It’s hard to believe but 90% of existing American homes are under insulated. That means 90% of existing American homes are wasting money, energy and are not providing their owners with optimal comfort. In addition to this, they are also having a negative impact on the environment.
The numbers are derived from the 2009 Residential Energy Consumption Survey, which used methods developed by the Lawrence Berkeley National Laboratory to estimate insulation levels. Researchers at Boston University had already applied these methods as part of a study into potential energy savings and emissions reductions through increased insulation levels in family homes.
According to Dr. Jonathan Levy, Professor of Environmental Health at Boston University School of Public Health and the lead researcher on the Boston University team that conducted the study, “If all U.S. homes were fitted with insulation based on the 2012 International Energy Conservation Code (IECC), residential electricity use nationwide would drop by about 5 percent and natural gas use by more than 10 percent.” The study showed that by increasing insulation in U.S. homes across the country, not only did energy usage decrease but there was also a reduction in carbon dioxide emissions as well as other pollutants.
When addressing home comfort issues, most homeowners think of windows and doors first, and about sealing air leaks around those areas because they are the most visible indicators of home energy efficiency problems. What they don’t realize is that insulation has a much greater impact (up to three times as much) on the average home’s energy and comfort than windows or doors. Assessing a home’s insulation takes only a few minutes, and the resulting improvements can produce a significant increase to home comfort, as well as substantial reductions to home energy bills.
