David Johnston, a “recovering contractor” and author of Green Remodeling: Changing the World One Room at a Time, says the key to an energy-efficient home is controlling the holes where air and moisture can escape. “There are lots of places where a little caulk and weather-stripping goes a long way,” he says. Additionally, homeowners should check the attic, especially areas near vents and chimneys where heat escapes.
