Green or Greenwashed?

Wednesday, July 1st, 2009

A green product or service is one that utilizes fewer resources, fewer toxic materials, and/or boasts a longer lifecycle. The effort and resources a company puts into the way it does business, uses raw materials, and energy to produce environmentally friendly services/products is one way to define a “green” company.

The term “greenwash” is what you get when a company or organization uses environmental trends to its benefit by lying to or misleading its customers. Greenwashing isn’t new — since the environment emerged as an issue in the early 1970s, there have been advertising firms trying to convince consumers that buying Brand X is the only way to save the earth.green-seal

Greenwashing is so prevalent these days that TerraChoice, an environmental marketing company, found in a recent study that 98% of green labels were false or misleading. And 23% of products making green claims carried an environmental badge with no authoritative meaning. The TerraChoice website www.terrachoice.com offers a list the “seven sins of greenwashing” — seven simple signs that should tip you off if a company is more interested in selling the earth than protecting it.

To avoid greenwashed products, learn about the products and techniques used by your home service providers before you hire them!  Ask questions! And don’t be afraid to tell them what you’re looking for – they might learn something new in the process and start using green products.  See our tips below on making eco-friendly selections on a few common household items.

Hiring a cleaning service?

When hiring a professional cleaner, you should find out what type of household cleaning products they use. Many cleaning products include harsh chemicals intended to disinfect and kill germs, but most of the time this is overkill. Unless you are cleaning up after raw meat or bodily fluids, these toxic cleansers are not necessary, and many cause dizziness, nausea, allergic reactions, and irritation of eyes, skin and the respiratory tract – imagine the impact on the environment! Drain, oven, and toilet bowl cleaners are some of the most hazardous products in our homes. toxic-cleaner

  • Drano: Ditch it for a proven healthier alternative like baking soda and vinegar, or a hire a plumber!
  • 409 all-purpose cleaner: contains Alkyl dimethyl ammonium chloride (wikipedia details).  Do you want this chemical on your kitchen and bathroom counters?
  • The Works: a toilet bowl cleaner containing 20% Hydrogen Chloride. The label states “Danger: Corrosive. Causes skin burns and irreversible eye damage. Do not get in eyes, on skin, or on clothing.”
  • Clorox “anywhere” hard surface™: a daily sanitizing spray, which advertises “gentle enough to use around kids and food”, but contains Sodium Hypochlorite (chlorine bleach). Bleach can cause respiratory difficulties, headaches, skin burns, loss of consciousness, and vomiting. People who already suffer from respiratory conditions such as asthma or chronic bronchitis should never be exposed to bleach. And the risks are compounded when the cleaners are used in small, poorly ventilated rooms, such as the bathroom.

Switch to using non-toxic cleaners on a daily basis, and remember to ask about products used by any hired home cleaning professionals you bring into your home. If they’re not willing to use non-toxic products, then protect your family and don’t hire them!


Painting your home?

Consider hiring a painter that uses low-Volatile Organic Compound (VOC) or zero-VOC paints and finishes. The type and amount of VOCs in household paint generally varies with the type and brand of paint, but some paint contains many VOCs, including benzene, formaldehyde, and toluene. The fumes from VOCs are known to cause headaches, dizziness, eye irritation, nausea, and even cancer. Paint brands these days contain anywhere from 250 grams per Liter of VOCs to 0 grams per Liter (zero-VOC).

If someone tells you that a low- or no-VOC paint is not as good as a higher VOC paint, tell them you’ve heard otherwise! There are excellent low-VOC and no-VOC paints from leading brands including Sherwin Williams, Kelly Moore, Valspar (Lowe’s) and Olympic (Green Seal Certified). For Green Seal approval, the paint must be low-VOC (50 g/L for untinted flat interior paint), not contain harmful compounds or heavy metals, and must be tested for scrubability, hiding power, and washability.


Carpets need cleaning?

When choosing a company to do your carpet cleaning, make sure that they use safe cleaners. Environmentally safe cleaners should not contain any carcinogens, should not be combustible, and should not be corrosive to the skin or eyes. Some carpet cleaners contain toxins that can be harmful to those who walk and play on them. You should also avoid any products that could be harmful to aquatic life or that contribute to smog or other pollution. Many eco-friendly cleaning products are non-toxic, biodegradable, and made from renewable resources (not petroleum).

Tip: The common “Rug Doctor” carpet cleaning system found at Lowe’s, Albertson’s, and other store uses the Oxy-Steam Carpet Cleaner (red plastic bottle) which contains chemicals that are irritants to eyes and skin. Do you really want this cleaner on the floors that your children and pets walk on?

