According to the idea of the life cycle assessment method (LCA), the consumption of the energy and material, which is involved in the whole life cycle in each phase of single green construction technique, and the impact on the environment, is discussed. Based on the fuzzy comprehensive evaluation theory, a green degree evaluation system is established. The Analytic Hierarchy Process method (AHP) is adopted to establish green assessment system of the hierarchical structure model, and by means of 10/10-18/2 scaling method through pairwise comparison on tectonic judgment matrix of each level, the weight of each affecting factor is ultimately determined. Finally, VB program is used to compile visual programs of green degrees assessment. The quantitative assessment of integrated green degree for green construction technology is obtained, after inputting the score of the corresponding index, with reference to the influence of the factors assessment standards. By verifying rationality of the assessment system, the study proves that the system plays a guidance role in the self-assessment and reasonable construction for the construction of green technology.
