Adaptive re-use plus brownfield reclamation are key factors in land conservation and reducing unnecessary sprawl. These are good for the economy, communities, and the environment. More plans need to be implemented and the importance stressed that this is our one chance to re-do and un-do our environmental impact so that future generations can make their choices.
The Atherton House in Atherton, California is an ideal example of how to incorporate manmade elements that pre-exist on a site to benefit that site.
A family in Atlanta gave up half their house and half the things they owned to support The Hunger Project. Actions like these beg the question, “Could I give up half of my house?”
A family in Australia has created their own tiny wetland as a part of a household grey water system. It is a fairly large DIY project, but, as the article demonstrates, not an overwhelming project. The writer even enlisted his young children to help in the construction. Black water is toilet waste and other water…
Editor’s note: Just like our friends at Low Impact Living, we’ve got passion for saving water… so we were very happy to see this post about a new technology for homeowners interested in doing just that!

As I mentioned in my KBIS Report, I was struck by the sizes of bathtubs on display at this year’s kitchen and bath trade show. Though green was king thoughout most of the convention, companies that pitch themselves as catering to a luxury market seem to be sending the message that if you have enough…
It is time to start thinking about getting our homes ready for winter. Maintenance and repair work done while the weather is still mild will pay off not just in the coming cold weather, but with year round benefits. Here are five common issues to think about when considering your winterization projects, and how to avoid making some common mistakes while improving your house.
Window film insulates windows. False.
A window film serves as a draft barrier to stop air leaks, rather than effective insulation. The plastic film itself will contribute very little. Having another air layer is more helpful, and keeping moisture sealed out can help reduce frost forming on old windows. But if you have big windows that are losing lots of heat, a quilted curtain can be more helpful. Windows are big thermal holes in your walls, and even very efficient windows lose heat much faster than the walls that support them. A window film adds only a slight increase, but it can be effective for stopping drafts.
Last week, I attended a driving event at the GM Proving Ground in Milford MI. Driving through the campus, there were several places where roads converged at roundabouts (sometimes also known as rotaries) rather than intersections with stop signs. (I’ll have more to say about the content of that event later.) But even before I arrived, I had gone through a couple more roundabouts on the roads in Milford, MI, where GM’s Proving Ground is located. That started me thinking about roundabouts, and how they are greener than standard intersections.
A modern roundabout … is a circle “designed for very low traffic speeds, about 15 mph.” Entrances and exits are curved so that motorists must travel slowly — far different from the rotaries of decades ago, which typically allowed drivers to enter at 35 mph or faster. The Institute says a modern roundabout typically needs to be about 100 feet across so that it can be properly designed to slow the entering traffic. (New Urban News)
Because the traffic only needs to slow down rather than stopping, all the cars traveling through a roundabout avoid the stop-and-go of a stop sign or a red light. Collectively, this adds up to thousands of gallons of fuel saved for each intersection. Avoiding a full stop also allows each driver to get through the intersection faster, which helps make overall travel times shorter.

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>

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.
