n Principal Environmental Activities in Fiscal 2013
ICT has become ubiquitous, always on, always available, and on
any form factor. University students expect 100% uptime, 100%
availability, and delivery of learning materials to the platform of
their choice. For University Campus Suffolk (UCS) that meant trans-
forming its legacy datacentre.
The objective that UCS set itself was to reduce power consump-
tion by 80% and used floor space by 70%, as well as delivering
increased uptime and performance. To achieve this ambitious
goal, UCS worked in partnership with Fujitsu to implement a
technology replacement program.
The program commenced with the installation of a new storage
area network (SAN), consolidating all storage into two FUJITSU
Storage ETERNUS DX80 SANs. The second stage of the program
was an ambitious virtualization project, which consolidated
nearly 100 physical servers into five FUJITSU Server PRIMERGY
RX300 units.
The success of the datacentre transformation project has led
UCS to increasingly adopt Fujitsu technology, including the recent
In December 2013, Fujitsu supplied life insurance sales personnel
with a tablet solution that forms a core part of their policy man-
agement system.
Previously, insurance sales personnel used large amounts of
paperwork to conduct their business transactions, which needed to
be done at their offices. But with this solution, thanks to tighter
security functions, it is now possible to go through the entire
administrative process at the client’s premises, courtesy of being
able to use the tablets to provide everything from product expla-
nations through to policy sign-up. The process is now paperless
and this has eliminated extra travel from customers’ premises back
to sales personnel workplaces.
Fujitsu Component Limited is striving to reduce energy use by
changing the humidifying methods used in clean rooms and making
effective use of exhaust heat from compressors in its R&D centers.
Conventionally, humidity in touch panel manufacturing plant
clean rooms came from steam in boilers within air conditioners,
but due to insufficient humidifying capability and other issues, the
method was changed to a pure water spray humidifying method.
This improved humidity management and control, as well as reduc-
ing the amount of fuel needed to run the boiler. Furthermore, the
cooler inside the clean room had previously been used throughout
the year, but switching to a pure water spray absorbed heat
through evaporation, lowering the room temperature, and reduc-
ing the cooler burden (cutting power consumption by the cooler).
Since compressors emit exhaust heat, coolers were used to
prevent rising room temperatures and to control reduced efficiency
in devices. Water purifiers, on the other hand, heated the raw water

using the boiler’s steam. Using heat exchangers to heat the raw
water by the heat emitted from the compressors led to simultaneous
reductions in consumption of power for the coolers and boiler fuel.
The result was a reduction of approximately 650 tons of CO2
emissions (–20% decrease compared to the previous fiscal year)
and over ¥20 million in costs over one year.
Assessing the environmental contribution effect on the cus-
tomer showed there had been a greenhouse gas reduction of
43.1% (Fujitsu calculations). Going paperless had saved tens of
millions of sheets of paper,
but reduction effects could
also be seen in reduced
movement of people (busi-
ness trips and travel
expenses) and reduced
office space (with energy
saved by using less light-
ing and air conditioning).
