Energy-Saving House Design

Advanced House Framing

• The U.S. Department of Energy suggests that contractors use the Optimum Value Engineering (OVE) method of framing when building a new home. Several benefits are gained with OVE. Less lumber is required and more insulation is added to walls in this method. This means that the build costs less and the walls are more energy efficient. It eliminates insulation gaps at "T" intersections and improves corner construction efficiency. This method of framing improves the "R" value, or how well insulated your house is, by up to 30 percent.

Heating and Cooling System

• The heating and cooling system in your home needs to be efficient to save energy in the house. First, make sure that all systems purchased and installed are Energy Star-approved systems. Shop around for the most efficient models on the market. Also, make sure that all the ductwork installed into the house is properly sealed. Properly sealed ducts are 20 percent more efficient.

Orientation of the Building

• A newly designed home has the advantage of flexibility when it comes to the orientation of the house. A square house is best, because there is less heat loss over every square foot of wall. However, if you build a rectangular house, it should be situated with the long side of the house running east and west. This positions the house in a way that takes advantage of the sun during the winter and keeps the house cool in the summer.

Windows

• Windows are where 25 percent or more of a house's heat is lost. A house design should minimize the number of windows on the north, east and west walls. South windows should be present but need an overhang. This prevents excess heat from building up in the summer but catches lots of solar heat in the winter. Windows should be energy efficient, and all need proper sealing when installed to maximize energy savings.
