This book offers the basics of embodied and operational carbon while discussing the inclusion of carbon emission in the GBRS at global and national level. This book also critically explores the important topic of embodied and operational carbon of buildings with insights on the strategies to measure and reduce embodied carbon in buildings through a case study and application approach. This approach assesses the impact of embodied carbon on the choice of structural systems, alternate building materials, alternate building technologies and air conditioning system. The impact of these alternate measures in reducing embodied and operational carbon is analyzed by demonstrating its use on a base case building, which is similar to an existing office building in India. The quantified data enables architects and designers to make early design decisions for a more environmentally sensitive approache to sustainable building designs. This book is a valuable resource for students, researchers, and practicing architects in understanding evidence based repercussions of  structural systems, use of materials, technology and air conditioning systems to design green and sustainable buildings.
