| Abstract |
This study compiles and analyzes main-certification records from Korea’s Building Energy Efficiency Certificate (BEEC) for non-residential
buildings between 2013 and 2023, covering variables such as year, grade, use, region, floor area, and applicant type categorized as public or
private. Annual certifications increased sharply from 75 in 2013 to 1,107 in 2023, representing a 14.8-fold rise. Non-residential buildings
account for 5,948 cases, or 61.7 percent of all 9,634 certifications. The certification rate grew from 0.072 percent in 2013 to 1.173 percent
in 2023, while the period-weighted rate remained relatively low at 0.476 percent. Grade distributions improved notably around 2016, with
higher grades, 1+ and 1++, comprising 57.4 percent overall and 71.6 percent during 2020 to 2023. Certifications are concentrated both
spatially in the capital region, which accounts for 59.6 percent, and by size in large floor-area bands of 3,000 square meters or more, which
represent 79.3 percent. Early growth was driven mainly by public-sector projects, but private participation expanded rapidly in later years.
Cumulative shares now stand at 59.2 percent for public applicants and 40.8 percent for private applicants, with faster relative growth on the
private side. By floor area, the proportion of 1++ grades declines as building size increases, while 1+ grades remain relatively common. This
descriptive and non-causal analysis provides baseline statistics to support post-integration evaluation and future policy design. |
