【Abstract】 This paper studied the incremental benefits of energy-saving in green building project of whole life cycle and analyzed the comprehensive benefits and the calculation methods,established the objective function model that included the incremental cost minimization and the incremental benefit maximization of green building energy-saving scheme. And the genetic algorithms was selected by comparing and analyzing the commonly used optimization algorithms,designed energy-saving schemes and obtained the optimal solution of maximizing incremental benefits of unit incremental cost based on De ST energy consumption value about various technologies by case study. The results showed that the ideal incremental benefits came from reasonable and effective technology combination and air-conditioning system and lighting system,the optimization results of energy-saving schemes depended on the benchmark return rate directly. This study could present the optimal energy-saving technology combination for decision makers.更多还原
