Air Sealing Improves Whole-House Energy Efficiency

Last updated 4 years ago

By Diane, Pacific Aire Comfort Advisor,

Many homeowners are unaware of the importance of air sealing a home as one unit. By using a whole-house approach when sealing air leaks, you will find yourself saving quite a bit of energy, which translates to a lower cost for heating and cooling your home.

Increasing your energy efficiency
Making your home energy efficient is beneficial to both the reduction in the use of natural resources and your monthly energy bills. The problem is, many homeowners view every part of the house as a separate component.  But to really tackle the energy efficiency of your home, you must drop that archaic form of thinking and realize that your house, in some ways, is a living, breathing entity -- and a sum of all its parts.

Air sealing is one of the best ways to improve your home's energy efficiency. Whether it's caulking gaps in the attic or using weatherstripping on your doors and windows, treating the system that you call your house as a whole will greatly affect what you're trying to achieve. When you set out to seal the leaks occurring in your home, tackle everything at once -- from doors and windows to vents and ducts. By doing so, you will make great strides in increasing your home's energy efficiency, thereby saving energy and money.

Air sealing by the numbers
Every home has a number of areas where air leaks are common. According to the California Energy Commission, the breakdown looks something like this in terms of percentage of air loss:

  • Ceilings, walls and floors: 31
  • Ducts: 15
  • Fireplace: 14
  • Plumbing penetrations: 13
  • Doors: 11
  • Windows: 10
  • Fans and vents: 4
  • Electrical outlets: 2

Although these are separate areas, together they represent your house's air leakage as a whole. In order to perform air sealing, which will make your home more energy efficient, you must combine your efforts to stop energy loss in all of these areas, being aware of which ones are causing the most problems.
