초록

(Background and Purpose) Recently, a number of complex projects are underway to expand green spaces and living SOC by utilizing idle lands in the cities. The purpose of these projects is to secure environmental performance that is the most essential requirement for a community complex located in the city center. Therefore, this study focuses on the importance of the environmentally optimal relationship between the exterior spaces, where the influence of the adjacent context is reflected, and the buildings and proposes a community complex design as a counterplan by optimization. To this end, an exemplary site with specific conditions is selected and a multi-objective genetic algorithm that simultaneously computes multiple conditions linked with environmental data is applied to derive an optimal site plan and an architectural design. (Method) As an exemplary site, an idle land that remains as a physical, socio-economic boundary in the communities due to the demolition of old facilities, is selected, and an overall plan for a community complex is drafted based on the optimization process. Rhino, Grasshopper, parametric design tools, Ladybug, an add-on for environmental analysis, and Octopus, an add-on for multi-objective optimization, are used. First, the site plan and architectural form optimized to achieve the optimal environmental conditions for solar radiation within the site are derived. Then, the optimal configuration for the external shading system is derived. The location of the buildings is determined based on the influence of the adjacent context and the relationship between each building; the architectural form is determined based on the orientation of the building linked to the solar radiation and the exterior mass. the exterior shading system is determined based on the optimal shielding rate by the size and spacing of each pin depending on the horizontal and vertical shading systems. (Results) The design included not only the site plan, form and exterior design, but urban and architectural proposals that respond to problems of the communities. First, to resolve the problems which have been cut off by the site, the social integration of the communities were reinforced by providing facilities and functions that would meet the needs of the communities. From the architectural perspective, the environmental performance of the urban park including facilities was optimized by genetic algorithm optimization. From a technical perspective, a multi-objective optimization process that goes beyond the limitations of the existing single-objective optimization. (Conclusions) Multi-objective optimization that utilizes environmental data was introduced into the design process to propose the possibility of a new performance-oriented design method based on an environmental perspective. Furthermore, this study is of great significance in that it proposed a pioneering perspective for practical integration of new technology and architectural design.
