Abstract
The authors examine the evaluation methodology for life cycle assessment in analysis of scenarios with time dependency. The evaluation target was skeleton-infill (SI) housing, offering advanced proposal and practical utilization as long-lived housing, and diffusion simulation was performed. Dynamically-changing scenarios used were demand change in the floorage of the house and the CO2 emission factor in the operation stage references to number of people per household, and the evaluation covered a period of 105 years from 1995 to 2100. The effects of SI housing diffusion on LC-0O2 and demolition waste were estimated based on the results.
