Abstract

One of the important policies to reduce building energy consumption and greenhouse gases is ‘building energy efficiency certificate’ in Korea. However, there has been no systematic analysis on the acquisition status of the building energy efficiency grade. The purpose of this study is to analyze the certification acquisition data of residential buildings from 2013 to 2023, when certification status statistics were secured. 3,686 certified residential buildings were analyzed. As a result of the study, the number of certified residential buildings continued to increase from 181 in 2013 to 1,593 in 2023. The certification of grade 1 is the highest at 37.1%. The frequency of acquisition of grades 1+ and 2 is the next highest. Apartments were the highest certified building use at 95.0%. The number of cases of buildings of 10,000 m2 or more obtaining certification is 2,230 cases (70.0%). Many of the residential buildings in Korea are buildings of 500 m2 or less, and policy supplements related to the building energy efficiency certification system are required so that many buildings can be energy-efficiently constructed.
