A Solid Green Foundation

A Green foundation is the point at which your home connects with nature. We’re talking: cold, moisture, and pests. You can deal with much of the cold aspect by using good sealants and thorough caulking. This is not a typical concern for a new homeowner, but as a Green home builder, you will want to monitor everything, especially where energy loss can occur.
Trying to include recycled materials in the foundation of your green home can also make a huge difference in cost and in your impact on the environment. Persuade your builder to work with you on locating recycled CMUs or at least using recycled concrete aggregate as a coarse fill below grade. (Take care to avoid moisture problems around your foundation; this is nothing new to green home building.) You can also specify recycled content in your concrete, such as fly ash and slag. Take this opportunity to install insulation for your concrete forms.
To avoid pest problems, and the later use of environmentally harmful pesticides, make plans now. Use permanent pests shields – especially termite shields – around the perimeter of the house. Employ plastic and metal dividers and fasteners to separate wood and concrete along the perimeter of the foundation from the surrounding ground.
And while you’re at it, protect your foundation from invasive roots by moving your shrubs and trees at least 3 feet from the house perimeter. A green home or any other can’t be happy without a sound foundation. These efficient building practices can be applied to any house plan.

Efficient Floor Plans

Not every pre-designed or stock home plan comes with "Green" features and Energy Savings.
But, you can easily add features and products to the plan to make it "Green" and efficient. You can also incorporate "Green" ideas in the planning stages beginning with your site work. For example, the first thing to consider is how your new home should be positioned on your lot. This is sometimes referred to as the "smart" or intelligent “Siting” of your new home. On every conceivable lot, there are bearings in which to face the house for improved energy performance and thus increased comfort. The primary objective should be to plan the site in regard to the path of the sun. Also to be considered are prevailing winds, but to a lesser degree. The next thing you should consider is perhaps changing the exterior wall thickness from 2x4 studs to 2x6 framing. While the additional strength of the thicker wall would be a plus, the big benefit for your family will be the extra insulation, and the reduced energy use for the life of the home. However, there are now certain types of insulation that can give you higher R-values in 2x4 construction which equal that of 2x6. You should consult with insulation companies regarding this. You might even want to change your house plan to specify Structural Insulated Panels (SIPs) in the construction of your outside walls. The energy performance of these products is miles ahead of stud framing of any kind and should be a “Green” change to be considered. So, the simplest and most effective measures you can undertake to "Green up" your house plans are: Site the house "smart" in relation to the sun, and revamp your exterior walls to either SIP's, 2x6 construction, or new types of insulation so that additional R-values are part of your home’s future.
