Abstract: In this study, life cycle assessment analysis was examined for the insulation material applied to the external walls in hospital building in Balikesir. Optimum insulation thicknesses were calculated depending on different insulation materials such as glass wool, rock wool and polyurethane considering the combustion properties. Then, the life cycle saving (LCS) and life cycle total cost (LCT) values were calculated based on the energy consumption of the uninsulated and optimally insulated external wall for ten years life. Finally, CO₂ emission savings due to life cycle greenhouse gas (LCG) were estimated. Optimum insulation thicknesses were found to be 0.157 m for glass wool, 0.074 m for rock wool and 0.022 m for polyurethane.
