01	A001 The promotion of green building construction requires the company’s support, coordinate leadership and specific implementation of the managers. The use of passive, negative, and deductive attitude should not be used to treat green building construction technology. Managers should actively use a scientific management method and system’s thinking mode to instruct personnel to carry out green building construction.	Green management, project management, personnel management	Management class
02	A011 The BIM technology can be helpful for clear grasping the actual effect of green environmental protection materials and technology during construction which can be provided the basis for the subsequent resource consumption and environmental protection.	BIM Technical application	Technical class
03	A057 Many urban green building construction projects can be participated in the awards, which can be used to enhance the reputation of the company and increase the competitiveness of enterprises.	Project award	Influence class
04	A101 In order to meet the requirements of the government and the people, the contractors and construction units generally take some techniques to carry out environmental protection, such as sprinkling water at the construction site to control dust height, regularly perform noise detection on the site, in the construction site for sewage settings at the construction site, the sedimentation tank, reducing nighttime construction, etc for enhancing the corporate self-image.	Dust emissions, domestic sewage emission rate, construction waste water emission rate, noise index	Environment class
05	A135 Many construction workers do not understand the green construction, not familiar, and have no awareness of green construction.	Personnel management	Personnel class
