When talking about green building, energy efficiency, and passive solar design, you may hear
the term “thermal mass.” The term refers to the ability of a material to stabilize the temperature
of your home by storing heat from the sun (called solar gain) during the day, then slowly
releasing it at night. Some people add a thermal mass feature to help store solar heat, but luckily
for log home owners, logs themselves have considerable thermal mass naturally. Thermal
mass is difficult to measure, but there’s no question the thermal mass of logs help create a more
comfortable, efficient home.
