JAUE2014-036 A study on environmental effectiveness of G-SEED through analysis of energy consumptionand CO2emission amount of environment-friendly certified apartment houses

Abstract

Buildings account for 30~40% of world energy consumption and 40~50% of world greenhouse gas emissions. Therefore, the energy saving policy in the building sector is very important. Many countries have the environment-friendly building certification system in place to minimize the adverse effect of buildings on energy control and environments. Korea is also enforcing G-SEED. Accounting for 40% of G-SEED certification records, apartments are Korea’s most common residential buildings and their G-SEED certification keeps on growing. However, questions are raised about not only the institutional aspect of G-SEED itself but also effectiveness of G-SEED certified apartments. Until now, there have been many theoretical analyses on G-SEED in Korea, but there are not enough studies on post-evaluation of G-SEED certified buildings and envi ronmental effectiveness of G-SEED. Therefore, this study compared energy consumption and CO2 emissions of G-SEED certified apartments and non G-SEED certified apartments to analyze the environmental effectiveness of G-SEED certified apartments.According to analysis result, it was verified that environment-friendly certified apartment houses used more energy and emitted more CO2.
