A Study on the Characteristics of Internal and External Space by the Inflow of Light at Ewha Womans University Campus Center (ECC)

이화여대 캠퍼스센터의 빛의 유입에 의한 내·외부 공간의 특성에 관한 연구

The existence of light that implements the space and shape of a building and has a great influence on building materials, textures, and shapes creates various spaces along with the wishes of constant users in the building space. The inflow of light into the inner and outer spaces of the building is influenced by the characteristics of the material that passes light, forming a transparent, translucent, and opaque space. Light introduced through various types of materials creates a unique space effect according to the shape of the material. This study analyzed the architectural spatial characteristics and expression methods of Ewha Womans University Campus Center (ECC) designed by Dominique Perrault in connection with light from the perspective of space, materials, and time implemented in buildings. The Campus Center (ECC), called Campus Valley (25m wide and 250m long), built at Ewha Womans University with a history of 120 years, considered the context of the surrounding environment by organizing and natural movements from the main gate to the university building. The biggest feature of this architectural space is the void space created between the buildings. This empty space, which accepts external natural light, serves as the center of the building space and activates the inner space of the basement floor, making the most of the advantages of the empty space. The characteristics of the ECC campus architectural space linked to light are: Dominique Perrault thinks the site and architecture as one organic combination, and integrates and expands the interior and exterior spaces through the empty space through which light enters and blurs the boundaries. It forms the characteristics of the intermediate space. Unlike ordinary materials expressed uniformly, material changes such as metal panels and glass due to light give the space a texture to form various spatial senses. the change of materials and shadows according to the time of light blurs the boundaries between internal and external spaces, forms an integrated harmony between the structure and the finishing materials, adapts to the surrounding environment, and realizes the continuity of time and space. As such, the architectural space of the Ewha Women's Campus (ECC) Center consists of various spaces by introducing light around the long empty outer path from south to north, changing the sense of space due to overlapping transparent and translucent materials, and changing shadows according to the movement of light.
