How do you heat a public swimming pool using a Deep Green data centre?

On the 29th of February, over 100 people gathered to hear our CEO, Mark Bjornsgaard describe Deep Green’s ambitions, and then a fantastic panel discussing the responsibilities of business in the climate emergency.

Couldn’t be there? Watch the recap below…

“I loved this event and I am 100% committed to supporting Deep Greens ambition and endevour.”

Together we explored

  • Why saving the public swimming pools of the UK is critical 
for healthy communities.
  • The vision and purpose of Deep Green, and how and why it works for clients.
  • The importance, socio-economic and environmental benefits of circularity in infrastructure and technology.
  • How business can generate measurable social good today.

The panel perspective.

Portrait of Georgia

“I think we’ve just naturally divorced ourselves in industry from that we create so much waste, and it’s just madness that we’re venting heat to the atmosphere, when actually that is something that we desperately need in our homes, in our workplaces, (and in our public pools).”

Georgia Elliott-Smith,
Managing Director, Element 4

“We’ve always been on a mission of sustainability as well. And ever since meeting Mark (Bjornsgaard), from the first meeting, we were absolutely sold on the idea of working in partnership and collaboration.”

“It’s been really exciting to be part of the journey to render films using immersion tanks in Exmouth, with the waste heat being reused to heat the local swimming pool. Everyone I speak to in the film and TV industry is interested in sustainability, and they all want to know how they can get involved in projects that support initiatives like heating pools through data centre waste heat.”

“How do you save a public swimming pool with a datacentre? The movement can’t start without you in the audience.”

“The discussion is framed around the question of how we can say that swimming pools are good, while also acknowledging there is a huge issue facing swimming facilities. Deep Green’s existing work in Exmouth shows potential as a promising solution to this problem. Expanding their model further is something I would be very keen to support going forward.”

Head of Public Affairs, Swim England

Six key learnings.

Immersion Cooling

Using oil immersion to cool datacentre servers efficiently without needing to cool entire rooms.

Heat Sinks

Reusing waste heat from datacentres by sinking it into nearby buildings/infrastructure like swimming pools.


The mutually beneficial relationship between datacentres that need to expand and buildings/facilities that need heat like pools.

Sustainability Reporting

Growing regulations requiring companies to report on and be accountable for their full environmental and social impacts.

Social ROI

Considering non-financial returns like community benefits when making business decisions, not just profits.

Heat Use

Using waste heat from computing processes like datacentres for applications like building heating or pool heating through technologies like immersion cooling and heat exchangers.

It starts where you are – how to use a data centre to heat a swimming pool.
