This book addresses a topic of great relevance today, considering that in developed countries, most of the time is spent indoors; therefore, indoor residential environments have a direct influence on human health. Furthermore, in developing countries, significant levels of indoor pollution make housing unsafe, which has an impact on the health of its inhabitants; thus, housing is a key factor in the health of people around the world. In this book we look at a range of innovative research and evidence-based policy ideas that demonstrate the importance of housing research and policy for health and well-being.
