Is Green Just a Fad?


An article on the ABC News website with the provocative title "Going Green: Fad or the Future?" suggests that while right now "green is the new black," the long term-prospects for the green movement are less certain to remain as strong and as much a part of public awareness as they currently are.

But are Americans experiencing "green fatigue"? The ratings for Live Earth, which was billed as a must-see event, were dismal. The American broadcast drew just 2.7 million viewers, making it the least-watched U.S. program on Saturday night. Despite its undeniable entrenchment in pop culture and media, some experts say that the current incarnation of the green movement is just another "We Are the World" moment that consumers and businesses won’t be able to sustain over the long term.

Of course, this perspective is coming from a media outlet (ABC News) for whom the number of viewers are the most significant measure of importance. But that may not be a reliable indicator of how influential the green movement is. There is a wide gulf between public enthusiasm for a green-oriented rally like Live Earth, and public participation in actual green practice in their daily lives. Small steps, in many cases, but a lot of people have started taking at least a few steps to green their lives.

My perspective lies with the building and construction industry. I see increasing numbers of ads and new product announcements from hundreds of manufacturers. I can’t begin to count the number of trade magazine editorials I’ve seen that begin along the lines of this one: "These days, it seems everyone is jumping on the "green" bandwagon — including many companies in [your industry here]." Green awareness has permeated the building industry from top to bottom. And, while not every new building is a new model of sustainability, green building practice is here to stay.

Green Building Tour: FCNL Building

<img src="http://www.fcnl.org/images/building/building_lg1.jpg" alt="FCNL" width="333" height="222" align="right" />Although there is a growing push for incresing sustainability for buildings, our nation's capital is lagging behind other cities when it comes to green buildings. Though there are over <a href="http://www.usgbc.org/LEED/Project/CertifiedProjectList.aspx?CMSPageID=244&amp;CategoryID=19&amp;">600 LEED certified buildings nationwide</a>, only 6 of them are in Washington DC.

The <a href="http://www.fcnl.org/index.htm">Friends Committee on National Legislation</a> is a Quaker lobbying group in Washington DC. Their building is the first &quot;green&quot; building on Capitol Hill. The building received <a href="http://www.fcnl.org/press/releases/green_building071307.htm">bipartisan congressional recognition</a> at an event last week. They are anticipating LEED certification (which normally takes a few months after the building is substantially completed), and the building has already received other accolades, including the Washington Chapter of the American Institute of Architects awarding a presidential Citation for Sustainable Design.

Green Building Elements: Decking

It's full-blown summer now, and people are spending more time outdoors on their patios and decks. So let me offer a summertime question for discussion. Which is better to use for an outdoor deck: wood, or a manufactured product (like Trex, Timber Tech, etc.)?

This is no more a black and white issue than most other green building questions. This can depend on the particular situation and the specific needs of a particular project. I'm not going to give you a definitive answer, because I don't think that there is one, any more than I do for most green building topics (other than greener is better).

First, there is the issue of material content. On the one hand, the manufactured products often use some combination of wood fiber (which is often sawdust and other scrap that would otherwise go to waste) and plastic (sometimes incorporating post consumer recycled material). On the other hand, wood is a natural material. It is sustainable, in that wood can be grown and harvested. There are some deck materials that have natural rot-resistant properties, but these tend to be more expensive. There is also the question of whether or not they are sustainably harvested, as well as the issue of shipping these materials.

