EFFICIENCY

Efficiency is a concept related to the urban metabolism, i.e. the flows of materials, water and energy. These elements make up the backbone of urban systems, whose organization must be maintained and whose contamination must be avoided. The management of natural resources within an urban system must be efficient with minimum disturbance to the ecosystems.

In the field of energy, ecosystemic urbanism argues that for new neighbourhoods to overcome their status as mere consumers of energy, they must become generators of renewable energy and be working towards self-sufficiency. The generation of renewable energy is combined with conservation and efficiency measures.

In order for the city to run, it is essential to integrate both water and waste management.

In integrated waste-water management systems, it is important to consider the local scale and the urban area’s proximity to the water basin. In order to maximize self-sufficiency, it is essential to combine measures of water self-sufficiency with conservation and efficiency measures. Moreover, it is essential to link urban development to the local water cycle (the capture of rainwater and the reuse of marginal waters).


In terms of local resources, it is important to achieve maximum self-sufficiency. To do so, we must account for the natural resources available in each area, and strive to reuse wastewater from residual streams. The waste management model was designed using sustainability criteria, and will achieve maximum local control of water management. It proposes a closed system with regards to the materials cycle and, where feasible, it incorporates self-composting and reusing of resources.


Included in this area is food production, with the objective to have the majority of the food consumed in the urban area to be produced in a sustainable, ethical way.
