How Attic and Crawl Space Ventilation Can Improve Your Home’s Energy Efficiency

Green Solutions Ventilation

You need to be able to keep your home comfortable during the winter and summer months, but you also need to know that you’re not overpaying for the energy that it takes to do that. Energy efficiency is a key concern of many homeowners, and it’s important to remember that every part of your home affects its energy use. One important but often overlooked way to improve your energy efficiency is to ensure that your attic and crawl space have proper ventilation.

At Green Energy Solutions, Inc., our Portland energy experts can help you determine whether your crawl space and attic are properly ventilated, and we’ll be able to help you ensure that your home is always as energy efficient as possible.

How Does Ventilating the Attic Improve Energy Efficiency?

At first, it may seem strange that purposely allowing colder air to enter through your attic vents areas—where you’ve probably installed insulation—can improve energy efficiency, but in fact, it’s extremely important.

Sealing your attic properly will ensure that your home’s heating and cooling systems don’t send air to your attic, where it’s wasted. But in order for this to not cause other damage to your home, proper ventilation is necessary.

Here’s how it works:

  • During the winter months in Portland, allowing a natural flow of cool air to enter your attic will keep it cool while you heat your home, which prevents ice dams from forming on your roof (snow that melts off a roof from an attic that is too warm and then re-freezes at the gutters, causing an ice dam that can damage the roof).
  • Properly insulating and ventilating your attic will keep heat and moist air from entering your attic.
  • During the summer months, a natural flow of air in your attic prevents heated from staying in the attic and causing damage to your roofing shingles.

How Does Ventilating a Crawl Space Increase Energy Efficiency?

Sealing your crawl space can be a great way to improve your energy efficiency, but when you’re heating your Portland home in the winter, there may be some unintended consequences of a sealed crawl space. It’s common for condensation to form in the crawl space if it’s sealed while you’re heating your home, which can ultimately cause serious moisture damage and mold growth. Our Portland Insulators can help you properly ventilate your crawl space in order to maximize energy efficiency while minimizing any damage to your home.
