Abstract

The design of complex, high-performance facades involves balancing attention towards principles of material selection, thermal and moisture protection, structural integrity, and durability. When these demands are coupled with the desire to create aesthetically interesting and “beautiful” skins, design teams may find themselves tasked with reconciling conflicting formal and performative drivers in the creation of an exterior envelope. The formal vision of a complex façade skin, for example, may not be appropriate for the climatic and site-specific realities of a given project location; material properties, compatibility, and interface will also often pose issues of concern. Technical designers will typically negotiate these challenges within the detailing of a given system. However, through the research and interrogation of given systems earlier in the design process, disparities between design considerations and technical drivers can lead to unexpected and innovative solutions.

This paper will present design and fabrication processes employed in the development of a high-performance complex façade for Kolon Future Research Park, a research laboratory building in Seoul, South Korea. The main facade of the building has been designed with the intention to serve as visually-striking, exemplary construct demonstrating the client’s commitment to innovation, technology, and sustainability. To achieve this design, a second skin of composite construction was developed using parametric design workflows and building performance analysis. Fiber reinforced polymer (FRP) was selected as the final material for the external sunshades, given the material’s durability, structural characteristics, and potential for plasticity in form. A monocoque sunshade assembly that challenges conventional formal notions of solar shading was developed for the project. The resultant body of the continuous outer skin is reflected in the glazed wall behind, to create visual complexity and tension amplified by the sense of weightlessness that the minimal support structure affords.
