Abstract
Recently, many policies and regulations by the government toward sustainable building, low energy and green growth are being established and the implementations of the related measures are also being promoted in each field of the society. People's awareness for the environmental preservation has increased, and the efforts of the government and its people are needed for the development of green technology and the activation of green building dissemination. The environment-friendliness and energy performance of public buildings are enforced by the governmental regulations, but the regulations for the private buildings are insufficient. Also the level of the criteria of energy performance in Green Building Certification Criteria(GBCC) is much lower than the applied technological level to the buildings. Therefore, the scores of Energy Performance Index and new & renewable energy installation ratio of the certified green office buildings are analyzed and the improved GBCC criteria in energy parts are intended to be suggested in this study. From the analysis of the results of this study, it can be suggested to increase the use of new & renewable energy as well as the level up in energy parts of GBCC. Furthermore, we expect that the improved GBCC enhances the environment-friendliness and energy performance of private buildings as well as public buildings.
