Abstract

Energy shortage and global climate change have created a dilemma in Japan, especially after the great earthquake of 2011 in eastern Japan. District Heating System (DHS) using waste heat is highlighted as an attractive solution. However, because of low heat demand in urban areas and the geographic separation of industries, popularizing this solution is considerably difficult in Japan. Previous studies have focused on technical improvements on existing district heating networks, but these studies lack sufficient discussion on an early-stage integrated land-use planning. Supported by technological assessment and emerging concepts of Industrial-Urban Symbiosis (I-US), this study combines the system development of DHS and land use scenarios into a symbiotic design based on inventory survey and geographic database, and conducts a cost-benefit analysis to scientifically and quantitatively evaluate the effects brought from land-use policies. Results from a case study of Shinchi Town in the Fukushima Prefecture indicate DHS using waste heat can realize significant benefits of energy saving and CO2 reduction, provided positive guidance on land use planning is implemented. Moreover, the model framework of this study also supports a quantitative assessment on policy implementation to help in decision making on urban sustainable energy planning.
