This book focuses on the relationship between buildings and our health and wellbeing, and by extension our quality of life. Expanding on the 50th anniversary Special Issue of Building Research & Information (BRI), which was dedicated to health and wellbeing, articles have been extended and updated to complement contributions from new authors. Building Health and Wellbeing covers design for ageing, energy poverty and health, productivity and thermal comfort in offices, housing space and occupancy standards, and much more. The aim is to explore the inter-relationship between people and our buildings. Chapters are supported with new case studies to illustrate global approaches to a common challenge, while demonstrating local strategies to suit different climates. The content covers housing, offices, and healthcare facilities and the unique aspect of the book is the people perspective, providing outlooks from different age groups and users of buildings. It will act as an important reference for academics in the built environment and healthcare sectors.
