They are most typically used for foundation (basement) walls, but can be used in some other applications as well. Of course, they offer green benefits. <br /><br />The most obvious improvement offered by using ICFs is the addition of insulation. Concrete has a very low <a href="http://www.eere.energy.gov/consumer/your_home/insulation_airsealing/index.cfm/mytopic=11340">R-value</a> (an 8" thick concrete basement wall would typically have an R-value of approximately 0.75; even less than a single-glazed window with an average R-value of 1.0). So concrete walls offer very poor thermal performance. Even in the summertime, a concrete basement wall will be cool to the touch, because of this. Adding even a small amount of insulation to the concrete wall makes it better, and ICFs provide a good way of getting an insulated concrete wall

ExxonMobil announced today that they will be pursuing LEED certification for a number of their offshore drilling rigs in the Gulf of Mexico.
"The LEED program already recognizes the importance of having buildings that produce their own energy. Photovoltaic panels are a big hit on those gold and platinum buildings, and at ExxonMobil we're all about the gold and platinum," said company representative Paul Myfinger. "Look at how much energy our rigs produce compared to what they use, it's obvious that they're super efficient!"

In nature, there is no waste. Or, perhaps a bit more accurately, "waste" from any source becomes the feed for another. Everything is a raw material for some other process or system. Sometimes the changes are minor, as with the exchange of oxygen and carbon dioxide in respiration, while at other times they are hugely transformative, such as the use of soil to grow into a structure like a tree.
We're glad to find opportunities to increase efficiency in systems, as a method of waste reduction. Capturing energy is an easy way of improving efficiency and reducing waste. Co-generation systems get double use by generating both electricity and heat, the heat being a waste product of the electrical generation system.
A wide range of companies are pushing to reduce their waste, and "zero waste" is a concept that is being discussed in more and more boardrooms. A recent article in the Boston Globe discusses how this idea is spreading.

The third Wednesday of the month is the regular meeting time for Green Drinks in southeast Michigan at Leopold Bros. in Ann Arbor. This was actually the second Green Drinks of the month, because a special Green Drinks Pub Crawl was organized in conjunction with the Remodel Green Conference last Friday.
The Michigan Green Drinks combines with the o2 Network because the membership of the two groups has so much overlap. This month's Green Drinks had about 15 people atttending over the course of the evening. There is not a set program for the evening. Rather, it is just an opportunity to meet like-minded people.
Discussions (that I was part of or was able to overhear) included industrial ergonomics, supply chains and materials for the auto industry (there have been a number of current and former designers from the auto industry who have attended these events), and a like-minded local group called Junto that is modeled on an intellectual discussion group founded by Benjamin Franklin.

Image credit: City of MelbourneThe 10 story Council House 2 (CH2) building in Melbourne is very likely Australia's Greenest Building. It is the first building in the country to receive six stars in the Green Building Council of Australia rating system.
The building is wrapped with photocell-controlled louvers made of recycled wood which help to temper the interior environment by controlling solar gain. Prominent shower towers are used as part of the cooling system for the building, and a set of large wind turbines on top of the building help to exhaust stale air out of the building. In addition to the visually striking aspects of the building, it also contains a host of features inside that contribute to the building serving as an exemplar of sustainable design.
The building is 12,500 square meters (134,500 square feet) and serves as an office building for 540 City of Melbourne staff, plus ground floor retail space. However, the underground parking includes only 20 parking spaces, but 80 bike spaces are provided (and 9 showers for cyclists are also part of the building's amenitites).

