SEJONG, Jan. 2 (Korea Bizwire) – South Korea is streamlining its building energy efficiency evaluation system by integrating the Building Energy Efficiency Rating System into the Zero Energy Building (ZEB) Certification Program, the Ministry of Land, Infrastructure, and Transport announced on January 1.
The changes are part of the Third Green Building Master Plan (2025–2029), aimed at promoting carbon neutrality in the construction sector.
Under the new system, building owners previously required to obtain a “1++” energy efficiency rating before applying for ZEB certification can now follow a simplified process. The certification timeline has also been reduced from 80 days to 60 days.
For public buildings, the minimum ZEB certification level for new constructions has been raised from Grade 5 to Grade 4, reflecting a government-led effort to drive carbon neutrality in the building sector.
Meanwhile, private buildings, including apartment complexes with 30 or more units and structures with a total floor area exceeding 1,000 square meters, will be required to achieve at least Grade 5 ZEB certification starting in June 2025.
Efforts to mandate “green remodeling” for aging public buildings to reduce greenhouse gas emissions are also underway. However, implementing this measure will require revisions to the Green Building Promotion Support Act.
The plan includes enhanced energy-saving design standards for private buildings larger than 1,000 square meters and mandates that local governments develop green building plans within two years of the release of the national master plan.
“The Third Green Building Master Plan serves as a mid- to long-term roadmap for achieving carbon neutrality in the building sector,” said Jang Woo-chul, Director of Building Policy at the Ministry of Land. “Starting with the unified ZEB certification system, we are committed to implementing this plan effectively over the next five years.”
These changes underline South Korea’s dedication to accelerating the transition toward sustainable and energy-efficient construction practices.
