This study forecasts the growth potential of the zero-energy building and green remodeling market, outlining policies and tasks for construction companies to meet green building supply targets under the carbon-neutral scenario. The zero-energy building market size is estimated to be KRW 15 to 20 trillion in 2022, projected to reach KRW 93 trillion to KRW 107 trillion in 2030 with the full implementation of mandatory zero-energy building certification road map. The zero-energy building market is expected to grow to KRW 180.4 trillion by 2050, reflecting the requirement for all buildings to be constructed as zero-energy buildings in line with the carbon-neutral scenario. Green remodeling of existing buildings, totaling 2.95 billion to 4.82 billion ㎡ in floor area according to the carbon-neutral scenario, is estimated to create a market worth KRW 1,706 trillion to KRW 2,781 trillion from 2023 to 2050. Both zero-energy building and green remodeling are anticipated not only to achieve carbon neutrality but also to yield socioeconomic benefits such as technological innovation, job creation, improved residential environments, and income redistribution. Government initiatives, including subsidies, low-interest loans, tax benefits, and building regulation relaxation, are deemed essential for private building green adoption (97% of all buildings). Companies should focus on developing core engineering capabilities, building partner networks, and strategizing for future market growth.
