Creating green buildings is an important means of protecting the earth"s environment, “zero energy consumption” buildings use renewable sources of energy such as solar,wind energy and others as a core energy ,it has been becoming one of the important aspect of the green building.This article according to tianjin binhai new area of the wind,light level of natural resources and actual utilization situation of Tianjin new eco-city intelligent business hall,put forward the construction of “zero energy consumption energy” mix micro grid alternatives,which object is the intelligent business hall,and use the HOMER software developed by New American Energy Laboratory (NREL) to simulation calculation and design,through comparising technology and economic feasibility of several different hybrid system,based on meeting the given load levels,we make the conclusion that under the optimal cost, the optimal configuration of the hybrid system is the wind/light/store mixed system.
