Breathing Buildings, which specialises in reducing energy used in heating and ventilating, has been named in the 2012 Global Cleantech 100 list.
Produced by Cleantech group, the Global Cleantech 100 highlights the promise of private clean technology companies from all around the world, focusing on those companies which the players in the market feel are currently the most likely to make a significant market impact over the next five to ten years.

Shaun Fitzgerald, managing director of Breathing Buildings, said, 'We are committed to green technology and are proud to have been included in the Cleantech 100 list, especially knowing there were over 8,000 other nominations from 85 countries.'

The list is derived from Cleantech Group's own data and research combined with the weighted qualitative judgments of hundreds of nominations and the viewpoints of a global panel of 75 cleantech experts. To qualify for the list, companies must be independent, for-profit, cleantech companies that are not listed on any major stock exchange.

These companies were weighted and scored to create a shortlist of 236 companies presented to the expert panel for final input. The end result was 100 companies from 13 countries.

The 75-member expert panel is drawn principally from leading financial investors in Asia, Europe and North America, and from representatives of multi-national corporations. The composition of the expert panel is created to be broadly representative of the global cleantech community, and includes pioneers, leaders, veterans, and new entrants in cleantech.
