10 Things to Know About Natural Ventilation in Your Home

As a homeowner, you want your home to be a safe, clean place. Part of maintaining a fresh space is paying attention to your indoor air quality.

What IS indoor air quality, you ask? It’s a measure of the health of our indoor air, taking into account certain pollutants that can be present. That can include chemical or physical contaminants, among others.

Examples most of us are familiar with include carbon monoxide tobacco, formaldehyde and even organic solvents!

But that’s why ventilation is so important!

Ventilation plays an enormous role in sustaining proper indoor air quality. In fact, without good ventilation, your home can trap in harmful pollutants that can cause damage to the interior of your house…and your health (1)!

Here’s a couple things that you should know about natural ventilation.

Let’s Get Started

  1. It’s one of three types of ventilation. In addition to natural ventilation, there is also spot ventilation and whole-house ventilation. As you can probably guess from the name, natural ventilation is the only one that occurs naturally without any assistance from a system (1).
  1. Natural ventilation is uncontrolled airflow. Unlike spot ventilation and whole-house ventilation, natural ventilation occurs in an uncontrolled manner when outdoor air moves from windows, doors, or cracks in your home (1).
  1. There are two types of natural ventilation. Wind driven ventilation and stack ventilation are both ways that natural ventilation can be employed in a home or building (2).
  1. Wind driven ventilation deals with a difference in pressure. This type of ventilation occurs from naturally occurring pressure differences caused by the wind, and these differences cause the air to naturally ventilate (2). Pretty simple when you think about it!
  1. Stack ventilation also deals with pressure differences, but with a different cause. Unlike wind driven ventilation, these pressure differences are caused by a difference in temperature and humidity (2).
  1. Homes can be strategically designed to increase natural ventilation. In the market for a new home? You might want to consider its design before buying (or consider what changes might cost you). Ridge vents, skylights, and other architectural details can maximize natural ventilation (2).
  1. Windows are best to be placed on the north and south sides of your home. Did you know that window orientation can affect your home’s ventilation? If you have a say in the placement of your windows for a new home, this design will optimize cross-ventilation (3).
  1. Poor ventilation can affect your health. Without proper ventilation, excessive moisture can become trapped inside your home and cause a threat to your health. It can lead to mold growth and even ruin your insulation. In addition to becoming a welcoming environment for excess moisture, your home can also seal in harmful pollutants such dander, pollen, dust, and even carbon monoxide—yikes! (1)
  1. You should open your windows more often. Many people avoid opening their windows for a few reasons: noise, dust, etc. However, allowing some fresh air into your home will do more than you think. If the weather’s nice, crack a window open and allow some for some ventilation (3).
  1. Natural ventilation can save you money. Who doesn’t love saving money? When ventilation occurs naturally without the help of a mechanical system, you’re saving money on your energy bill! (3) Continue to look for ways to improve the natural ventilation in your home—you’ll thank us later.
