Eco-friendly building incorporates a wide variety of concepts and strategies during the design and construction process. Eco-friendly materials, a vital component of sustainable building, come from renewable rather than nonrenewable resources. Such materials enhance the health and efficiency of homes, but they also promote conservation of dwindling nonrenewable resources worldwide and reduce the overall impact associated with resource extraction, including transportation, processing, fabrication and disposal of materials. (See References 1.)
Advantages
Homeowners reap many benefits from eco-friendly building materials.
Some of these advantages include reduced maintenance and replacement
costs over the life of the home, increased energy
efficiency and utility bill savings, improved personal health of home
occupants and greater design flexibility. (See References 1.)
Resource Efficiency
All eco-friendly building materials have resource efficiency in
common, a criteria they meet in a number of ways. Materials may contain
postconsumer or postindustrial recycled content, or they may be easy to
recycle at the end of their useful life. Others are harvested from
sustainably managed sources, often certified by third-party
verification. Some materials are locally harvested, saving money and
resources related to transportation. Others are salvaged, refurbished or
remanufactured. (See References 1.)
Indoor Air Quality
Eco-friendly building materials enhance the interior air quality of a
home by meeting one or more criteria. They can be low in toxins,
including carcinogens and reproductive toxins, as proven by product
testing. They may emit minimal levels of volatile organic compounds
(VOCs). Some do not promote moisture or the growth of biological
contaminants such as mold. A final criteria qualifying materials as
eco-friendly is that they require cleaning with only natural, nontoxic
cleaning products. (See References 1.)
Eco-Friendly Product Assurance
To ensure that products are eco-friendly, look for labels certifying
that the materials have been tested and meet specific standards.
Investigate individual certification companies to determine their
methods and requirements. A few certification programs include Energy
Star, Green Guard, Green Seal, Green Label Plus and Scientific
Certification Systems (SCS) (see References 2). Additionally, the U.S.
Green Building Council's "Green Home Guide" offers information, guidance
and recommendations for eco-home building products and on finding
professionals (see Resources 1).
