruption by scheduling it for Tuesday
afternoon,” said Smith.

11. Monitoring software for elevator predictive
maintenance – example from Bosch
• Get insights from the elevators in building with
Bosch – Elevator Manager
– The number of high-rise buildings is rapidly growing
due to urbanization and the demand for more office
and living space. Elevators are a critical part of a multi-
story building’s infrastructure. In a bid to ensure their
safe and reliable functioning, facility managers face
many challenges ranging from the lack of operational
transparency to the shortage of skilled technicians [5].

12. Monitoring software for elevator predictive
maintenance – example from Bosch
• Get insights from the elevators in building with Bosch – Elevator
Manager
…
– Bosch effective end-to-end IoT solution for elevator monitoring puts
facility managers in control of their elevators’ operations and
maintenance. It provides valuable insights into elevators’ usage
patterns, allows to optimize their servicing, and helps prevent
breakdowns.
– The Elevator Manager is part of the Connected Building Solutions built
on top of the Bosch IoT Suite. This set of solutions delivers
comprehensive information on how the building’s infrastructure is
functioning straight to the hands of building owners and facility
managers [5].

13. Example #2: HVAC preventive maintenance
• Some of the routine maintenance perform
includes:
– Scheduled Filter Service – change filters and/or filter
media to improve indoor air quality and efficiency.
– Summer and winter checkups – align, calibrate, adjust
and lubricate HVAC units to extend equipment life and
ensure proper operating condition and efficiency.

14. Example #2: HVAC preventive maintenance
• Some of the routine maintenance perform
includes:
– Spring & fall startups – ensure proper operating
condition of heating or cooling and efficiency for the
upcoming season.
– Coil cleaning – concentrated pressure wash to unclog
the condenser coil of debris and improve cooling
efficiency.

15. Example #2: HVAC preventive maintenance
• HVAC Preventive Maintenance is Essential (6 Reasons
Why) [2]
• 1. Money Saving
– Here are ways preventive maintenance benefits:
• Prevent costly breakdowns
• Reduce energy bills
• Extend the life of your system
• Stay protected under warranty
– Regular HVAC maintenance is said to reduce the risk of costly
breakdowns by as much as 95%.

16. Example #2: HVAC preventive maintenance
• 2. Improved Air Quality
– There are reports that indoor levels of airborne
pollutants may be 2-5 times higher (in extreme cases
more than 100 times higher) than outdoor levels.
– This is particularly significant if building inhabitants
suffer from respiratory issues such as asthma.
– Generally speaking, preventive maintenance helps
ensure that the warm or cold air pumping through
your vents is as clean and well-filtered as possible.

18. Example #2: HVAC preventive maintenance
• 3. Improved Comfort
– HVAC systemkeeps tenants comfortable year round.
Regular maintenance helps systemproduce and
distribute the warm or cool air more evenly and
steadily.
– It can be easy to take maintenance for granted, or to
get used to the idea that a particular room is just too
hot in the summer or chilly in the winter. Preventive
steps like cleaning ductwork can help ensure that
building heats and cools as evenly and efficientlyas
possible.
– Regular maintenance will also minimize the chances
that HVAC noises or smells will disrupt quality of life.

19. Example #2: HVAC preventive maintenance
• 4. Keep Building Safer
– If tenants are away from home and heat stopsworking
during a cold snap, the result can be a domino effect of
frozen or burst pipes, water damage and worse. The cost
of repairs in this situation can be incredibly steep.
– Preventive HVAC maintenance also helps safeguard you
and your family against the risk of carbon monoxide – the
colorless, odorless gas whose effects can be deadly.
Exposure to even low levels of carbon monoxide can
cause serious health issues.
– The most common cause of carbon monoxide leaks is a
cracked or failed heat exchanger. An HVAC maintenance
checkup typically includes a carbon monoxide test that
would detect any potential hazard, with special benefits
of installing a carbon monoxide detector.

20. Example #2: HVAC preventive maintenance
• 5. Environmental Protection
– Well-maintained HVAC systemconsumes
considerably less fuel – and that’s good for the
planet.
– HVAC technicians handling controlled refrigerant are
required to have certification and can help regarding
what kind of refrigerant is used, its impact on the
environment, and the options.
– HVAC contractor can also talk about the benefits of
using a programmable thermostat or switching from
oil heat to natural gas so to reduce system’simpact
on the environment.

21. Example #2: HVAC preventive maintenance
• 6. Giving Greater Peace of Mind
– Finally, preventive maintenance plan gives the
comfort of knowing that if something goes
wrong, steps to make the situation as painless as
possible have already been taken. https://pixabay.com/photos/air-conditioning-
