Breathing Buildings, the natural ventilation specialist based in Cambridge, has been shortlisted for the 2013 Ashden Awards.
Now in their 13th year, the awards champion sustainable energy trailblazers that are helping to reduce the UK's CO2 emissions, while improving lives and boosting local economies.

Breathing Buildings 'delivers low energy buildings with superb indoor climates, thanks to its patented e-stack, low energy natural ventilation technology'.

Dr Shaun Fitzgerald, managing director of Breathing Buildings, said: 'We are delighted to be shortlisted for the Ashden Awards. Breathing Buildings continually strives to reduce energy bills by re-thinking natural ventilation in order to avoid the cold draughts normally associated with this type of system.'

Finalists will be announced in May 2013 and the awards will be presented at a prestigious ceremony to be held in London on 20 June 2013.
