Green Construction Alternatives Evaluation Using GA-BP Hybrid Algorithm

According to the characteristics of green construction, this paper defines the key indexes in green construction assessment system which includes resources utilization, environmental protection and construction management. It also builds up green construction assessment model in which relationships among indexes are established. Back Propagation Neural Network (BPNN) optimized by genetic algorithm (GA) is used to assess green construction alternatives. And a case study has been conducted in order to verify the adaptability of the model.
