Fujitsu has become the first data center provider in NSW to achieve a NABERS energy for data centers rating for two of its Sydney data centers.

The vendor's Homebush Bay facility has been awarded a 3.5-star rating, with the Western Sydney data center garnering a 4-star rating.

Mike Foster, Fujitsu Australia and New Zealand CEO, says the rating provides customers with an independent validation of the company's application of best practices in energy efficiency of data centers.

“Our data center team is constantly working on ways to improve our facilities, processes and practices across our national data center footprint.

Fujitsu's Noble Park, Victoria data center claimed the accolade back in 2013, being the first data center in Australia certified under the NABERS data center scheme.

The national rating system measures energy efficiency, water usage, waste management and indoor water quality within the built environment, and has recently been extended to data centers.

Fujitsu says its Homebush Bay facility underwent an extensive refurbishment in 2008 and now includes a high density, hybrid cooling technology using recycled chilled water and spatial layout planning to minimise thermal currents.

The facility also features a closed look cooling system to reduce the amount of water required to maintain industry standards for temperature and humidity,  and a state-of-the-art building control management system, allowing monitoring of power consumption in real-time and adjustment of settings to maximise efficiency.

The Fujitsu Western Sydney data center, commissioned in November 2011, was purpose-built with energy efficiency as a prime consideration.

As well as the features of the Homebush facility, it includes diesel rotary uninterruptible power supply (DRUPS), indirect free cooling, a heat-reflective roof, storm-water harvesting and the extensive use of recycled materials
