Weatherize Your Home for Better Energy Efficiency

The Department of Energy estimates that you can save between 5 and 30 percent on utility bills by making energy-efficient upgrades to your home or business. Air leaks around places utilities enter a building, poorly sealed doors and windows and poorly insulated attics, walls and flooring reduce energy efficiency. This puts a heavier load on your heating and air conditioning system. Repairing leaks and adding insulation create a comfortable indoor environment. Weatherization also reduces fire hazards, improves indoor air quality and enhances property values.


Air leaks not only allow unconditioned air to enter the living space. Air leaks can also bring in moisture that could contribute to growth of mold and mildew. Although leaks are often from places where utilities enter a building, they may also be from structural problems such as degraded siding or poorly sealed doors and windows.

A home energy audit identifies sources of air leaks and recommends ways to fix them. Weatherstripping and caulking are easy, inexpensive repairs for a homeowner to do. Sealing air leaks can save up to 20 percent on utility bills.


Insulating unconditioned spaces provides a barrier between areas with extreme temperature differences. Energy Star recommends that attics in homes in Illinois be insulated with R-values ranging between R38 and R49. Floor R-values should range between R25 and R30. In Illinois, utility districts, counties and other organizations give rebates for air sealing and other upgrades that enhance energy efficiency.
