Ventilation methods

Regularly bringing fresh air into your home is vital to ensuring that it's a healthy place to live - and good house design will account for effective ventilation from the outset. In most cases, houses are ventilated using either natural ventilation which relies on either heat rising out through the top of the house or wind passing through either side, or on mechanical ventilation like that provided by whole house fans or HRVs / ERVs. In many cases, a mixture of methods is the most effective option.

Air infiltration

In many cases, ventilation in a house is unintentional, and comes from small gaps and crevices. This kind of ventilation, in some cases, has a big effect on a house's air quality.

Mixed mode / hybrid ventilation

In many cases, the best way to ventilate a room is to combine two or more different techniques. See how mixed mode ventilation can help you ventilate for different needs.

Natural ventilation systems

This type of ventilation takes advantage of rising heat and strategically located vents to draw air up through the top of the house, and in through the bottom of the house.

Mechanical ventilation

Mechanical ventilation (or forced ventilation) takes advantage of fans to help draw air in a particular direction to control ventilation in your home.

Wind ventilation and cross ventilation

Wind ventilation, also known as cross ventilation, is a simple and effective way to take advantage of the wind to keep your home cool and regulate air quality.
