Introduction

This book presents knowledge on sustainability concepts, policies, and technologies adopted in both developed and developing countries. The book covers five themes: (a) advancing sustainability building rating systems, (b) promoting retrofitting buildings and warranting energy-efficient buildings, (c) realizing water efficiency within building structures, (d) application of the circular economy to manage waste, and (e) enhancing the health and well-being of building occupants.

Theme 1: Building Rating Systems

The first theme includes case study-based evidence and solutions to different rating systems used in different countries.

Theme 2 and 3: Energy and Water Efficiency

The second and third themes mainly focus on the achievement of sustainability under the key parameters of energy efficiency and water efficiency through the application of various techniques and technologies, such as green roofs, green walls, and grid-tied solar photovoltaic technology, with a special emphasis on retrofitting techniques, in different case study contexts.

Theme 4: Circular Economy

The fourth theme primarily addresses the need to clarify misconceptions surrounding the concept of the circular economy within the construction industry. It explores its broader applications in various contexts, aiming to uncover opportunities for knowledge expansion and transfer across different countries.

Theme 5: Occupant Well-being

The fifth and final theme of the book addresses various good practices and tools developed to enhance the health and well-being of building occupants, with a primary focus on how such things help achieve sustainable buildings.