Better Daylighting

<p><img src="/files/images/sol.jpg" border="0" alt="Advanced Glazings, Ltd." width="279" height="186" /><strong>solera : </strong>Image Credit: Advanced Glazings, Ltd.Lighting for buildings is a major part of their energy use. Increasingly, green building design is recognizing the importance of providing natural daylight as a means of lighting the building and reducing energy use. Not only does natural daylight reduce the building's energy use, but it also increases comfort for the people in the building. The LEED system includes credit for providing at least 75% of the spaces in the building with natural lighting and views, and the credit is increased if 90% of the spaces are naturally lit.<br /><br />Windows are good for providing views to the exterior. Skylights can be used to bring in more daylight, but they are not without issues. The problem with skylights is that they tend to create glare. The high contrast between areas where the daylight is streaming through the windows and other parts of the space that are not directly lit is visually (and sometimes even literally) uncomfortable. There's either too much light or too little. Diffuse light is more even and comfortable, and avoids areas of deep shadow and sharp glare. This is why so many older buildings had north oriented skylights or clerestory windows (or south-oriented in the southern hemisphere), and why those spaces were so well thought of as artists' spaces and galleries. The <a href="http://www.advancedglazings.com/ldp/index.php">light quality is much better</a> when it is from an indirect source.<br /><br />Most diffuser options do little to spread the light around. Typical etched or frosted glass has little effect. The light patterns are a little bit softer edged from frosted glass than they are from clear glass, but when it is directly lit, it is little better than clear glass. Advanced Glazings, Ltd. offers much better performance for incorporating daylighting into buildings with a line of insulated glazing called <a href="http://www.advancedglazings.com/index.html">Solera</a>. Architects have known of <a href="http://www.kalwall.com/windows.htm">Kalwall</a>, another company that has been making translucent panels for many years. Kalwall is a panel of polyester and fiberglass that offers translucency and some insulation.</p>

Weekly DIY: Pedal-Powered Clothes Washer

<p><img src="/files/images/saladspinner.jpg" border="0" alt="Homeless Dave" width="240" height="195" />Image Credit: Homeless DaveSome people looking to reduce their home power use may be interested in alternatives to the typical clothes washer and dryer. While the washer and dryer aren't the appliance with the biggest energy budget in the typical household (that distinction belongs to the refrigerator), an opportunity to save energy here may be something to consider. </p><p>The dryer is the easy part. A clothesline is about the simplest, cheapest alternative to a clothes dryer you can find. But the washer is harder. Hand-washing clothes is a difficult task. And wringer washers are a hand-operated option, but they aren't very efficient. A bicycle powered clothes washer is a more efficient, and much more ambitious project. While it's not likely that most of you will rush out to build one of these for yourselves, it offers a wonderful insight into how far you can take DIY if you are inclined to.</p><p>The pedal-powered washer was designed and built by <a href="http://www.homelessdave.com/abouttt.htm">Homeless Dave</a> (who is not really homeless, but whose real name <em>is</em> Dave), a local advocate for community and for human-powered tools in Ann Arbor, Michigan. His website, <a href="http://www.homelessdave.com/totterhome.htm">Teeter Talk</a>, features interviews with &quot;folks from Ann Arbor … Detroit … and beyond&quot; which are conducted on a teeter-totter in his back yard.</p>

Is Green Building an Oxymoron?

<p><a href="http://www.sfgate.com/cgi-bin/object/article?f"><img src="/files/images/greenenvy_0.jpg" border="0" alt="San Francisco Chronicle" width="200" height="200" /></a>Image credit: <em>San Francisco Chronicle</em>An opinion article by Jane Powell in the <em>San Francisco Chronicle</em> titled '<a href="http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/05/13/CMGA7PCMDH1.DTL">Green Envy</a>' begins by saying, &quot;'Green building' is the feel-good trend of the moment. Cities stipulate it, builders market it and home buyers supposedly demand it. Who could be against it? It's the panacea that will combat global warming, prevent sprawl, revitalize our downtowns, contribute to the region's economic growth and keep California on the leading edge,&quot; and goes on to declare, &quot;'Green building' is an oxymoron.&quot; <br /><br />I have a different opinion about green building. I spent all day yesterday attending a USGBC Technical Training Seminar, in order to become a LEED-accredited professional. To dismiss all green building as an oxymoron overlooks much of the good that is involved. Green building is not an oxymoron. Green building is taking steps for real change, improving the performance of buildings, and establishing methods for construction of buildings that will improve the spaces where we spend as much as 90% of our lives.</p>

Weekly DIY: Copper Garden Trellis

<p><img src="/files/images/rosetrellis_0.png" border="0" width="198" height="198" />A few years ago, when we started getting our garden together my wife wanted to have a trellis for some roses to climb on. We looked at various options. There are pre-built or kit trellises, but those are expensive. We could build one with wood, but it would need to be treated with preservatives (nasty chemicals) and would need maintenance. We ended up deciding to build one using simple copper pipe.</p>

The Greenness of Prefabrication

Living Homes (via Inhabitat)Photo Credit: Living Homes (via Inhabitat) Bob Ellenberg wrote a good, thought-provoking (and discussion-starting) article at Inhabitat titled 'Prefab Construction: Green or Greenwashing?' and drew comments from Preston Koerner (of Jetson Green) and Lloyd Alter (an architecture writer at Treehugger with whom I had some inter-blog discussion over the past couple of weeks regarding foundations, but more importantly also an entrepreneur in prefab construction with direct experience in the process).

