Subzero Engineering: Sustainable solutions for data centres

Consultancy and customised containment - which complement the data centres they work with - is the global calling card of Subzero Engineering

Subzero Engineering recognises data centres are dynamic environments, so they have created customised containment solutions which make energy-efficient savings for their customers.

Subzero Engineering is the industry leader in bespoke containment solutions using computational fluid dynamics (CFD) to show measurable results for their customers which includes the following savings; $300 million in energy costs, 1.5 billion gallons of water, and three million tonnes in the reduction of carbon dioxide since 2015.

“We believe that a data-driven approach is essential to drive data centre performance and efficiency,” commented Andy Connor, Director EMEA Channel, who points out they offer CFD checks for free. 

“We help our customers do this with our customised, streamline, and energy efficient containment solutions which result in a lower total cost of ownership and reduced carbon emissions.”

Subzero Engineering has manufacturing facilities in Salt Lake City, US, where they were founded in 2005 (starting out as a data centre airflow consulting company), and in Dublin, Ireland.

“We have a large team of leading industry experts that help us operate globally, and at speed, and we work with customers ranging from the hyperscalers and colocation communities through to well-known brands and sports, retail, HPC, and AI,” said Connor.

Partnership with atNorth

Subzero Engineering has been working with atNorth, a high performance sustainable data centre in Iceland, for the past three years.

“When atNorth began the process of building their data centre halls they got in touch with us to provide the hot and cold aisle containment systems. Their facility is unique in its structure, so we moved from simply providing containment solutions to working with them consultatively to create a standardised ultra-efficient and performance focused system and something that could be repeated across multiple sites as their business grew.”

Climate neutral data centre pact

One of the drivers which is currently influencing data centre design is the fact hyperscalers and members of the colocation community have signed up to the climate neutral data centre pact. 

“New data centres are being designed for sustainable operations, but it needs to be more flexible to accommodate the needs of GPUs chip and processing power, so there's a real challenge to find that balance,” said Connor. “However, I think the real challenge in the market is the legacy facilities. These really need to be updated and modernised to become more efficient in order to reduce their OPEX, energy consumption, and CO2.”

Balance performance and efficiency

Connor says Subzero Engineering helps operators balance performance and efficiency. “We started life back in 2005 as a CFD consultancy when data centres were using raised floors and experiencing issues with leakages. Our software solution showed customers how they could analyse the infrastructure and improve efficiency.

“Fast forward 16 years and that approach has stayed with us. We're an engineering-led solutions provider who helps businesses reduce their carbon footprint and operating costs - but it all starts with the data we produce from our CFD reports,” he said.
