Indoor Air Quality Basics

Most of us tend to think of air pollution as something that occurs outdoors where car exhaust and factory fumes proliferate, but there’s such a thing as indoor air pollution, too.  Since the 1950s, the number of synthetic chemicals used in products for the home has increased drastically, while at the same time, homes have become much tighter and better insulated. As a result, the EPA estimates that indoor pollutants today are anywhere from five to 70 times higher than pollutants in outside air.

Luckily, there are many ways to reduce indoor air pollution. We all know that buying organic and natural home materials and cleaning supplies can improve the air quality in our homes, but there are several other measures you can take as well.

How pollutants get into our homes

Potentially toxic ingredients are found in many materials throughout the home, and they leach out into the air as Volatile Organic Compounds, or VOCs. If you open a can of paint, you can probably smell those VOCs. The “new car smell” is another example of this. The smell seems to dissipate after a while, but VOCs can actually “off-gas” for a long time, even after a noticeable smell is gone.

We all know to use paint and glue in a well-ventilated room, but there are many other materials that don’t come with that warning. For instance, there are chemicals, such as formaldehyde, in the resin used to make most cabinets and plywood particle board. It’s also in wall paneling and closet shelves, and in certain wood finishes used on cabinets and furniture. The problems aren’t just with wood, either. Fabrics—everything from draperies to upholstery, bedding, and carpets—are a potent source of VOCs.

The good news about VOCs is that they do dissipate with time. For that reason, the highest levels of VOCs are usually found in new homes or remodels. If you are concerned about VOCs, there are several products you can buy that are either low- or no-VOC. You can also have your home professionally tested.

How to reduce VOCs in your home

Make smart choices in building materials.

  • For floors, use tile or solid wood—hardwood, bamboo, or cork – instead of composites.
  • Instead of using pressed particle board or indoor plywood, choose solid wood or outdoor-quality plywood that uses a less toxic form of formaldehyde.
  • Choose low-VOC or VOC-free paints and finishes.

Purify the air that’s there.

  • Make sure your rooms have adequate ventilation, and air out newly renovated or refurnished areas for at least a week, if possible.
  • Clean ductwork and furnace filters regularly.
  • Install air cleaners if needed.
  • Use only environmentally responsible cleaning chemicals.
  • Plants can help clean the air: good nonpoisonous options include bamboo palm, lady palm, parlor palm, and moth orchids.
  • Air out freshly dry-cleaned clothes or choose a “green” cleaner.

Fight the carpet demons.

  • Choose “Green Label” carpeting or a natural fiber such as wool or sisal.
  • Use nails instead of glue to secure carpet.
  • Install carpet LAST after completing painting, wall coverings and other high-VOC processes.
  • Air out newly carpeted areas before using.
  • Use a HEPA vacuum or a central vac system that vents outdoors.

Prevent Mold.

  • Clean up water leaks fast.
  • Use dehumidifiers, if necessary, to keep humidity below 60 percent.
  • Don’t carpet rooms that stay damp.
  • Insulate pipes, crawl spaces, and windows to eliminate condensation.
  • Kill mold before it gets a grip with one-half cup of bleach per gallon of water.

How an Investment in Green Technology Can Pay off for Today’s Homeowner

 

Studies continue to show that real estate buyers are willing to pay a substantial premium for homes that feature highly efficient, environmentally friendly “green energy” technology.

While the added value depends on the location of the home, its age, and whether it’s certified or not, three separate studies all found that newly constructed, Energy Star- or LEED-certified homes typically sell for about nine percent more than comparable, non-certified new homes. Plus, one of those studies discovered that existing homes retrofitted with green technologies, and certified as such, can command a whopping 30-percent sales-price boost.

Options include technologies that you may already be very familiar with, as well as some new breakthroughs that may surprise you:

Fuel cells

Fuel cells may soon offer an all-new source of electricity that would allow you to completely disconnect your home from all other sources of electricity. About the size of a dishwasher, a fuel cell connects to your home’s natural gas line and electrochemically converts methane to electricity. One unit would pack more than enough energy to power your whole home.

Past fuel cells have been far too expensive and unreliable. But Redox Power Systems, a company that’s planning to launch its first fuel cell later this year, is using new materials, claims they’ll be able to cut the purchase price by 90 percent, and predicts the associated electricity-bill savings will allow homeowners to pay off that purchase price in just two years’ time.

Wind turbine

A wind turbine (essentially a propeller spinning atop an 80- to 100-foot pole) collects kinetic energy from the wind and converts it to electricity for your home. And according to the Department of Energy, a small version can slash your electrical bill by 50 to 90 percent.

But before you get too excited, you need to know that the zoning laws in most urban areas don’t allow wind turbines. They’re too tall. The best prospects for this technology are homes located on at least an acre of land, well outside the city limits.

Cool roof

Cool roofs keep the houses they’re covering as much as 50 to 60 degrees cooler by reflecting the heat of the sun away from the interior, allowing the occupants to stay cooler and save on air-conditioning costs. The most common form is metal roofing. Other options include roof membranes and reflective asphalt shingles.

Green roof

Another way to keep the interior of your house cooler—and save on air-conditioning costs—is to replace your traditional roof with a layer of vegetation (typically hardy groundcovers). This is more expensive than a cool roof and requires regular maintenance, but young, environmentally conscious home owners are very attracted to the concept.

Hybrid heating

Combining a heat pump with a standard furnace to create what’s known as a “hybrid heating system” can save you somewhere between 15 and 35 percent on your heating and cooling bills.

Unlike a gas or oil furnace, a heat pump doesn’t use any fuel. Instead, the coils inside the unit absorb whatever heat exists naturally in the outside air, and distributes it via the same ductwork used by your furnace. When the outside air temperature gets too cold for the heat pump to work, the system switches over to your traditional furnace.

Geothermal heating

Geothermal heating units are like heat pumps, except instead of absorbing heat from the outside air, they absorb the heat in the soil next to your house via coils buried in the ground. The coils can be buried horizontally or, if you don’t have a wide enough yard, they can be buried vertically. While the installation price of a geothermal system can be several times that of a hybrid, air-sourced system, the cost savings on your energy bills can cover the installation costs in five to 10 years.

Solar power

Solar panels capture light energy from the sun and convert it directly into electricity. For decades, you may have seen these panels sitting on sunny rooftops all across America. But it’s only recently that this energy-saving option has become truly affordable.

In 2010, installing a solar system on a typical mid-sized house would have set the homeowner back $30,000. But today, that price has been slashed to an average of just $19,000. Plus, some companies are now offering to rent solar panels to homeowners (the company retains ownership of the panels and sells the homeowner access to the power at roughly 10 to 15 percent less than they would pay their local utility).

Solar water heaters

Rooftop solar panels can also be used to heat your home’s water. The Environmental Protection Agency estimates that the average homeowner who makes this switch should see their water bills shrink by 50 to 80 percent.

Tax credits/rebates

Many of the innovative solutions summarized above come with big price tags attached. However, federal, state and local rebates/tax credits can often slash those expenses by as much as 50 percent. So before ruling any of these ideas out, take some time to see which incentives you may qualify for at dsireusa.org and the “tax incentives” pages at Energy.gov.

Regardless of which option you choose, these technologies will not only help to conserve valuable resources and reduce your monthly utility expenses, but also add resale value that you can leverage whenever you decide it’s time to sell and move on to a new home.
