Globally, local authorities of existing cities must face many challenges: develop the city, generate jobs, ensure their attractiveness over time, structure a responsible and sustainable growth. It is a matter of not only reducing the energy bill of the local and regional authorities, respecting regulations to come but as well provide the citizens with a clean and healthy environment. The cities taking part of a virtuous effort on energy consumption reduction and climate change mitigation can only be done by integrating the impact of buildings or transports on the life quality in the communities. This report consider the technical aspect of their challenge through three components: the urban infrastructures (roads, celebrations lightings and so on), the public buildings (electricity, HVAC, cold, libraries, auditoriums, commercial hall, etc.) and the transports (access, parking lot and public transport projects, self-service bicycles, self-service electrical cars and so on). Many technical solutions are proposed along three different axis : reduction of energy demand, increase of the installation performance and improvement of people’s consumption behavior. Then all these solutions are chartered in terms of economical profitability (from quick wins to long term investments) versus energy savings (from 10% to 40 % or more). It is therefore possible to see where to study further through pre-diagnosis or more detailed studies in order to define the best options. This report demonstrate that technical solutions are already available, even very profitable ones.
