*2.1. Green Construction Measures Cost*

The Chinese government has proposed to levy green construction measures costs to improve the energy efficiency of construction. Green construction measures cost (*Cgc*) refers to environmental protection fees, which are used to reduce the negative impact of construction and consumption of resources under the condition of ensuring engineering quality and safety. The ratio of green construction measure costs to subengineering fees of an actual engineering project is shown in Table 1.
