Log Home Builders

Log homes and energy efficiency

Though they are not exclusively American, no other type of house conjures up the essence of American architecture the way a log house does. From modest utiliarian structures designed to survive the elements, Americans have, for almost four hundred years, designed, built, and modified log home designs as they moved west across North America.

The log homes of today have all the rustic appeal of their handcrafted predecessors as well as taking advantage of the latest in innovations in materials, design, and construction methods. They range from small weekend getaways in the North Woods to upscale estates in Jackson Hole, Wyoming.

There are many choices for a log home. You can build it yourself from scratch, build from a kit, or hire a builder who specializes in log structures. While log home kits have been produced since 1923, and many manufacturers customize designs for buyers, a builder can help you get exactly the home you want.

Though manufacturers promote the energy efficiency of log homes, not everyone agrees. Wall thickness´ range from 6-16 inches. The R-value (energy efficiency) of logs varies depending on the type of wood. At best, a 6-inch log would rate R-9. Compared with a fully insulated wood stud wall that would have an R-14 value, most log walls would need additional insulation to meet existing energy standards.

However, logs have substantial heat storage capability because they can take advantage of a thermal mass effect that standard construction does not. According to a 1982 study by the National Bureau of Standards, log walls gain substantial heat during the day and release that heat slowly at night which can compensate for low R-values, especially in mild, sunny areas of the country.

Each state handles log homes a little differently. California calculates thermal mass effect and R-value together to determine building code compliance. Other states, like Pennsylvania and Maine exempt them from compliance regulations. Between your state´s Energy Department and the U.S. Department of Energy, you can find the code standards that govern log homes in your state.

You can improve energy efficiency in your home by considering the following:

• type, size, and placement of windows
• building orientation
• size and type of logs
• increased insulation

Whether you choose a site-built custom home or a kit, a builder who specializes in log construction can help with adding passive solar features that will enhance your home´s energy efficiency and comfort.
