Redefining the future of indoor climate control

At BGF, our Early Stage team backs bold ideas and exceptional teams tackling meaningful global challenges — and few challenges are as urgent, pervasive, and overlooked as the energy usage of buildings. That’s why we‘re excited to be backing Artus Air.

A spinout from Arup Ventures’ incubation hub, Artus Air is reimagining HVAC (heating, ventilation and air conditioning), with a radically more efficient approach to indoor climate control.

The historic, hidden cost of comfort

This is the problem Artus Air is tackling head-on.

Traditional HVAC systems in commercial buildings are characterised by high energy consumption, significant space requirements, and substantial installation and maintenance costs.

With extensive ducting and bulky components, fitting them into a building can be a drawn-out process that eats into ceiling space and design flexibility. Once up and running, they often overwork to compensate for system losses, driving up energy use and electricity bills. And when something goes wrong, repairs are anything but simple.

And it’s not just about cost and complexity — traditional HVAC systems are also a major climate offender. Air conditioning alone consumes around 7% of global electricity and accounts for 3% of greenhouse gas emissions.

As the push towards net zero accelerates, the pressure is on for building owners to clean up their act and comply with regulations.

A smarter, smaller, more sustainable solution

Retrofitting existing spaces with smarter, more energy-efficient tech is quickly becoming one of the most impactful ways to reduce costs, cut carbon, and meet energy saving standards.

Artus Air is playing a key role in retrofitting more carbon-efficient HVAC systems and setting new standards within the industry. Its compact, low-energy air conditioning unit was developed by a team of engineers and designers with decades of experience in building services.

Compared to a standard ducted fan coil unit, Artus Air’s technology delivers:

  • 87% reduction in operational energy usage
  • 13% overall cost saving
  • 3x faster installation
  • 66% whole life carbon saving
  • Market-leading comfort from patented air distribution technology

This isn’t just an incremental improvement — it’s a validated step-change in building technology, addressing not just energy use, but also space efficiency, flexibility, maintenance, and user experience.

“Artus Air is pioneering and delivering energy-efficient climate control technology that can make a real difference at a time when building emissions are under close scrutiny.”

Why we invested in Artus

We initially invested in Artus Air in 2023, to accelerate the company into its next chapter: scaling production, building out the commercial team, and expanding internationally.

Beyond its breakthrough HVAC solution, what impressed us further was the quality of the company’s early commercial traction and its leadership team.

Strong commercial traction

When we met with Artus, hundreds of its units had already been deployed across flagship real estate developments. This has now scaled to thousands of units, and the company is well-engaged with key decision makers across the value chain, including leading developers and architects.

Visionary leadership

The business is led by an exceptional founding team, with deep domain knowledge and a clear vision. CEO Rebecca Stewart and her team blend engineering excellence, product focus, and commercial acumen. And they’re complemented by Non-Executive Chair Catriona Schmolke CBE FREng, who brings 15 years’ experience in the industry, as a business leader and engineer at Jacobs.

“The investment has enabled us to effectively resource our operations, in time to serve our significant swell in customer demand, including internationally. What’s more, their support of the marketing megaphone is unique and very welcome. It’s given us a great leg-up in communicating a person-to-person brand and buying journey that our customers identify with and enjoy being a part of.”
