What You Should Know About Passive Ventilation

Heat and excess indoor moisture are common problems inside the home. And, while your HVAC system can deal with them, relying on it too much will drive up your energy costs. You should try to incorporate passive ventilation instead. When done effectively, this method not only keeps your home comfortable, but allows for better indoor air quality as well.

What Exactly Is Passive Ventilation?

This refers to non-mechanical methods that help bring cool, fresh air into your home while expelling warm and stale air out. Passive ventilation uses openings, such as windows, to make this possible instead. In fact, with well-designed passive ventilation, you can refresh the air inside your living space without creating drafts or letting out too much heating energy.  But to ensure you get the best results, you’ll need to take window size and placement into account.

How to Integrate Effective Passive Ventilation

You can, for example, install windows higher up inside a room. When cooling is required, all you need to do is open these windows to let warm, moisture-laden air out of your home. Leave them open for at least 15 minutes, about 5 days a week to ensure your home is well ventilated. Another thing: make sure you have windows installed on opposite sides of your home to draw air through and promote greater circulation. Passive ventilation also becomes more effective with the right window style. Casement and double hung windows are great for this.

If you have windows facing south and east, open them to allow cooling breezes into your home during the day. To keep the air moving, make sure to open the windows on the north and west sides or on the upper levels. Speaking of upper-level windows, make sure those are operable. As hot air rises, leaving windows on the upper floors offers a great way to ventilate your home, especially during the summer.

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."
