Fujitsu Data Centre, Australian First

Two halls of Fujitsu’s Noble Park data centre were the first in Australia that has been awarded an official NABERS rating, a complex six-month audit conducted by Bob Sharon, CIO of Blue IoT that was approved by the NSW Government.

The National Australian Built Environment Rating System (NABERS) is a national rating system that measures the energy efficiency, water usage, waste management and indoor air quality within the built environment. The rating system was launched in February 2013 and assesses the building infrastructure and IT equipment of data centres.
Bob Sharon conducted the world’s first NABERS audit for a Data Centre which was for Fujitsu in 2013 making him the only NABERS accredited assessor for DCs and IT Workload in Australia at that time. Bob was fully equipped to deal with the unique challenges presented by the plant that supplied power and cooling to 2,000+ square metres of server rooms at Building One of Noble Park (Halls 1 and 2).

The rating was completed by calculating twelve months of energy consumption based on third party verifiable data. Bob Sharon said, “the first official NABERS audit resulted in a lot of lessons for all parties.”


As part of the Infrastructure audit process, extensive metering and energy management system was used to provide a detailed record of energy consumption.

Some of the key components of the assessment include:
• Gather single line diagrams.
• Conduct site inspection to follow the single line diagrams
– looking for the right PDU, meters etc.
• Investigate racks, IT equipment and in rack mechanical kit
during the site inspection.
• Facilitate meetings with the data centre managers, facilities
and the stakeholders.
• Certify selected and relevant meters for testing/validation
in terms of accuracy.
• Read all relevant meters and compare them to the readings
of their Scada system to ensure that the remote meter
reading functions were accurate.
• Source right data and logs from Fujitsu that was held within
their Scada system.
• Validate power information and provide details for the
certification to achieve the NABERS rating

This assessment uncovered accurate findings that enabled Fujitsu to achieve a 4 Star NABERS rating and strengthen its sustainability strategy. The NABERS rating has been invaluable in helping Fujitsu to validate its efforts to reduce data centre power consumption and further help to pre-empt the future demands of federal government clients.

“This was the very first NABERS Data Centre rating in history and there were many queries and about 300 hours of my time to get to a final result. Another problem here was that within the IT load one of the CTs on the main PDU was faulty and didn’t record one of the three phases. This was in fact the difference between going 3.5-star or 4-star, so the loss of that power within the IT load was a huge difference. NABERS rules do not allow extrapolation as we looked at various options. In the end, we found another system within Fujitsu that recorded and measured the power apart from the faulty CT. This was accepted and made the difference, allowing for a 4-star rating.” – said Bob Sharon

Client Testimonial

Lee Stewart, Head of Sustainability at Fujitsu Australia, said

“The company opted to be the first to achieve a rating to

validate its efforts to reduce data centre power

consumption.” Further adding to his comment, Lee Stewart

said “Fujitsu used Bob Sharon because he was already

certified and had extensive Data Centre experience.”

Business Improvement Director, Duncan Else and the team at Colussus in late 2020 have partnered with Blue IoT to deliver impressive cost-reduction solutions for all building types.

Colussus prides itself to build green energy and make available to every business lowering greenhouse gases and energy bills.

“Having worked in Telecommunications, Solar and Insulation my entire career, I’ve created Colussus to help businesses reduce their outgoings with Blue IoT’s Encompass Blue solution, provide green sustainable energy and give them public recognition for their contribution.” said Duncan Else.
