Housing LCA and Environmental Load Data Base

Abstract

This paper introduces a housing LCA and Environmental Load Database for building LCA. The Architectural Institute of Japan（AIJ）has developed the housing LCA as the open source software. The database is then derived mainly from the Japan Input/Output Table, which is not only for building but applicable to all the LCAs. Additionally the practical LCA which aims to contribute effective reductions in emissions from housing is discussed. Further the expansion of a housing LCA towards a comprehensive Social-LCA and the further efficiency by Hot Spots Analysis are also discussed.
