Green Building Elements

While autism rates have been climbing at a frightening rate, its root causes have remained elusive.  Researchers at the University of California, Davis M.I.N.D. institute have concluded that the focus of autism research should shift away from genetics or accounting practices and toward the increase of toxic chemicals and infectious microbes in the environment, especially in the home. Since 1990, autism rates in California have increased 600 to 700 percent. The study, published in Epidemiology, suggests that environmental toxins like metals, pesticides, and infectious agents could play a large part in the increase.

The dramatic increase in autism rates in California has been attributed to several factors, including increases in families bringing autistic children into California and changes in how autistic children are diagnosed.  To address the first issue, the study only looked at California natives. The second issue, accounting practices, played a small part in the increase, but no more than 20% of the overall increase. Read the rest of this entry »

2008 was the year that saw elements of green building become mainstream and increased interest in green technologies.  But for those of us who are not building a new house or who don’t keep up with all the new technologies, there are many simple, inexpensive (or free) ways to green your life that you can do right now.  The result will be a more energy efficient, healthier, and more sustainable environment for you and your children.  Do yourself and you family a favor, take one or more of the following resolutions to go green: Read the rest of this entry »

Emissions and Indoor Air Quality

While sustainability and energy efficiency often dominate the green building conversation, the issue that can have the most immediate impact on your family’s health is indoor air quality.  Green building programs seek to limit your family’s exposure to Volatile Organic Compounds, or VOCs, that exist in some building materials and furniture.  Continued exposure to these VOCs has caused health problems ranging from headaches and nausea to cancer.  Green building programs like the US Green Building Council’s LEED for Homes and LEED for New Construction encourage builders to eliminate these emissions whenever possible.

If building green comes at a slightly higher cost it is because many of these harmful chemicals are so widespread that finding products without them can be a challenge.  In fact, it is the presence of these chemicals in some products that makes them cheaper, as in wood products containing urea-formaldehyde.

Those looking to improve the indoor air quality of their current house can make several changes that will significantly reduce VOCs.

As Bugs Bunny used to say “What’s up Doc?” In the newly opened chiropractic office the reply would be “green”, as in green building. Yes, green building continues its march into the homes and offices across America and some doctors realize that sustainable interiors means healthy patients (or at least healthier). Take for instance, the new Executive Express Chiropractic designed by Martinkovic Milford Architects and built by Peacock Construction. A small place to be sure but the designers make good use of space to mention the healthy additions.

When we entered, we couldn’t help but notice the curved leather wall. We even stuck our grills right against the wall to smell the leather. Yep, it smells like leather. It actually is. But the green minded architects didn’t lose their minds, they used EcoDomo, which uses real leather scraps from shoes, and other leather manufacturing facilities, then grind it into shreds. They use water and other natural binding ingredients (mostly natural rubber and acacia wood bark) then eventually deliver them with a sticky peel-off back that requires no off-gassing adhesives.

We never claimed to be interior decorators but we can appreciate the Maya Romanoff paper wall covering that smartens up the treatment area. The covering looks even smarter when considering that it comes by way of stamping rayon fibers on wet wood pulp, which produce an attractive wall covering that displays both texture and depth.  The wall covering comes from rapidly renewable materials, particularly Mulberry, and is 100% biodegradable.

The designers added several other green elements including:  Benjamin Moore Eco-Spec paint, the treatment room dividers come from the 3-form “full circle” line that uses a form of fair trade for the families in Nepal who helped raise the silkworms to create the striking panels, and even the artwork and mirror framing employs FSC certified wood.

One thing kind of bugs us. The marble countertops and shelves come from EuroStone which create these products from and combo of 90% recycled marble chips and a polyester resin as binding agent. Excluding the resin as a natural element, it’s walking a pretty thin line to claim that using marble chips from quarries would be considered green. If they didn’t mine the resource in the first place then no chips would exist.

Who’s next in the waiting room?

A new study in the December 2008 issue of the American Journal of Preventive Medicine suggests that an increase of green space in a neighborhood may decrease the chance for childhood obesity among neighborhood children.

In the study, researchers from the University of Washington, Indiana University-Purdue University and Indiana University School of Medicine followed more than 3800 children aged 3 to 16 over a two year period. Using satellite imagery, the researchers found that of the predominantly African-American and poor children studied, those who lived near greater concentrations of green space had a greater chance of lower body mass index (BMI.) Children whose activities were limited to streets and sidewalks faced greater risk of childhood obesity than those who had access to open spaces such as yards, parks, or vacant lots.

This study finds that what is good for adults may not be good for children. A previous study done by the same researchers found that higher urban concentrations led to less driving and more walking by adults, and a corresponding drop in BMI. Read the rest of this entry »

This post is a follow-up to The Fight Over Radon in Granite Countertops Heats Up, which will provide some background information on the granite/radon issue.

