High Environmental Quality is a French approach. It aims at limiting the environmental impacts of a building or a rehabilitation operation at short and long term, and at guaranteeing healthy and comfortable living conditions for occupants. A certified building can attain one of four levels: Good, Very Good, Excellent, Outstanding.



BREEAM is the British reference in terms of sustainable building and has become the standard method of assessment used de facto for describing a building’s environmental performance. A certified building can attain one of five levels: Pass, Good, Very Good, Excellent, Outstanding.



LEED is a North-American system for standardising buildings of high environmental quality. A certified building can attain one of four levels: certified, silver, gold or platinum.



The "Green Building 3 stars" Chinese label is handled by the Ministry of Housing and Urban and Rural development. Buildings are certified by China’s ecological label office at the China Green Technology Center.

As a first step, the building can be awarded the "Green Building Design“ label, which allows the building to be commercialized as a green building. Then, in the second phase, the building may be awarded the "Green Building Operation“ label.
