NEVER before has America had so many compelling reasons to preserve the homes in its older residential neighborhoods. We need to reduce energy consumption and carbon emissions. We want to create jobs, and revitalize the neighborhoods where millions of Americans live. All of this could be accomplished by making older homes more energy-efficient.

Let’s begin with energy consumption and emissions. Forty-three percent of America’s carbon emissions come from heating, cooling, lighting and operating our buildings. Older homes are particularly wasteful: Homes built in 1939 or before use around 50 percent more energy per square foot than those constructed in 2000. But with significant improvements and retrofits, these structures could perform on a par with newer homes.

So how does a homeowner go green? The first step is an energy audit by a local utility. These audits can be obtained in many communities at little or no cost. They help identify the sources of heat loss, allowing homeowners to make informed decisions about how to reduce energy use in the most cost-effective way.

Homeowners are likely to discover that much of the energy loss comes down to a lack of insulation in attics and basements. Sealing other air leaks also helps. This can be done by installing dryer vent seals that open only when the dryer is in use, as well as fireplace draft stoppers and attic door covers.
