The world is beginning to feel the crunch of depleting conventional energy sources and these desperate times call for exploring newer vistas in terms of alternative sources of energy. The construction sector is expected to require a major overhaul involving strategic advancements in the utilization of green energy given the rapid urban growth. A number of policy initiatives to mainstream energy efficiency are in place in most countries that are expected to accelerate energy efficiency and sustainability in buildings. Streamlining the green building movement requires coordinated monitoring and intelligent control of a building's vital functions. This can be achieved through building management systems (BMS) involving the integration of structures, systems, services, and management. Green building movements should examine the potential of power generation from urban, municipal, and industrial wastes. Equitable distribution of water resources should be carefully planned monsoon-dominated countries should adopt efficient rain-water harvesting measures to provide clean water to thirsty nations. These overarching concepts are well woven into themed chapters in Green Structures: Energy Efficient Buildings. Easily comprehensible to undergraduates in civil, structural, and environmental engineering; graduate students and researchers; town planners; and architects worldwide, the content of this book not only comes from courses on energy efficient buildings taught by the authors, but also from new and original research. This definitive resource has an enduring appeal for all those concerned with green structures.
