Given the importance of sustainability as one of the critical considerations in the built environment, mainstreaming sustainability into business and managerial activities is crucial to successful implementation of the sustainability agenda. This ebook identifies the variety of business drivers that should justify and motivate through-life sustainability of built assets, as well as the wide range of managerial implications in achieving such sustainability - at strategic and/or operational levels. Among the many facets of sustainability, the papers included in this ebook cover the subthemes of 'green buildings and sustainable infrastructure', 'procurement, processes, and performance', and 'sustainable construction'.
