抄録

This article summarizes historical evolution of the idea of eco-design in building related industry. The idea has generated from the idea of environmental symbiosis as an alternative concept of modern buildings where the built environment is artificially and proactively controlled. Then, influenced by Bruntland report, the idea of sustainable building has been developed. Some understands the word of sustainable literally and strictly and tries to disseminate the examples of autonomous buildings. Contrarily, majority understands sustainable building is less-unsustainable buildings. Radical and incremental innovation are being progressed in the process of diffusion of sustainable building. Building professions tend to apply holistic approaches rather than insisting on application of specific technology. Diffusion of sustainable buildings requires preparation of common yardsticks of environmental performance of building. Since early 1990s, BREEAM, LEED and CASBEE has been developed and disseminated as environmental performance assessment method of building. Those are market based assessment methods by which many stakeholders can communicate about better buildings from the aspect of environmental performance. Though the methods is too much outlined from the aspect of rigor theory of lCA, the method are well used in market place. Finally, the article introduces international standardization of environmental performance assessment method of building.
