Natural ventilation company secures funding

Natural ventilation company, Breathing Buildings, has secured an investment of £400,000 from the Low Carbon Innovation Fund (LCIF).

The investment is part of a total funding package worth around one million pounds.

The LCIF is managed by green merchant bank Turquoise International and the investment will support Breathing Buildings as it seeks to commercialise its low energy ventilation system. 

Breathing Buildings, a University of Cambridge spin-out company which was founded in 2006, has developed the e-stack natural ventilation system.

This energy-efficient solution, which has been designed primarily for use in new buildings, helps to reduce power bills, minimise the building’s carbon footprint and provide better air quality so occupants can work more efficiently.

The company has won several awards, including being honoured as a Top 100 Sustainable Solution at Rio+20, as well as winning the 2012 Berti Green Accelerator Award.  

The Breathing Buildings e-stack technology works by mixing incoming cold fresh air in winter with hot interior air to create a comfortable working environment, in which air quality remains high.

In the summer months, the system typically operates higher ventilation flow rates but can also be used in conjunction with thermally massive building types to exploit the benefits of passive night cooling.

The company is currently to the challenges of multi-temperature buildings, such as those with refrigeration plants or high heat-generating server stacks.   

Shaun Fitzgerald, managing director of Breathing Buildings, said: “The operation of buildings accounts for almost 50 per cent of the energy consumed in the developed world. This is why it is so important for us to ensure that new buildings are low energy.

The e-stack system can be installed in a broad variety of building designs, helping to reduce energy use and supporting cost control while retaining air quality. With schools, supermarkets and healthcare facilities all operating the Breathing Buildings e-stack system, we are looking forward to the next stage of our growth, using the LCIF funding to expand our sales and technology offering.”
