Building with Awareness is an interesting package loaded with information. It is a DVD with an accompanying book (or a book that comes with a DVD included, depending upon how you look at it). The two nicely complement one another in a fairly unique way. The story contained in the DVD documents the construction of…
The greenness of a building element isn’t always clearly defined. Garbage disposals are one example. Florida Green Building Coalition gives points in their new home plan for not installing one (See Section 2). Others say, in comparison to landfilling your banana peels, a bit of power and water is an efficient way to deal with…
With little fanfare, Kimball Office opened their new San Francisco FiDi showroom with a quiet, green splash. Although they haven’t achieved LEED-CI status yet, they hope to gain gold certification soon. The architectural and design team over at Huntsman Architectural Group created a green space that we noticed as we stepped in. The design team…
The Pacific Northwest has a reputation for being progressive when it comes to green building, with Washington and Oregon setting the pace. But where does Alaska fit into the picture, and how do its green building efforts measure up? With regard to the LEED program, Washington and Oregon each have certified or registered projects numbering…

Radiant heating is a popular option in green buildings. Many green buildings feature it because it is a more efficient, and more comfortable, method of heating. If a building doesn't require air conditioning, it may be possible to eliminate ductwork altogether, or at least use a much smaller system that is sized for air conditioning. And even in buildings where air handling is still necessary, the systems that push the air around can be run less frequently because they are needed only to provide fresh air, and don't need to take care of the heating as well. Radiant heating systems don't cause the air to be dried out in the same manner that heated forced-air systems tend to do. Most of all, radiant heating is comfortable because it is warmest at floor level and slightly cooler at higher levels, matching the human desire for warmth for the feet, and less for the head.
A recent <a href="http://jetsongreen.typepad.com/jetson_green/2007/09/solar-decathlon.html">blog post by Jetson Green about the National Solar Decathalon</a> reminded me of an intriguing product that can be used for in-floor radiant heat systems. Warmboard is a specialty subflooring for use in radiant-heated buildings that doesn't require a concrete slab to embed the radiant tubing. This makes it especially useful for multi-story buildings where a concrete slab floor may be less desirable. Warmboard is much lighter than a corresponding concrete slab, meaning that less structural material is needed to support the floor. It also does not need curing time, unlike a concrete slab, which is another factor that makes it appealing for use with modular and pre-fab construction. <br />
<a href="http://www.warmboard.com/">Warmboard</a> is a plywood material that is slightly thicker than typical subflooring plywood. It has regular channels cut into it that the radiant heating system tubing can be laid into. On top of this, an aluminum plate is formed to the surface, providing a transfer surface to uniformly distribute the heat from the tubing across the floor.</p>
Construction, as many of you know by now, is one of the biggest single sources for waste and may be responsible for as much as 30% of the volume used in some landfills. And, because commercial space is turned over more frequently, the interior build-out of office space is one of the biggest sources of construction debris and waste. As companies change their staff, the space they occupy fluctuates, and often old spaces are torn out and new spaces built with different configurations.
Since the spaces in an office are not part of the structure (in most cases), the walls that divide offices and meeting rooms can be relatively quickly disassembled and rebuilt in a new configuration without affecting the building structure. This flexibility appeals to building owners and tenants alike, because space can be easily customized to meet the particular needs of any tenant. But it leads to an awful lot of waste, as well.
A new system of wall construction devised by Sean Dorsy, a graduate architecture student at The Catholic University of America, uses standard 4 x 8 sheets of plywood cut with slots so that the panel can be unfolded like an accordion to make a wall structure to replace standard stud construction.

Though there are over <a href="http://www.usgbc.org/LEED/Project/CertifiedProjectList.aspx?CMSPageID=244&CategoryID=19&">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 "green" 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.

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.

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," and goes on to declare, "'Green building' is an oxymoron." <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>
<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>
<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>

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>
