Research on Comprehensive Environmental Assessment of the Built Environment

Renewable  Built  Environment

Background and Purpose

　In recent years, as various urban environmental issues, including the heat island phenomenon, have become increasingly severe on a global scale, reducing CO2 emissions—identified as a primary cause—has become a shared societal challenge. Recognising the importance of life cycle CO2 assessment as one approach to reducing CO2 emissions, research is progressing across multiple fields. This study aims to establish a method for comprehensively and centrally evaluating the life cycle CO2 of elements constituting the built environment.

Results

　This study conducted an LCCO₂ assessment of a single residential block as a comprehensive environmental evaluation of the built environment, confirming that building refurbishment, densification, and proactive greening of land are effective in reducing the environmental impact of the built environment. Currently, assessments are being conducted on individual urban blocks and using multi-criteria evaluations encompassing biodiversity and acidification.
