In Korea, the demand of information on LEED cost added through LEED certification is rising according to the increase in the number of LEED projects, However the data of LEED cost reflected on construction market and conditions of the Korea are insufficient. Therefore, this study draw LEED cost data on additional construction cost of graded LEED certification through performance improvement and design changes of office building in Korea. In conclusion, an additional construction cost ratio of LEED projects to the reference building is drawn as certified level; -0.08%, silver level; +0.40%, gold level; +2.57%, and platinum level; +5.79%. |