With the legion of both deniers and alarmists out there attempting to monopolize the discussion over the safety of granite countertops, it is difficult to find unbiased information.  Peruse the comments in the above post and you can see the discussion has devolved into name calling.  The deniers, many of whom work in the granite industry, blast any insinuation that granite could be dangerous as “fear-mongering” and put down the current research as “junk science.”  The alarmists, many of whom sell competing countertops, argue that consumers shouldn’t take the risk that comes with granite.  The truth, as with most heated arguments, can be found somewhere in the middle.

The air is going to get a little bit cleaner come January, 2009 - and that has nothing to do with a new presidential administration.  The California Air Resources Board’s dramatic Air Toxic Control Measure known as “the CARB rule” will go into effect January 1 and will, among other things, mandate a reduction in formaldehyde levels in composite wood products like particle board, hardwood plywood, and medium density fiberboard.  Manufacturers of composite wood products have less than four months to adapt to the new requirements or they will be unable to manufacture or sell their products in California.

Formaldehyde came into the public consciousness this past Winter as trailers used for Hurricane Katrina victims were found to contain dangerous levels - click here for those findings.  Urea-formaldehyde is a volatile organic compound that has been linked to health issues ranging from persistent eye and skin irritation to asthma to, in extremely high levels, cancer.  It has been practically banned in Europe, Japan, and Canada.  The United States Green Building Council awards LEED credits for buildings that have eliminated added urea-formaldehyde.  The inclusion of the word “added” is due to the fact that small levels of formaldehyde occur naturally in wood.  Urea-formaldehyde is used in composite wood as a drying agent for glues and adhesives, significantly speeding up the manufacturing process of the composite wood.  For this reason, non-formaldehyde composite woods will come at a higher price.  Add in the increased demand due to the CARB rule and the current limited supply of formaldehyde-free composite wood and we could see increased prices across the board for composite wood products like furniture, cabinets, moldings and millwork, doors, and many other products.  Read the rest of this entry »

Despite the narrowing gap in cost between green building and traditional “to-code” building, most builders and home buyers still perceive the green option to be significantly more expensive.  The reality is that due to increased builder education and an influx of affordable green building products, a building can be built green within the same budget as a non-green building.  According to Clark Wilson, CEO of Austin based Green Builders, Inc., “It’s our job as builders to find those green products that don’t drive up the price of the home.”  Rick Hunter of the St. Louis green building firm Sage Homebuilders agrees:  “With proper planning and a little experience, building green, even certified green, can be done for about the same cost. We are building certified green homes at the highest levels of certification for less than 1% cost increase.“  For an informative breakdown on how green buildings cost from 0 to 2% more than non-green buildings, check out “The True Costs of Building Green” from the folks at Buildings.com.

Now that green building is an affordable option, it’s time to change the way we frame the affordability debate.  Too long have supporters of green building been on the defensive, forced to justify the costs of building more energy efficient, healthier, more sustainable homes.  Instead of focusing on the costs of making your building green, let’s talk about the costs of not building green.

I remember reading the little placard on the bathroom vanity advising me to hang my damp towels with curiosity. We were on vacation and it was the first time I had ever heard of such a thing. We did this at home, but it seemed more practical - a way to avoid doing laundry each night. There was also a note about turning the lights out when we left our room. Little things.

We discussed the hanging of the towels and the turning off of the lights over a shrimp dinner that night at some tourist trap. I remember my mom saying that if we all do a little, we can do a lot. So I thought it was great when I heard of Florida Gov. Charlie Crist’s new executive order that requires state agencies and departments to hold meetings and conferences at lodgings that meet the new Florida Green Lodging standards.

Please visit an updated post on radon in granite countertops here:  A Rational Discussion on Radon in Granite Countertops

The Marble Institute of America better get ready for another round of fighting because the issue of radon in granite countertops is back. For the past decade, the MIA has been trying, with much success, to squash the rumor that granite countertops have the potential to add dangerous amounts of radon in the home. A new study being conducted by Houston area not-for-profit BuildClean is raising old fears about the dangers of granite countertops, and its preliminary results show that while most granite countertops in the study contain very little to no radon at all, the countertops that do contain radon have levels that are frighteningly high. While consumers can be secure in the fact that the vast majority of granite is perfectly safe, a small percentage is still in question, and no independent scientific study exists to assuage consumer fears.

The first issue of Solid Surface in 1995 explored the possibility that granite countertops may pose a health risk. Soon, the MIA issued their response, which attacked the credibility of the science involved in the study as well as the fact that the advertisers in the journal included companies that competed with granite countertop manufacturers. But one phrase in the response, a highlighted phrase no less, is troubling: “…actual levels of radon gas emmissions are so low as to be insignificant and generally represent no threat.” As a father, I don’t want to be assured that there is “generally” no threat to my family. I want to know there is no threat. And after BuildClean* found that 3 of 95 granite countertops contained harmful amounts of radon, would the MIA consider such a small number to be “generally” no threat? I’m sure the owners of those three countertops are not reassured. Read the rest of this entry »
