Abstract
In order to prevent the global warming, many countries have performed the Green Building Certification Systems headed by the developed countries. G-SEED is the representative certification system in Korea for constructing Green-Buildings as other countries' LEED, BREEAM, CASBEE, GREEN STAR etc. G-SEED was established started in 2002 and has been revised several times, still has problems regarding the appropriateness of articles weight and eco-friendly efficiency of Green Building. To confirm the G-SEED effectiveness for reducing Green House Gas(GHG) emission, we suggested how to calculate the amount of the carbon dioxide emissions. In this study the amount of carbon of the green buildings certified through G-SEED is computed and analyzed. Calculating and analyzing the amount of carbon emission of 68 certified Green Buildings(apartment houses), there was a little correlation between the Green Building grade and the amount of carbon emission. Therefore it was verified that there is a little effectiveness of the green building criteria in reducing GHG emissions. The reason is that there is a few criteria of calculating the GHG in Green Building Certification, and it is needed to revise the criteria that can verify the effectiveness of Green Building by evaluating the performance quantitatively. It is not affordable to give it a rating through evaluating quantitatively the carbon emission of buildings. It is also important that green building has to give us the qualitative satisfaction of the environment and phychological comfort. If G-SEED is well coordinated by the part of quantitative assessment and qualitative assessment, the sustainable buildings could be widespread to our living places without wasting the resources of future generations or degrading the environment.
