Janis Birkeland presents the innovative new paradigm of 'Positive Development' in which the built environment provides greater life quality, health, amenity and safety for all without sacrificing resources or money. With a different form of design, development itself can become a 'sustainability solution'. A cornerstone of this new paradigm is the eco-retrofitting of the vast urban fabric we already inhabit. The author presents a revolutionary new tool called SmartMode to achieve this end. This book challenges everyone working in or studying the areas of sustainable development, planning, architecture or the built environment to rethink their current ideas and practices.
