How Much Air Leakage Do Houses Need?
In general, houses are usually around 3-5 times leakier than what they need to be for ventilation purposes. All sources of ventilation should be controlled/filtered, as opposed to being uncontrolled. Different construction methods in different climates can produce very different air leakage levels but forced ventilation with energy recovery should be considered in homes that get to at least 7 air changes an hour at 50pa. Depending on where a building is located, dictates how thick insulation should be and what level of air tightness should be achieved. Energy bills would be extremely high in the winter and the air would be so dry that the occupant’s lips would be permanently cracked. So, to some extent the climate dictates what builders can get away with.
Whole House Comfort.
It will make your home more comfortable. Drafty windows and doors make for uneven heating throughout the house. So you end up with some places that are too hot and others that are too cold. Imagine your home heated evenly throughout so that you could put your bed right next to your windows.
One of the unexpected benefits of air leakage control is that it reduces the amount of noise entering the home from outdoors. Noise comes in through small holes in the building envelope which are the same ones that allow for air leakage. This is one of the first unexpected benefits that occur when people first move into modern energy-efficient home.
