Energy and Environmental Features Make Homes Greener
The "green building" movement taking place in
the housing industry represents a kind of quiet revolution, but one that
nonetheless is bringing decades of research and development of environmentally
friendly construction techniques and materials to new home
construction.
Green building, the general catch-all word for environmentally sensible
construction, includes many aspects. It can include land use, development and
community design techniques that preserve natural features such as trees,
wetlands and open space. It can mean water conservation as well as energy
efficiency in heating and cooling systems, appliances and lighting. Many common
building materials, such as the lumber, decking, or paints and adhesives, used
in home construction, are greener now as well, since many of those materials
been engineered to be more resource efficient, have recycled-content, or have
low or no volatile organic compounds.
Green homes are built using a number of energy and environmental advances or
environmentally-sensible materials, including:
- longer-lasting roofs made of durable steel or fiber-cement coverings;
- wood products such as Oriented Strand Board that use smaller trees and
parts of the tree not previously used - these products have replaced plywood
for sheathing;
- windows with insulating glass and coatings that keep homes more
comfortable and energy-efficient;
- increased insulation levels in walls and attics and advanced sealing
techniques that make homes less drafty and reduce energy bills;
- passive solar design that captures the sun's rays and gives homeowners
'free' heat;
- tree preservation around residences that provides shade, reduces energy
costs by cooling the home and creates residential communities of lasting
value;
- landscaping with native plants that require little or no watering by
homeowners and reduce water bills for homeowners in dryer climates.
These are just some of the advances discussed in a new six-page publication
entitled "Building Greener, Building Better: The Quiet
Revolution,"
that the National Association of Home Builders (NAHB) and the NAHB Research
Center recently published.
Featuring a four-color cutaway drawing of a typical new residence, the
publication provides details on just how far the housing industry has come in
providing greener housing choices to the American home-buying public. In fact,
many new homes feature:
- appliances such as washing machines that use 45 percent less energy and
dishwashers that use 40 percent less energy than models manufactured in
1972;
- plastic lumber in decks that has helped reduce the use of redwood in decks
to 6.3 percent in 1999, and;
- greater overall energy efficiency. Homes built today are 100 percent more
energy-efficient than homes built in the 1970s. Builders and manufacturers
routinely provide consumers with insulated doors and windows as well. In
fact, the use of insulated glass windows jumped from nearly 68 percent in
1978 to 87 percent in 1999.
A Better Environment Around Your Neighborhood And In Your Community
Homeowners can also enjoy walking near more wetlands these days, because
builders are restoring these areas that protect water and act as wildlife
refuges for rare and endangered species.
Building greener neighborhoods also means working to remove outdated
regulations that make building more sustainable neighborhoods difficult.
Builders are breaking down regulatory barriers so they can create more
tree-laden bike paths, put in water-purifying ponds and lakes, and ensure that
pedestrian-friendly communities come with ample open space. Watch for the
introduction of Built Green Communities, a new program of the HBA of Metro
Denver that encourages more environmentally and economically sensible community
development.
With the help and cooperation of local government officials, we can make
further green building and green development a staple of new communities, homes,
townhouses, apartments and condominiums.
