Dunnett and Kingsbury look at examples of ornamental projects while stressing the concept's solid link to the environment. Examinations of recent research underline the wide-ranging benefits of greening buildings, from recreational aspects to increased energy efficiency. Among the most positive changes to emerge are improvements in the air we breathe and the support of biodiversity. Given the lively current interest in how to extend living ecosystems that reach beyond the ground plane to the upper stories of our homes and office buildings, this resource offers important technical advice, along with horticultural recommendations pertinent to flat or sloped roofs and the greening of vertical surfaces. Undoubtedly, other manuals will appear as an interest in living roofs increases.

This book introduces a revolutionary new concept to gardeners. Planting on roofs and walls began in Europe, but it is now becoming popular all over the world. Green roofs and walls reduce pollution and run-off, and also help insulate and reduce the maintenance needs of buildings. Planting Green Roofs and Living Walls discusses the practical techniques required to make planting on roofs and walls a reality. It describes how roofs may be modified to bear the weight of vegetation, considers the different options for drainage layers and growing media, and lists the plants suitable for different climates and environments. This informative book will encourage gardeners everywhere to consider the enormous benefits to be gained from planting on their roofs and walls.

Plants used to create green walls and roofs can reduce the urban "heat island" effect and create usable green open spaces. This book's discussions on Intensive Green Roof, Extensive Green Roof, Eco-roof, Brown Roof, etc is interesting. This book is a serious attempt on a difficult subject. The color photos inside the book are helpful also.
