ABSTRACT
Adaptability is a key component of sustainable design. Flexible planning practices are one way to rise to the challenges presented by the ever-changing technological, social and economic realities of today’s urban environments. An adaptable approach to city planning based on long-term trajectories may also reduce energy and material consumption. This chapter relates the heritage of neighborhoods to their sustainability, where social, economic and environmental issues are all present. The evolution of heritage conservation is also explored; and guidelines for the successful preservation of buildings and urban spaces, as well as the integration of new structures with old ones, are offered. The chapter concludes with a discussion of the Cité-Jardin Fonteneau project, which illustrates the insertion of a new neighborhood into the heart of an older community.
