Sharon AI Plans Deployment of 8,200 NVIDIA Blackwell Ultra GPUs at GreenSquare’s Repurposed SYD1 Data Center Campus in Australia

NASDAQ-listed NVIDIA Cloud Partner Sharon AI will install approximately 8,200 NVIDIA Blackwell Ultra GPUs at SYD1, the newly operational data centre campus developed by GreenSquare in Norwest Business Park, Western Sydney.

GreenSquare characterises the deployment as a significant rollout of NVIDIA HGX B300 infrastructure in Australia, and it anchors the facility's entry into service.

A 1995 data centre given a second life

The site now hosting this compute capacity was not built from scratch. GreenSquare took a data centre originally opened in 1995 and adaptively reused it, keeping the existing slab and much of the structure rather than demolishing and rebuilding. Data halls were moved to the ground floor, which allowed the building to house the latest-generation, high-density compute without extra structural reinforcement.

The company reports that this lifted IT capacity within the original footprint by 275% while cutting structural carbon substantially.

Joshua Martens, GreenSquare's Chief Technology Officer, said the company saw an opportunity to give a 30-year-old data centre a completely new purpose. "By rethinking the building's configuration, introducing prefabricated systems design, and using the latest technology to reduce carbon, we've created a facility that can support some of today's most demanding compute requirements while using resources far more efficiently," he said.

Carbon savings quantified by TTW

An independent assessment by engineering consultants TTW found the adaptive reuse preserved 92% of the building's existing structural carbon.

Combined with low-carbon concrete, reusing the structure delivered 76% lower structural upfront carbon per square metre and 93% lower carbon per kilowatt of IT capacity than a new-build facility would have, according to the assessment.

Design targets sit below NSW guideline benchmarks

Efficiency was a design priority alongside carbon. SYD1 is projected to run at a power usage effectiveness of 1.20 and a potable water usage effectiveness below 0.1 litres per kilowatt-hour, both better than the NSW Government guideline benchmarks of 1.25 for PUE and 1.0 for WUE.

The building's original water-intensive cooling towers were replaced with a closed-loop system that avoids evaporative cooling for roughly 96% of the year. Rainwater harvesting is expected to cover about 10% of annual cooling water needs, easing the draw on potable supplies.

Eight-month delivery backed by 400 workers and zero lost-time injuries

Main construction began in February 2026, and the first stage was delivered in eight months. Around 400 people were on site at peak, with teams working around the clock during critical phases. The project logged more than 350,000 hours without a lost-time injury.

GreenSquare built and delivered the facility with Erilyan, while Fredon handled the electrical infrastructure and commissioning, converting the existing building into an operational campus equipped with liquid-to-chip cooling for high-density AI workloads.

Stage 2 endorsement and portfolio growth

SYD1 Stage 1 is the first installment of a larger campus. The NSW Government's Investment Delivery Authority has endorsed support for a proposed 80 MW second stage.

With Stage 1 delivered, GreenSquare is expanding its Australian data centre portfolio under programs managed by Partners Group, with a stated focus on responsible development, resource efficiency, and long-term performance.
