Abstract

(Background and Purpose) Recently, a residential complex community development that provides medium/high-density housing and living SOC using the blighted low-rise residential area in the downtown area is being developed. Architecturally, the high-density integration of complex programs is essential to simultaneously satisfying different requirement for environmental performance and each use. As the existing black box design method has a limit to its response, this design focuses on the design method using a multi objective optimization algorithm and considers the impact of the adjacent context including the own building within the site. We propose a design for a residential complex community space that reflects the optimal architectural composition that satisfies the different design conditions that conflict with each other. (Method) For design example, it is set as a residential complex community space including residential, commercial, and community facilities that respond to community problems for blighted area located on a slope site in the Jeongneung Redevelopment Area in Seoul. Based on the relationship between the adjacent context and the group of buildings on the site, the design is drawn based on the site plan and shape that simultaneously satisfy the environmental optimization based on insolation and the view and perception requirements for each use. To do this, it utilizes Octopus, a multi objective optimization add-on based on Rhino Grasshopper. The optimal solution that meets the complex requirements of the example is selected and applied to the final design through the review of performance and planning for multiple solution groups derived from Octopus. (Results) The derived design includes not only site plan and shape of the most importantly, but also urban and architectural aspects that respond to various requirements for the community. First, from an urban point of view, the social integration of the community was strengthened by providing functions required to respond to the physical and socio-economic problems of the community cut off from the surrounding. From the architectural point of view, through the calculation results derived from the optimization, a number of complex conditions including the environmental performance of complex including local facilities were satisfied. In addition, from a technical point of view, evidence-based design based on objectivity that goes beyond the limits of subjective arbitrariness inherent in the existing architectural design process was applied. (Conclusions) This design confirmed the applicability and potential use of an optimization genetic algorithm linked with a new digital tool in architectural design by deriving alternatives to the set examples. The effectiveness of multi objective optimization to overcome the limitations of traditional design was confirmed. Furthermore, it has meaning in expanding the versatility of practical grafting of advanced new technology and architectural design.
