Zero-energy home development in Korea: Energy-efficient and environmentally friendly design features and future directions

Zero-energy houses, one of the progressive types of energy-efficient homes, theoretically consume no energy for heating, cooling, or other daily activities. The purposes of this research were to identify representative experimental housing projects in South Korea and analyze their major features in terms of energy efficiency and environmental friendliness. This study used case studies consisting of two zero-energy experimental houses and one occupied zero-energy neighborhood. This study found that efforts have been made to build zero-energy homes in Korea. The study also found renewable energy systems such as solar and geothermal systems have been applied in zero-energy houses in Korea. The study discusses future research needs focusing on post-occupancy evaluations that should involve current residents to maintain energy-efficient housing performance. In addition, a holistic strategy to embrace design, development, and maintenance aspects of zero-energy houses should be established to promote this energy-efficient and environmental-friendly housing option for diverse resident groups.
