Urban sprawl has often grown without regulations, resulting highly energy intensive. In order to reverse this trend, the paper focuses on the research for solutions aimed at energy self-sufficiency, exploiting the morphological peculiarities and environmental potentials. In this way, the recent examples of ecological and self-sufficient villages in Europe were analysed in order to extrapolate the strategies applicable to the existing urban sprawl. The paper develops guidelines for the construction of low impact building systems, regulating the metabolic cycles of habitat functioning (water, energy and waste). The proposed guidelines act as supporting elements for the sustainable design of the urban sprawl. The requirements of buildings to improve energy performance are identified, developing different levels of intervention. These guidelines aim to spread the eco-efficient culture especially in the residents.
