ABSTRACT

In recent years there has been a growing concern about climate change and Korea will be under the compulsory reduction duty of greenhouse gas after 2013. Accordingly, more efforts to reduce energy consumption are required than ever before. In particular, it is necessary to implement energy saving urban spatial structure strategies. The purpose of this study is to develop a model which can simulate dynamic changes of energy consumption according to changes of the urban spatial structure. This study attempts to construct the conceptual model which shows the complex interaction among four sectors such as population‧economics, land use, transportation and energy consumption sector. To develop the energy consumption model, system dynamics approach was used. The model was applied to Seoul city to testify the operational validity and to compare the energy saving effects according to 3 different scenarios. The result of computer simulation shows that total energy consumption changes dynamically until 2020 according to the changes in land use and traffic volume which are caused by changes from the population and employment. Simulation result of three scenarios shows that high density development in the commercial zone and mixed use development in the residential zone can reduce energy consumption. In addition, the current regulations on greenbelt should be maintained to maximize energy saving effects of high density and mixed use development.
