Weatherization

What is weatherization?

Weatherization is the process of protecting your home and family from the elements. Weatherization takes place both inside and outside the home, and can also include projects in your yard. The goal of any weatherization project is to reduce convective heat transfer: the unwanted transfer of heat from one part of the home to another.

Heat loss in an average home

If you’ve ever caught a chill from being in a drafty room in the winter, you’ve experienced an unwanted convective heat transfer. The heat in the room is “escaping” and the air temperature is decreasing. In this case, you could put on a sweater. But a better decision is to address the room’s heat transfer with a weatherization project.

What does weatherization do?

An effective weatherization project will prevent convective heat transfer. The result should be a room with a stable and predictable air temperature. You and your family will notice the improvement right away, when your rooms are more comfortable in heating season and all year ’round.

According to the U.S. Department of Energy,

The benefits of weatherization begin with reducing the energy bills of recipients for a long period of time. Some measures, such as insulating walls or roofs, for example, can provide savings for the lifetime of a house—30 years or more. Other measures, such as making heating or cooling equipment more efficient, will provide savings for 10–15 years. On average, the value of the weatherization improvements is 2.2 times greater than the cost. (“What is Weatherization?“)

That’s a healthy savings for anyone!

Do it yourself weatherization projects

There are several weatherization projects that anyone can complete with a few basic tools and the right materials.

Weatherization rebate and assistance programs

  • Department of Energy Weatherization Assistance Program: The U.S. Department of Energy (DOE) Weatherization Assistance Program provides grants to states, territories, and some Indian tribes to improve the energy efficiency of the homes of low-income families. These governments, in turn, contract with local governments and nonprofit agencies to provide weatherization services to those in need using the latest technologies for home energy upgrades.
  • WAPTAC: Weatherization Assistance Program Technical Assistance Center is a detailed reference site for Weatherization Assistance Program professionals and homeowners who want to find the technical information about their programs.
  • The National Association of State Energy Officials State and Territory Energy Offices map has state contact information for homeowners interested in finding weatherization resources and programs in their communities.
  • Utility companies and co-ops often have rebates or low-interest loans available for homeowners who want to use home performance contractors for a weatherization project. Check the inserts in your billing statement, or the utility’s website, for information about available weatherization and home energy efficiency rebates and programs.
