A method is presented to reduce the heating loss of cold air infiltration through external windows by using positive pressure ventilation. The infiltration energy consumption is adopted as the evaluation index of energy conservation. In terms of the index, the effect of positive pressure ventilation is analyzed on the cold air infiltration, and the method is discussed to reduce the infiltration energy consumption. Taking a building in Shanghai as an example, it calculates the value of energy consumption from additional fan running required by positive pressure ventilation. Then combined with the saving infiltration energy consumption, it analyzes the net energy savings by adopting positive pressure ventilation. The results show that a proper positive draft used is available to low the energy consumption of cold air infiltration through external windows.
