Are log homes energy efficient? Most existing and new log homes (as well as conventional homes) are not energy efficient; however, they can be, reducing utility bills 30 to 80%. It is of utmost importance, not only to choose an experienced log home (or conventional) builder, but also one who hires an independent, 3rd party Home Energy Rater who plans, inspects, test, verifies and Certifies your new home to be energy efficient. "If your home is not tested, you really don't know." We offer ENERGY STAR Certified Homes that earn the government backed Blue ENERGY STAR Label and Certificate. Learn more . . .

National and state building codes added energy requirements (R-Values) in the 70's used to calculate the rate of thermal resistance, without considering thermal mass. In log homes, the thermal mass of the solid log walls retain heat more efficiently as the temperature falls, reducing heat loss. The National Bureau of Standard and Technology found that "log buildings use less energy than comparable insulated wood framed buildings."
