Green building implementation has become an unavoidable trend in the growth of the construction sector, as China’s philosophy of “innovation, coordination, green, openness and sharing” deepens. Green construction, as the process of creating green structures, is essential to the buildings’ overall greenness. An extensive assessment of the three components of building planning, design, and construction, known as a “green construction evaluation”, so as to establish a set of green construction evaluation systems that meet the times’ development needs, saves resources, protects the environment and people’s better lives, and paves the way forward for improving building greenness and promoting green building development. In order to build a scientific and ideal green construction evaluation system, this paper will establish an index system focused on green buildings and prefabricated buildings. It aims to demonstrate the path for the development of green construction and encouraging the industry’s steady advancement.
