Abstract

Various approaches have been so far presented to achieve urban balance and sustainability, one of which is the ecological city. As the topics of sustainable development and its approaches have been brought up at the global level, especially in the environmental field, new horizons have been opened for managers and urban planners. The approach of the ecological city is a comprehensive and integrated approach that presents all the goals and dimensions of urban development with a focus on environmental sustainability, economic development, and social justice. This study aimed to model the sustainable consumption of materials and energy in ecological cities. Regarding the purpose, this study is applied in nature and descriptive-analytical in method. Document analysis was used to collect data. The results showed that there was a special emphasis on the development of ecological cities in the world. In the proposed model of the consumption of materials and energy of the ecological city, the emphasis was put on the use of clean energy instead of fossil fuels, the reuse of municipal sewage effluent and waste recycling to reduce the ecological footprint, the use of organic waste as compost fertilizer and rainwater for agriculture, and use of solar energy. Further, using renewable energy sources and consuming energy efficiently were the two main ways to achieve energy sustainability, reduce fossil fuel consumption, and hence, increase the supply of clean energy and green management.
