| Abstract |
To alleviate global warming effect, apartment house with long life spans have gained attention due to their ability to conserve resources and reduce CO2 emissions. The purpose of the study was to develop a Sustainable Durability Design method that can quantitatively evaluate LCCO2 emissions based on the durability life of apartment buildings in the early design phase. To compute CO2 emissions as a function of the durability life, the durability life was determined using the durability chapter of Korea Concrete Standard Specifications, computed W/B, and thickness of concrete cover. The life cycle of the building was divided into 4 phase. For the construction phase, major CO2-emitting construction materials were selected, and CO2 assessment plans for 5 standard apartment housings were proposed. For the operation phase, CO2 emissions were computed using the heating load calculation. For the maintenance and management phase, maintenance methods were selected according to the durability life, and CO2 emissions from repair materials for each maintenance method were computed. For the disposal phase, individual CO2 emissions were computed using the Standard Quantities As a result, design specifications that satisfy specific target durability life and target reductions in LCCO2 were selected in the early design phase. In addition, by conducting a case analysis, 36 design specifications were selected to obtain a durability life of 100 years and a reduction in LCCO2 emission of 40%. |
