| Abstract |
In this study, the envelope system affected CO2 emissions in the construction and maintenance stage is developed and evaluated by LCCO2 analysis. Whole life process of building envelope systems is divided into construction, maintenance and demolition stage and LCCO₂ evaluation method was established by calculating CO₂ emission intensity of each stage. The U-value of the external panel system developed in this study is 0.161W/m2K and it is excellent 3 times compared to existing insulation system, 0.47W/m2K. The developed system reduced material usage and life cycle CO₂ emission. The LCCO₂ evaluation results of the wall system show that the CO₂ emission of developed systems is the lowest as 20.58 tCO₂. That of outside and inside insulation system appears 31.04 tCO₂ and 32.39 tCO₂. The LCCO2 evaluation results of 15-story apartment house(60 houses) considering thermal properties by location show that CO2 emissions of the existing system appear to 5,208 tCO2 and that of developed appear to 4,070 tCO2. So, life cycle CO2 emission reductions were the 1,138 tCO2 and decreased by 22%. |
