Innovative Housing Ideas That Might Inspire
by John Livingstone, Founder, GoingGreenResources.com
The need for homebuilders to build green has been made abundantly clear. "Ride the Green Wave or be Swept Away'" was one of the many environmental sessions offered at the last National Association of Home Builders convention. There are many great ideas and resources for going green in home construction. Recently the San Diego Gas and Electric Co. (SDG&E), invited the public to an open house to view an experiment on a 35 year old house. This 2500 square-foot, four bedroom home, had over $90,000 worth of upgrades. The company called this an "Xtreme Energy Makeover." The homeowners were chosen on the basis of a 2006 essay contest. Company officials described the new systems, individually, as being as much as 90% more efficient than older ones. They expect the greatest payback to come from the photovoltaic system that is expected to reduce this family's energy bill to zero. San Diego Gas and Electric Co. provided the following information on energy systems and fixtures, along with the retail cost, including installation, and the estimated percentage savings over standard products. There are these and many other ideas used in other types of homes, both new and remodeled. Some of these ideas are:

Framing a Green Home
by John Livingstone, Founder, GoingGreenResources.com
Sustainable development requires that one explore the social, environmental and economic impact of the decision when we apply these principles to construction materials. We ask ourselves: What is more sustainable, baked adobe block indigenous to the region, which generates local jobs, or lumber imported from the Pacific Northwest, which produces less costly point-of-purchase homes? Do we use 2" by 4" wood studs which come from younger trees or 2" x 6" framing from old-growth trees that, because of the width, allows for more insulation to be put into the walls? Like many questions when building in an in an environmentally friendly manner, there isn't a perfect answer. What we can strive for is both affordability and a responsible use of resources. We must take it upon ourselves to reduce construction waste, recycle as many building materials as possible and to introduce new framing techniques to save both money and lumber.
The National Association of Realtors in a July 2007 article entitled "What's New on the Green Scene" explained: “Timber framing requires significantly less lumber than the traditional "stick-built" housing and almost always incorporates [structural] insulating panels (SIPS), which keeps heat and air conditioning from escaping the house. There's less waste when large timbers are used, compared with conventional construction that produces sawdust and waste every time a 2-by-4 stud is planed, says Frank Baker, president of Insulspan and Riverbend Framing, part of PFB Corp. in Calgary, Canada. In addition, less energy is needed to power machines and kiln dry wood because timber framing uses freshly cut wood, he says. Timbers are prefabricated and arrive at the building site ready to be assembled, paring construction waste. Costs vary according to finishes selected, just as they do with stick-built housing.” The Role of a Solar Distiller in Providing Heated Water
by John Livingstone, Founder, GoingGreenResources.com
A solar distiller that provides two to three gallons of pure, sun-distilled water every day may be an option for your home. A solar water heating system might also be a possible major feature in your new home. A passive solar system is so named, as there are no moving parts. Water is preheated in the solar collector through an arrangement of 4 inch diameter copper tubes painted black and placed in a box covered by a double glazed, low-iron glass, before it goes into the standard water heater. The low-iron glass allows more sunlight to pass through the double-glazing that insulates the tubes at night. The hot water system is looped and insulated, and activated with a re-circulating pump, so that you don't lose water while waiting for hot water to come to the tap. These hot water heating systems have a quick payback on the investment. Additional water saving features might include plumbing to accommodate a gray water system and a rainwater harvesting system for landscaping purposes. Building a "True" Green Home for the First Time?
by John Livingstone, Founder, GoingGreenResources.com
There are many beautiful homes being built these days, incorporating features that qualify them as being green. These may include energy efficient windows, insulation, heating and air-conditioning systems, and more. However, there are some exciting concepts and resources for going green that can be used to build, or renovate, what some would call a "true" green home. Some of these concepts include. The smartest way to start using solar energy in your home is by using the sun to heat your water. Solar collectors on your roof use heat from the sun to directly heat water. This "pre-heated" water, then goes through your electric or gas water heater. This reduces the energy used by your electric or gas heater by 60 to 90%. Your solar water heater will pay for itself, long before its useful life is over, putting money in your pocket every month. The most widely used and well-known device used to generate electricity from the sun is photovoltaics or PV. Photo, as a photograph, meaning light, and voltaic as and volts of electricity. PV is silicon semiconductor technology similar to that used in computers.
Using electricity generated with solar takes a whole system, not just PV. PV modules convert sunlight into electricity in the direct current (DC) form. This electricity can be stored in a battery or goes directly to the inverter. The inverter is an electronic device that can convert DC electricity into alternating current (AC) electricity. AC is the form of electricity that most power companies provide to your home. The inverter also provides system protection and automation. Speak with your architect and find out if any of these concepts can be incorporated into your home. Upscale Goes Green: Homeowners Focus Increasingly on Sustainable Energy, Renewable Building Materials
By Aldene Fredenburg
A quiet revolution is going on in the real estate sector. Many successful professionals are putting considerable money into building their own dream homes, and many of those professionals are choosing to build according to green principles. Perhaps the first decision these new homeowners face is how to heat and cool their homes. Before even considering what sort of heating and cooling system they will choose, they need to decide on a design and materials for the exterior structure. Alternative building methods including rammed earth, straw bale, and flying concrete construction feature thick walls, often over a foot thick, which conserve heat in the winter and keep the home cool in the summer. Some homeowners are even opting for subterranean dwellings, using the natural insulating quality of the earth to lessen their need for additional heating. Even when opting for conventional wood structures, homeowners are choosing the latest insulation materials, which offer optimal heat conservation with little to no outgassing of toxic fumes. Energy-conserving heating systems, some of which create radiant heat from hot water pumped through pipes beneath the floors, save on energy; passive solar construction - homes with south-facing exposure and large windows - allows the sun to warm the home. Solar panels provide electricity for lights and electrical appliances, and gray water systems recycle used water for additional use in the home. Some homeowners in colder climates opt for wood- or wood-pellet-burning furnaces rather than the conventional oil furnace, installing modern furnaces designed to minimize emissions.
Green-building homeowners and more and more developers opt for natural and sometimes man- Those not in the position to design and build their own home still have the option of “greening” an existing home, using a wealth of safe, nontoxic natural materials. Conventional plywood, which is manufactured using urea formaldehyde, can be replaced with a number of new, safer materials, including “Plyboo,” created from bamboo. Kiln-fired clay tiles, wood from sustainable forests, natural, safe interior and exterior paints, and a host of other materials help create a clean, healthy home environment. Building and renovating green currently costs more than using conventional materials; some green builders estimate the difference at about 15 percent. However, recently wood prices have soared, and increasing transportation costs due to the rising cost of gasoline and diesel has impacted the price of building materials, so the difference in cost between conventional and green building may well even out. As it stands now, increasing numbers of prospective homeowners are willing to pay a premium for a home made of attractive, sustainable, and healthy building materials.
