Weatherization
Home weatherization is the process of modifying a home to seal it from the elements better, improve energy efficiency, and create a more comfortable and livable environment. According to the U.S. Department of Energy, air sealing and insulation improvements can save up to 20% on annual heating and cooling expenses (Source: energy.gov/energysaver/weatherization). Furthermore, weatherization enhances indoor air quality and adds value to a home or property.
The U.S. Department of Interior’s Guidelines on Sustainability for Rehabilitating Historic Buildings suggests weatherization to preserve as much of the original property as possible. Properties that are Certified Historic Landmarks or part of the National Register of Historic Places must follow these guidelines or risk losing their financial incentives.
Weatherization Process
The first step in weatherizing a home is conducting an energy audit to identify areas for improvement. For residential homes, a professional energy audit may cost between $200 - $700 and will involve a full interior and exterior assessment of your home. Professional energy auditors have the tools and experience to create a complete picture of your home where it can be improved; however, a DIY assessment can still provide valuable information.
This includes inspecting insulation levels and locating air leaks. Although what is feasible depends on the property, common weatherization measures include:
Upgrading insulation in attics, walls, and floors
Sealing air leaks (Weatherstripping)
Improving ventilation and moisture control
Resources and Financial Assistance
The Weatherization Assistance Program (WAP) is one resource available to help low-income households improve energy efficiency. Administered by the U.S. Department of Energy, WAP provides weatherization services to eligible homeowners at no cost. Other financial incentives, such as rebates or low-interest loans, may be available through local utility companies or government program
