建築分野におけるLCAの利活用の実態と今後の課題

抄録

The report aimed to clarify issues on utilization of building LCA in Japan and discuss ways to deal with them. First, over 300 Japanese and international papers related to LCA were reviewed and showed that, while many international studies adopted multiple criteria for impact assessment; almost all Japanese papers discussed LCA based only on analyses of energy consumption and CO₂ emission. Subsequently, a questionnaire survey was conducted with building LCA practitioners in Japan as respondents; which revealed that their purposes of assessments varied widely. The survey also clarified a number of key issues, such as guideline, inventory database, and software.
