Bristol University has officially opened its green building on the campus today. The building was unveiled by renowned broadcaster and naturalist Sir David Attenborough.

The Life Science building has got an 'Excellent' BREEAM rating, and has just welcomed its first students. The department wants to be at the forefront of science research. Sir David Attenborough saw first-hand the world-class facilities for science research and teaching within the University of Bristol's Life Science building. The Life Sciences building will help researchers to study plants, animal behavior and evolution.

It is the university's largest construction project to-date and it will be the central point for global scale research in areas as food security and environmental conservation.

"Nothing could be more important in the area of scholarship than this. Understanding the natural sciences and the processes that brought us here - these things bring joy and resonance and happiness to our lives", said Sir Attenborough.

The work to build the 13,500 square meter iconic building started in July 2011 and it was completed during the summer. To complete the project, a total of 2,000 people have worked with 28 architects from 10 countries.

Patrick Finch, Bursar at the University of Bristol, said that this building and its public area have represented the most motivated project taken on by the University's Estates Office to-date.

The Life Sciences building consists of one of the largest teaching labs in the country, capable of teaching 200 students at once. There are multiple screens to make sure that all students can see close-up what the lecturer is doing and moveable walls can alter the size of the teaching space.

The space nearby the building has also been designed again with 21 trees and 3,215m2 of shrubs and grasses.
