LEED (Leadership in Energy and Environmental Design) certification is increasingly adopted in South Korea as a globally recognized framework for assessing building sustainability, operational efficiency, and environmental performance. LEED is commonly pursued for office buildings, hospitals, manufacturing facilities, logistics centers, data centers, hotels, and large mixed-use developments, especially where international investors, multinational tenants, or ESG reporting requirements are involved.
