Most homeowners rely on their air conditioning systems for indoor ventilation, sometimes overlooking an important resource: windows! In today’s post, Renewal by Andersen® of Greater Philadelphia discusses how natural ventilation works and recommends the best windows for it.
How Natural Ventilation Works
Natural ventilation utilizes air currents without the use of fans or other mechanical means. Air currents are created through pressure differences between indoor and outdoor spaces by opening two windows. As one window releases stale indoor air, it creates negative pressure that pulls fresh air through another window. This same principle is used in roof ventilation, where exhaust vents at the ridges release hot and humid air, and the resulting pressure difference pulls cool air through the soffits.
The Benefits of Natural Ventilation
Switching to a natural ventilation system when the weather is fair means you can turn off the AC. Heating and cooling takes up as much as half of an average household’s utility bills. A few days without it can help you save on your utility bills.
Natural ventilation also helps flush out all manner of indoor air pollutants like dust, mold and volatile organic compounds (VOCs). Regularly ventilating your home for at least 15 minutes a day can help maintain a healthy indoor environment.
The Best Window Styles for Ventilation
While any operable window style provides ventilation, some styles are better suited for certain rooms. This is something you should consider when choosing replacement windows:
- Casement Windows — Casement windows are suitable for large rooms because they tend to be manufactured in larger sizes and they swing open like a door. Two casement windows, ideally situated at opposite ends of a room, will allow plenty of ventilation.
- Sliding Windows — With sliding windows, you can easily adjust the amount of airflow just by sliding the sash. Our sliding windows have removable sashes that let you utilize the entire window area for maximum ventilation.
- Double-Hung Windows — Double-hung windows are ideal for small- to average-sized rooms, particularly those that can fit only one window. You can open both the top and bottom parts of a double-hung window to create the intake/outtake necessary for good ventilation. The upper opening releases stale air, while the lower opening takes fresh air into the room.
