The most efficient way is to force cold air into the space while also forcing hot air out. The best way to do this is to have maximum airflow from one end of the house to the other, often by opening all of your windows and using multiple fans to direct the air. For example, an intake fan pulling air in at the north end and an exhaust fan pushing it out at the south end.
