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 out gassing 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 manmade materials created from renewable
resources, materials which do not expose residents to health
risks. Vinyl, which is infamous for out gassing toxic fumes,
is rejected in favor of safer materials; hardwood flooring,
much of it harvested from old-growth forests, is replaced with
materials like bamboo, and cork, two renewable materials
providing two very different, attractive looks in flooring.
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.
