Abstract
The improvement of a building appearance, environmental and structural performance is required for an existing building as an asset quality upgrading in case of refurbishment to sift sustainable society. The authors developed an integrated facade system which improves those performances to install a buckling restrained brace and external louvers. In this paper, the authors examine unique integrated facade system which formed like a bounding trajectory appearance through design process and making detail mock up. Finally, the system is validated by not only design process but also industrial and installation approach.
