Case Study
Executive Summary
The Solution
Honeywell is evolving its Service
offering to focus on translating client
KPIs to improved and tangible results.
The new offering, Outcome Based
Service utilises analytics to drive
optimised building performance.
Outcome Based Service
monitors your building
24/7 and therefore provides
robust fault identification.
Sensors and set points
report back continuously
helping systems operate at
optimal conditions and faulty
sensors can be identified.
The enhanced fault finding
capability reduces unnecessary
plant operation and therefore
helps boost energy savings,
reduce running costs, and
increases the longevity of plant.
By monitoring sensors and
conditions more closely, the
building will provide a better
internal environment and
improve occupant satisfaction.

Outcome Based Service versus Planned Maintenance
Outcome Based Service is the next generation of Honeywell Service offering.
Planned Maintenance (PM) is focused on the regular inspection of building
assets on a fixed schedule. These schedules could be adapted as required.
However, their fixed nature meant that equipment was inspected regardless of
whether there were current or anticipated problems.
Outcome Based Service makes extensive use of automated building monitoring
and analytics. By monitoring and analysing building performance 24/7, we are
able to:
• Develop tangible
maintenance KPIs that
drive outcomes which are
important to our customers
• Move to a flexible
maintenance schedule that
focuses on maintaining
overall performance.

Rather than ensuring that a specific asset is visited a pre-determined number
of times, Outcome Based Service focuses on the goals of comfort conditions
being met, energy targets being achieved, and the right dynamic balance
being struck between ongoing performance optimisation and reactive
maintenance works.
In our Outcome Based Service trial, technical staff were able to identify a
much larger range of potential problems and evaluate them significantly
faster, reducing the impact on the performance of the building.
Outcome Based Service –
The Facts
Honeywell has undertaken a significant
research and development effort in order
to design, implement, and successfully
validate the new approach at a commercial
office tower in Melbourne Australia.
Using a suite of fine-tuned algorithms to
monitor the air side system, our service
team was able to scrutinize these building
assets 24/7, identifying multiple faults
and misconfigurations ahead of schedule
and lay the groundwork for a system that
will achieve what is truly important to the
building owners-occupant satisfaction
and enhanced energy efficiency.
The Trial and its Findings
Honeywell completed a one month trial of Outcome Based Service across four
floors of a commercial building, focusing on air side systems and occupant
comfort. The focus was placed on the air side systems, given their importance
in achieving occupant comfort.
During the trial, maintenance was carried out in two ways, i.e. using the
traditional PM and new Outcome Based Service methodology. This allowed
us to test whether the new method captured all the potential issues that were
identified using the traditional service model.
The following outcomes were achieved:
The new service model driven by Outcome Based Service, makes extensive
use of automated building monitoring and analytics. The 24/7 monitoring and
analysis of building performance achieved the following:
• A number of faulty sensors were identified ahead of schedule; these would
have only been picked up during the next maintenance cycle in a number
of months.
• Various assets were identified that were left in manual mode.
• Optimization opportunities for economy cycle operations were identified
which will lead to reduced energy consumption.
• VAV boxes leaking airflow were found which lead to increased energy
consumption and potential reduction in occupant comfort.

The trial showed that Outcome Based Service is capable of delivering a superior
picture of the current building performance as compared to traditional planned
maintenance. It promotes improved fault identification and impact assessment
to better support customer outcomes.
A Revolution in Service
Honeywell Outcome Based Service
is a truly revolutionary change in
the way servicing is conducted,
helping save time and money and
improve building performance.
The Revolution –What does the new service approach look like?
The Benefits
Traditional maintenance service revolves around fixed schedules; a method
that will naturally lead to delayed rectification of problems and premature
maintenance of equipment that still shows acceptable performance.
Outcome Based Service addresses these optimization opportunities by
utilizing building analytics to monitor assets 24/7. This continuous monitoring
allows Honeywell to align our actions with customer KPIs rather than to the
adherence to fixed schedules:
• Focus on maintaining comfort conditions.

At the heart of the approach is alignment to your outcomes and KPIs driving what Honeywell focuses on and how we keep you informed.
• Optimize plant life cycle and promote optimal balance of operation costs
and capital cost.
As shown in the comparison below, problems are fixed as they occur rather
than according to a predefined schedule:

Balancing reactive and
planned costs
• For any target performance
outcome, there will be an optimum
balance between planned and
reactive maintenance efforts.
• Outcome Based Service will assist in
finding this ‘sweet spot’ that delivers
desired outcomes at the lowest cost.
By analysing the asset performance
data, Honeywell will be able to help
optimise budget allocations across
operational functions and also
advise on the value assessment of
potential new capital outlays.

The Analytics
Outcome Based Service is driven by building analytics which lends itself
to graphical representation. Honeywell has developed detailed views of
performance metrics and higher level views for stakeholders who require less
technical detail.
Power of Analytics
Modern building management systems, such as Honeywell Enterprise
Buildings Integrator, collect an enormous amount of data from buildings each
minute. Building Analytics is
