Game Study of Building Energy Efficiency from the Perspective of the Life Cycle Based on System Dynamics

Construction occupies nearly a third of the total social energy consumption currently, and it's even more than 40% on the existing residential heating system in North China. There is an outstanding tendency of a higher dependence degree of imported energy in China, which will have a negative impact on the construction industry with an emerging global energy shortage. This paper will combine system engineering and game theory to establish models containing stakeholders involved in building energy efficiency to indicate key elements and strategies from the whole life cycle. According to model results, a consumption pattern of energy can be revealed to regulate relevant markets dynamically, which will lay the foundation for policy-making to bring Pareto Optimum.
