Zerofootprint, along with its partner the John H. Daniels Faculty of Architecture, Landscape, and Design, University of Toronto, welcomes nominations for the 2011 Zerofootprint Re-Skinning Awards. This annual competition celebrates the year's most successful, holistic building retrofitting projects from around the world. The Zerofootprint Re-Skinning Awards invites the best minds in architecture, design, building, and engineering to submit green building projects that demonstrate the innovative use of energy retrofitting technologies. Retrofitting and re-skinning involve the use of design solutions to dramatically reduce the environmental footprint of older, energy-inefficient buildings. This competition seeks to recognize the year's most progressive retrofitting projects that are making our cities more sustainable.
