System dynamics model for life cycle assessment (LCA) of residential buildings

An evaluation method for life cycle energy (LCE) and CO2 (LCCO2) of houses by the  system dynamics (SD), a method for understanding how all the objects in a system interact with one another, was presented. The building design strategies to predict and reduce the environmental loads for the several types of construction and building materials were investigated. As a result of the simulation, the long-life and energy efficient house was more effective in regard to life cycle assessment (LCA) than the typical houses. Moreover, possibility of life cycle cost (LCC) of the houses and a carbon dioxide flow SD model were also addressed.
