Abstract
The purpose of this study is to suggest ways to design for the environmental Interface of Long Life Housing. Research, improving the performance of the interface, is underway at the research organization of Long Life Housing. Infill system should accommodate the various changes in the space. So dismantlement, replacement, and repair of the act are essential. In this process, A lot of substance, which can damage or spoil the environment, may be produced. However, the eco-friendly aspects of the interface design of infill system is not made in the approach or evaluation. Therefore, this paper is to analyze the problem of Interface of Long Life Housing in terms of eco-friendly, and it try to find a design method, complemented in the next research.