Prefab is a popular concept in green design circles and shows up regularly on a number of blogs. A few of the more prominent examples include: Inhabitat (Pre-Fab Friday); Jetson Green; Treehugger; BldgBlog; MoCo Loco; and even a website devoted to prefabs: FabPrefab. But it's a valid question that is being asked. How "green" is prefab building, and should it be embraced by those who want a greener building? Bob sums his article up this way: "I want to honestly question what is and what isn't 'green' about prefabrication and encourage others to do the same."

Prefab construction can be very green. The LivingHomes prefab illustrating this article is a LEED Platinum building. But, there are very few examples of prefabs that have LEED certificaion. And not every prefab qualifies even as a LEED certified building, let alone a Platinum one.

Weekly DIY: Cold Frame

<p><img src="/files/images/coldframe-b.png" border="0" width="230" height="217" />This weekend we got the first tantalizing taste of spring as the weather was clear and bright and temperatures rose well above freezing for the first time in months. Snow melted (though not entirely yet), and started the <a href="/blog/2007/03/13/lets_talk_about_it_sustainable_gardening_tips">thoughts of summer gardens</a> in mind. But nighttime temperatures are still falling below freezing, and it's far too early to put plants in the ground, unless you provide a little assistance.<br /><br />If your garden has a spot with good access to the sun throughout the day, you can use a cold frame to start your plants earlier in the year than you would otherwise. A cold frame is a very simple item. It is really just a small greenhouse. Daytime sun will warm the air and the ground inside, making it easier for plants to start growing. Nighttime temperatures inside the cold frame may fall back close to outdoor ambient temperature, but the extra heat gained during the day and the wind protection the encosure provides will help keep the plants alive even if there is an overnight frost.<br /></p>

Green Building Tour: Kelly-Woodford Home

<p><img src="/files/images/KWhouse1.jpg" width="234" height="200" alt=" GRID Alternatives" />The first LEED for houses (LEED-H) project in the Northwest to achieve a Silver rating was the 2,000 square foot Kelly-Woodford Home in Parkdale, Oregon. The house was built by the <a href="http://www.neilkelly.com/">Neil Kelly Company</a>, a Portland area builder. The company has been a leader in environmentally oriented construction for a number of years.</p>

Climate Challenge Game


Modeling and simulation are good tools to use to understand a problem. They let you try out multiple approaches and different possible solutions to see what the results may be. Games can be an appealing way of presenting simulations. Complex ideas can be presented in a context that illuminates the difficulties of the situation. We learn by trying out different options. Multiple, interrelated factors can be more readily presented in an interactive fashion than in a dry recitation. Playing a game can be educational because we are more engaged with understanding what is going on (in the course of trying to figure out how to win) than we are when we are simply reading or hearing about something.

Vancouver Adaptive Reuse

<p><img src="/files/images/koos1.jpg" border="0" alt="cmhc.ca" width="339" height="243" />Photo Credit: cmhc.ca<br />Adaptive reuse is the use of an existing structure for a new purpose; in short, it is recycling for buildings. Rather than demolishing an old structure to clear a site, the existing structure is rehabilitated and used for a new purpose. </p><p><a href="http://www.chestermangroup.com/koos/index.html">Koo's Corner</a> is a project in Vancouver that took an old automotive repair shop and turned it into six urban loft residences. The existing garage building was turned into two of the lofts, and another four units were built to fit the neighborhood context. Building in an existing neighborhood helps to increase urban density (which makes for more efficient use of existing city services) and makes use of available property rather than buldozing undeveloped land for construction.</p>
