Even though its low cost and wide variety of colors and patterns make it a popular flooring choice, polyvinyl chloride (PVC) continues to be the subject of considerable controversy. Its production releases an extraordinarily toxic chemical—dioxin—and many, including the Healthy Building Network, consider PVC to be one of the “most environmentally hazardous consumer materials produced.”
Does Green Building Cost More?
It doesn’t have to. Many green building features and products cost the same as, or even less than, their conventional counterparts. Other green features may cost more upfront but result in savings year after year. Energy-efficiency upgrades, for example, usually pay for themselves by lowering your monthly energy bill.

The Forest Stewardship Council is an international organization whose certification process provides consumers with assurance that wood was harvested from well-managed forests and plantations. Be sure to look for the FSC label when purchasing wood. fscus.org
LEED Green Building Rating System
A national standard established by members of the US Green Building Council, it provides a framework for assessing building performance and sustainability. It is an acronym for Leadership in Energy and Environmental Design. usgbc.org
The release of vapors from a material; many materials in the home offgas formaldehyde and volatile organic compounds (VOCs). TIP: Interior plywood emits urea formaldehyde (a carcinogen)—use exterior-grade plywood instead.
Rapidly Renewable Resources
Don’t contribute to deforestation; instead, use products made from rapidly renewable resources that regenerate quicker than the demand for the products—bamboo and cork for example.
Volatile organic compounds are a range of chemical substances that become airborne, or volatile, at room temperature. They are found in paint, wood preservatives, aerosol sprays, glues, cleansers and disinfectants, moth repellents, dry-cleaned clothing, and even air fresheners. VOCs are a major source of indoor air pollution, exposure can cause symptoms ranging from nausea, eye irritation and headaches—just think of how your dog will feel being that much “nearer” to the source TIP: by choosing a zero to low-VOC water-based paint, you can really reduce, or even eliminate, this concern.
Here’s a quick chemistry lesson. Not everything with “organic” in its name is actually good for us. When we walk into a newly painted room, the first thing we notice—besides the lovely color—is the smell, which comes largely from VOCs, chemicals added to paint to speed up drying time. Choose low- or zero-VOC paints; interior flat paint with VOC level of 50 grams per liter or less, and interior non-flat pain with 150 grams per liter or less. VOC content should be labeled on the packaging. Note: that low odor does not mean low VOC, some manufacturers use fragrance to mask the paint odor.
