Abstract: Because there has been a dramatic increase in greenhouse gas (GHG) emissions from human activities in recent decades, the climate and environment can be getting worse. Therefore, the United Nations Framework Convention on Climate Change was created and a series of treaties were made to limit the amount of GHG emissions from various countries. The building sectorhas become the largest contributor of GHG emissionsaffecting the environment around the world. It is suggested that 30% to 40% of the total energy consumption comes from the building sector worldwide and this ratio is increasing continuously [2]. Consequently, the building industry from various countries has gradually recognized the importance of green or sustainable concept and embedded this ‘new idea’ into their construction projects. Green buildings (GB) are considered as a holistic method to mitigate climate change, protect both the environment and human health, sothey would certainly become an important development trend worldwide. However, at the current stage, the development and construction of GBhas encountered variousdifficultiesand challenges, which should be classified and tackled effectively. Only then will GB be developed in a good way.