Improve Your Home’s Energy Efficiency

Tuesday, December 30th, 2008

Where heat escapes from the average home

Replace the incandescent light bulbs with CFL’s – check…done.

Now what?  Many homeowners are asking exactly that question – as we learn and hear more about global climate change, an increasingly important question for many of us is what else can I do to help?  How can I reduce my carbon footprint?  What can I do to live a more sustainable lifestyle?  This week I discussed some potential answers to these questions with Sloan Ritchie, owner of Cascade Built, a green real estate developer here in Seattle.

There are a number of lifestyle and product choices you can make to help out – however, some are more available than others and some may be cost prohibitive at the current time; who ran out and bought the new Tesla all electric (and very expensive) roadster for Christmas?.  And we all won’t be moving into LEED rated homes anytime soon.  LEED rated homes are a rounding error in terms of market availability and these high efficiency, environmentally friendly dwellings carry a premium price tag (although that’s changing).

Having said all of that, you can still help out in your 1992 built, 2000 sq foot <fill in house type>.  Two words – energy efficiency.  Or more specifically heating efficiency.  Did you know that in the average home 50% of the utility/energy usage is for heating?  If you’re going to expend energy to heat the air in your home, you don’t want that same air to immediately find it’s way to the outside (and possibly cold) world.  I learned a new building term this week (thanks Sloan) – ACH or “air changes per hour”.  It’s a volumetric measure of how much air is replaced in your house in a single hour, presumably air from the outside.  A tightly built home has an ACH rating of .25 – .35.  An average house built today has an ACH in the 1.4 – 1.8 range.  An older, more “loose” house comes in around 2.5 or greater.  So, a tightly built (or updated) home, which by the way is a key element in LEED rated homes, makes better use of the energy expended by keeping much of that warm air in the house – which means using less energy to heat – which means you’re doing more than CFLs.

So for those of us that make up the majority of the homeowners and live in an average or older home, how can we improve our ACH?  Well, here’s a quick hit list to get you started:

  1. “air sealing” – the idea is to plug, fill or otherwise block pathways for the air to the outside world – under each faceplate for switches, electrical outlets, phone and cable jacks, install a foam gasket (watch a very short video here) to help prevent air from escaping
  2. While you’ve got the faceplates for various switches and outlets off, have a look to see if you’ve got gaps between the electric box receptacle and the framing.  If so, either caulk (if it’s a small gap) or pack with foam for larger gaps
  3. Make sure you’re windows are well caulked and that the caulk isn’t deteriorating; re-apply caulking as necessary
  4. Check the weather stripping on all exterior doors; if it’s either non-existent or deteriorating, replace it
  5. Take a quick look in crawl spaces, attics and any other non-heated spaces where you might have pipes – find the ones carrying hot water and insulate them.
  6. Make sure to change your furnace’s filter at least twice a year – similar to dryer vent cleaning, the more flow you have through your filters the more efficiently your furnace will run
  7. Next to heating, refrigerators are next in line for improvements in efficiency (and thus savings on the energy use front) – to help the refrigerator be more efficient, simply vacuum the front grill at the bottom of your refrigerator on a regular basis; you guessed it – more flow of air = better efficiency

All of these tips should be doable in a weekend after a trip to your favorite hardware store…  If you’re up for the next level of effort (and potentially investment), here are few more things to consider:

  • how energy efficient are your windows or doors?  Are there more efficient or performant windows available?
  • what about the level of insulation you’ve got in your walls and attic?  Although the builder of your house likely applied what was required at the time, it may be inadequate today, especially if you have an older house
  • Moisture prevention is another key aspect of proper home insulation; if you don’t have a vapor barrier or you have an inadequate vapor barrier between the walls/ceiling and your insulation, moisture can form where the warm air inside the house meets cold air outside the house (yep, you guessed it in your wall and ceiling spaces) – this is a sure way to reduce the efficiency of your insulation
  • what is the ACH of your home?  If you’d like to know, you can hire a professional home energy auditor to actually do a test and help diagnose where you’re losing precious air (using a blower door) or heat (using an infrared camera like the one used to take the picture above)

All of these items are very likely to require additional cost and you’ll probably want a professional involved in order to do it right.

Whatever path you choose, the effort you put into increasing the energy efficiency of your home will pay dividends – first through your own knowledge and peace of mind that you’ve done more than change the lightbulbs.  And once you’ve done a few of the items above, you’ll hopefully see the other type of green savings – that of saving $ on your utility bills.
