Changes of the micro-climate and building cooling load due to the green effect of a restored stream in Seoul, Korea

Cities all over the world have been warming up in the summer over the years. Seoul, Korea, is also an example of how a city was transformed into an urban heat island. Green areas produce social, economical and environmental benefits in highly populated urban areas. This study is to investigate the micro-climate changes and urban-scale cooling load reduction by the recently restored Cheonggye stream, also known as Cheonggyecheon, in Seoul, Korea.
