Exploration on development mode of material and energy circulating metabolism on university campus:a case study of Chang’an campus of Northwest Polytechnical University

Every university campus usually bears the living consumption of materials and energy for thousands of people, and the linear metabolism aggravates the waste of materials and energy,and worsens the environmental pressure. However,the university campus can provide the additional site for the cycle facilities of the material and energy because of its abundant occupied land and low building density.Hence,the Chang’an campus of northwest polytechnic university will be studied as a typical case,and the development mode of material and energy circulating metabolism will be explored on the basis of the perspective of architecture and the focus point of material and energy circulating metabolism.The findings in this study will provide a new insight into developing the ecological mode of colleges and universities, thus propose a new solution to the ecological crisis
