Walls for Zero Energy Homes

Exterior walls provide large surfaces that are exposed to the elements and interior walls can become tunnels of air in through interior spaces.

Energy conservation with wall construction provide a variety of options such as:

• Minimum R-19 insulation
• Inspect insulation to eliminate gaps that result from remodels or settling insulation
• Consider advanced framing or insulated headers
• R-10 exterior sheathing can prevent thermal bridges
• Light pastel paint colors in hot climates can reflect heat on exterior walls
• Green walls or trees outside West windows  can also provide shade to reduce hot afternoon temperature rises