<p><img src="/files/images/x.gif" width="272" height="189" alt="The BioDaversity Code" />This past Friday, I attended the <a href="http://remodelgreen.org">Remodel Green</a> Expo and Conference in Plymouth, Michigan. This was a one-day conference largely coordinated through the local chapter of the National Association of the Remodeling Industry (NARI). There were two rooms of exhibits by manufacturers and suppliers for products ranging from architectural salvage and materials, to home power generation systems, to lighting and plumbing manufacturers, all emphasizing green solutions for building and remodeling. <br /><br />The keynote address was by David Johnston, a former remodeling contractor, who is now a consultant and author (<a href="http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2FGreen-Remodeling-Changing-World-Room%2Fdp%2F0865714983%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1174317245%26sr%3D8-2&tag=greeopti-20&linkCode=ur2&camp=1789&creative=9325">Green Remodeling : Changing the World One Room at a Time</a><img src="http://www.assoc-amazon.com/e/ir?t=greeopti-20&l=ur2&o=1" border="0" width="1" height="1" /> and <a href="http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2FBuilding-Green-Black-White-World%2Fdp%2F0867185074%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1174317593%26sr%3D8-1&tag=greeopti-20&linkCode=ur2&camp=1789&creative=9325">Building Green in a Black and White World</a><img src="http://www.assoc-amazon.com/e/ir?t=greeopti-20&l=ur2&o=1" border="0" width="1" height="1" />)who spoke about climate issues and about why building greener buildings matters. Johnston prefers the term "Global Climate Change" to "Global Warming" because the effects will be more complex and catastrophic than mere warming. "Global Warming" will actually make for a colder Europe, with the Gulf Stream diverted further south by a gradually warming polar cap. In addition to talking about why greener buildings are important, he also spoke extensively about how to make better, greener buildings. </p><p></p>

<p><img src="/files/images/veg.jpg" border="0" width="240" height="160" />Does a building need to be LEED certified in order to be green? Can produce be good even if it isn't labeled organic? I've come across a couple articles recently that ask some questions about the labels people use to try to promote their products, and the value those terms offer. </p><p>There are costs (sometimes very high costs) for participating in these programs. These costs can be prohibitive for small-scale businesses, which, ironically, are often the ones most interested in pursuing a greener way in order to distinguish themselves from their larger competitors.<br /><br />'Organic' has become a regulated term. In 2002, the USDA set guidelines for using the term. A farm earning more than $5,000 per year is required to complete extensive paperwork and pay certification fees if they want to advertise their produce as being 'Certified Organic.' And there are questions about the value of the term 'Organic" anymore.</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>

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

Although they have been well established in central Europe for decades, it is only relatively recently that the idea of a vegetated roof has been considered in North America.<br /><br />Contemporary vegetated roofs have little in common with old "earth sheltered" buildings of the 70s. A vegetated roof is an integrated system, with everything engineered for its performance in the system from the roof membranes which keep water from entering the building to the "growth media" engineered soil that sustains the plants.</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>

Photo Credit: Bonded LogicThere are many, many different options available for insulating a building. Whether for new construction or for an addition, there are many manufacturers and different products which all are meant to accomplish essentially the same thing: controlling the temperature inside the building. Without getting into alternate construction methods, consider some options for insulation in standard frame construction.
Insulation is generally material inserted in the spaces between framing (wall studs). It's purpose is to slow down the process of heat transfer. Creating a lot of little airspaces between the fibers of the insulating material, and using a material that is, itself, a poor conductor of heat makes a wall that retains heat, rather than allowing it to be lost to the outside.

Heating your house with firewood is completely retro. I mean, cutting up trees and burning them, that's just so old fashioned and inefficient, and not green at all.
What do you mean, wood burning can be green?
In fact, masonry heaters (which are also sometimes called "Finnish heaters" or "Russian heaters") can be a green source for heating a home. While a traditional fireplace may be only 10% efficient (which is to say not!), a masonry heater can be 90% efficient. A well insulated house (even in a cold, Canadian location) can be heated on a single cord of wood per season. In a sense, a masonry heater is to a traditional fireplace what a compact fluorescent (or, even better, and LED light) is to an incandescent bulb.

Do you feel like no one else in your community is interested in a greener lifestyle? Are you interested in meeting other like-minded, green-oriented people in your area? There are opportunities to make new connections and meet others in your community who are similarly inclined towards green living.
Green Drinks is an international program for people from NGOs, academia, government and business. "These events are very simple and unstructured, but many people have found employment, made friends, developed new ideas, done deals and had moments of serendipity. It's a force for the good and we'd like to help it spread to other cities."

Icicles on the eaves and snow on the roof are more than just an ornament of wintertime. They can also be instructive signs that you can use to get a sense of the way your house is using energy and a way to tell whether or not there are problems that you should address to improve your energy efficiency and perhaps even to preserve your roof structure.
With the recent snow that much of the midwest and northeast US has had in the past week, now can be a good time to take a look at your roof to see how well your house is doing in terms of energy performance. An article from Home Energy Magazine gives a good set of guidelines about reading the snow on your roof to see how well your attic insulation is working
