Superimposed Renewal of Industrial Heritage under the Guidance of Low Maintenance and Sustainability—Renewal of Refinery Site in Jinan Tianhong Community

The renewal of industrial heritage is a long process. With the development of society, a single form of renewal can no longer meet the needs of the public and environment in China. In the case that a large number of industrial heritage sites require secondary renewal, it becomes an urgent issue to consider how to achieve sustainability in the process of superimposed renewal, reduce the amount of future renewal changes, and at the same time realize economic and environmental friendliness, reduce maintenance costs, achieve cyclic spontaneous renewal, and ensure the feasibility, variability and growth of the reserved renewal. Jinan Tianhong Community Refinery Industrial Heritage Park was selected as the case study in this paper based on the theory of low maintenance to explore the strategy of superimposed renewal under the guidance of low maintenance and sustainability-oriented superimposed design in the social process; thus, the design of the secondary renewal of industrial heritage can create an eco-friendly space for activities from an ecological perspective, so as to achieve low-maintenance, low-intervention and sustainable industrial heritage renewal in the long-term.
