Applicability study of dual-airflow window for different climatic zones

Taking an apartment building with the floor area of 80 m² and a villa of 200 m² as study objects, compares the influence of dual-airflow window with conventional triple-window and supply-airflow window of the same dimensions on building energy consumption in the different climatic zones. The results demonstrate that the energy saving rate of dual-airflow window is highest in the severe cold and the cold climatic zones.
