Green Options

Even in a Greencentric city like Berkeley, locals and Bay Area visitors would be Green with envy when they see the just opened David Brower Center. It feels healthy just to walk through the Green down-to-the-bones building which combines advanced technology along with simple recycled materials.

When entering for their housewarming party we had a difficult time not noticing the soaring concrete walls which made us think more dot com than gallery. The fact that in creating a building with an oh- so-feathery carbon footprint (when compared to most structures) Principal Architect, Daniel Solomon included up to 70 percent slag in those walls.

Building with reclaimed building materials is a great way to reduce the environmental footprint of a building. LEED and GreenPoints both award points for use of reclaimed materials. However, some reclaimed materials can be radioactive.

Last fall, Cathy Woods removed her Jupurana Bordeaux granite counters because they were radioactive. She did not want uranium ore in her kitchen, and she did not want to breathe the radon gas emitted by the granite.

Erica Marcus declared, “I was basically thrown out of a showroom today for mentioning radiation to the owner”. She says, “This tells a lot about the industry knowing about what they are selling”.

Cathy Woods’ new granite counters were radioactive. They contained as much uranium as commercial uranium ore. The showroom that sold Cathy her Jupurana Bordeaux granite did not warn her that some granite is radioactive. When I contacted the salesman, posing as a customer, he assured me their granite “is no more radioactive than soil or water”. However, Cathy’s granite emitted gamma radiation at many times background. The radon gas emitted by the stone tripled the radon concentration in her kitchen. [...]

Panasonic is fast becoming a brand name not just for electronics but also for green building products.

Eco-Products 2008 recently held in Tokyo, showcased a series of award-winning green products and services. The E Floor from Panasonic was shortlisted for the awards. The Eco Product Awards is presented by four organizations including the Global Environmental Forum, a non-profit organization under the jurisdiction of Japan’s Ministry of Environment.

Sometimes being green means taking on the “less is more” philosophy. Such would be the case with the Cavallo Lodge over in Sausalito. For the recently opened lodge, about half of the current lodge rooms they converted from the previous officers quarters, military barracks and the like. But don’t think of this place like Full Metal Jacket but rather Organic Cotton Robe.

We visited there a few months ago for [...]

The Kitchen Cabinet Manufacturers Association’s Environmental Stewardship Program (KCMA-ESP) encourages cabinet manufacturers to go green in all aspects of cabinet production, from smart harvesting to a healthier final product.

If cabinet manufacturers built simply to qualify for LEED credits, they could use recycled materials or no formaldehyde in their final product, but cause enormous environmental destruction in their manufacturing process.  Rather than simply gauging the final product’s green-ness, the KCMA-ESP takes every step in a cabinet’s life into account.  How was the wood harvested?  How much energy was wasted in its production?   Were the wood shavings, sawdust, or scrap reused for fuel or some other purpose?  Does the final product contain any volatile organic compounds (VOCs) like urea-formaldehyde?

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.

Some sources of harmful emissions in the home:

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 [...]

Can your hardwood floors contribute to global warming?  Which hardwoods are certified by the Forest Stewardship Council?  Are some types of bamboo greener than others?  Eco Timber’s Eco-Friendly Flooring Guide is a valuable source for information on sustainable hardwood flooring and a must read for any green builder.  The Richmond, California based company has promoted responsible harvesting of timber and sustainable practices such as reclaiming and salvaging wood (their guide tells you the difference between reclaimed and salvaged wood) since 1992.

Topics in the guide range from legal and illegal logging and responsible forestry to the presence of formaldehyde and other volatile organic compounds in the wood and adhesives.  Eco Timber tackles every step in the process from subfloors to floor pads to the panels themselves.  Looking for a specific hardness of wood?  They’ve got a scale.  Do you already have a hardwood floor and want advice on green care and maintenance?  Eco Timber has a section on maintenance, surface scratching, and refinishing.
