Secondly, the simulation tool and how to use this tool simulate our real case are introduced.

Then, the summer case is investigated by this tool after the model is proved to be validated.

Finally, the improvement of establishing a better indoor environment is raised and the results of improvement and conclusion can be found. The final result will show the optimal solution that discovered by this study after compared different alternatives carefully.
