SEOUL, Jun. 22 (Korea Bizwire) — South Korea’s tallest skyscraper built by retail giant Lotte Group received a green building certificate from a U.S.-based environment organization, Lotte Corp. said Wednesday.
The 123-story Lotte World Tower received a Gold rating in the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) system, the conglomerate said.
LEED is a green building rating system that gives certifications based on various criteria from energy efficiency to indoor environmental quality, the USGBC said.
Lotte Corp. said the skyscraper self-produces about 15 percent of all energy used in the building via various technologies, including wind power and solar generation.
The certified 555-meter-high building consists of office space, lavish residences, a luxury hotel named Signiel Seoul and a glass observation deck.
