Wind turbine boosts green effort

The University of Essex has installed a wind turbine on a building as part of its energy efficiency campaign.

The turbine has been placed on the new School of Health and Human Sciences Building at the Colchester Campus.

The 9m (29ft) installation is expected to generate enough energy to power half the building.

During the turbine's anticipated 25-year life it will save more than 87 tonnes of carbon dioxide, bosses at the university said.

The QR5 design turbine was chosen for its visual impact since the campus is set in 200 acres of parkland.

Chris Woodman, project officer in the university's estate management section, said: "This wind turbine is specifically designed for an urban environment.

"Its triple-helix shape minimises noise and vibration to near silence and improves efficiency by creating an even driving force from the wind, more appropriate for near and around buildings."
