Eco-Friendly Heating & Cooling
Four green building focus areas for your log home

Heating & Cooling
The key to comfort is managing moisture and working with your climate instead of against it.

Climate-based design varies with geography. For example, in the northeast United States, vapor barriers are installed on the interior side of the insulation, while in the humid South, they’re placed on the exterior to keep moisture at bay. In hot, sunny climes, roof overhangs shield a home from excessive UV rays. But in cooler regions, strategic window placement on the south side of the house will allow you to heat your home with solar energy.

Some home owners opt for more high-tech heating systems, such as photovoltaic roof panels, but Bob notes that these systems are expensive and may be unnecessary if other, more inert measures are employed (such as passive solar heating).

Another option is a geothermal heat pump. This system, which is installed beneath the house, takes advantage of the Earth’s relatively constant subterranean temperature to heat and cool your home. In the winter, it transfers heat from the ground to your home; in summer, it extracts interior heat and discharges it into the ground, keeping your home cool without air conditioning and related energy usage. Bonus: The right unit can double as a hot-water heater.
