This book aims to further the debate on new sustainability thinking in the built environment, by bringing together a selection of short contributions from thought leaders in the UK and the rest of the world (USA, China, India, Australia, NZ, Indonesia) with an overarching narrative from Martin Brown. Although progress in sustainable solutions has been made over the past decade, the trend is still one of a woefully wasteful construction industry. This book aims to show that being ¿less bad¿ is no longer good enough. The book also spotlights digital sharing and collaboration through social media and BIM as new tools in the ¿sustainability toolbox¿ which provide unique and powerful opportunities to rapidly advance sustainability thinking, development and action.
