Explain how inside -outside air temperature difference affects air leakage in a building.
What will be an ideal response?
Inside-outside air temperature difference produces inside-outside air pressure difference, which affects air leakage through the building. Cold air is denser than warm air. Hence, it has higher pressure. So, when outside air is cooler than the inside air, it leaks into the interior replacing warm inside air. The opposite occurs when the outside air is warmer than inside air.
