Green Options

Psyched to announce thier first offline event, TreeLife by The Cool Hunter, will be unveiled sometime in 2010 (city to be announced). Hey all you tree house builders and fanatics, your time has come for an inspirational modern prefab tree house playground made exclusively for forest loving, fresh air and sky dwelling mavens.

Check out the prefab community blooming online these days! Tiny House Village is trying to connect communities of creative small dwellings. Ideas are abound for these eco communities with Resources For Life’s Small House Society.

Tiny House design has a great set of resources all linked here as well. Check out the plethora of architectural resources,

“Our homes embrace the principles of eco-friendliness and cost-effectiveness, without sacrificing beauty. We can ensure that each dwelling achieves a gold or platinum LEED rating, depending on the particular finishes, building systems, and site design an owner chooses.” ~ Michelle Kaufmann Designs

Each Glidehouse home is solar ready with other renewable energy system options possible such as geothermal, wind generator or hybrid systems. Designed for clean, simple living. The Glidehouse is built in a factory, using the most modern and environmentally friendly building methods and materials.

Some eco features of the Glidehouse include:

• using healthy finishes such as non-toxic paints and formaldehyde-free cabinetry.
• it meets the Energy Star® program standards for energy efficient homes and meets the performance standards of the American Lung Association Health House program.
• it’s insulated with an air-barrier, open cell foam insulation, and all wood-to-wood framing joints are caulked, which makes the home airtight, energy efficient, and less likely to produce mold.
• it uses water-saving plumbing fixtures, on-demand water heaters, and a mechanical ventilation system that is 30% more efficient than typical forced-air systems.
• energy efficient, dual-pane glass windows and doors are placed throughout the home to maximize cross-ventilation and natural lighting, minimizing the need for artificial lighting and climate control.

If you live in dangerous drought conditions, wildfires are a worry.

So imagine a campsite dwelling designed so that you can easily just close it up entirely, completely concealed inside a fireproof sheath, whenever you are away. It is perfect for sites like this isolated area of drought-ridden Australia.

I happened to live in France back in 2002, and during my year there I noticed a pretty significant gap between sustainability as practiced in Europe in the US. In Europe, I was working with large public companies who were already integrating the implications of global warming and sustainbility into their businesses. In the US (and sadly still today), many companies were still arguing whether global warming even existed!

This difference was also evident in houshold products - from luxury hotels in Italy fully outfitted with CFLs to low-flow water fixtures and dual-flush toilets in many homes to small upright washers in even the most basic apartments, the kinds of products associated with our burgeoning US green movement today were already the norm in many parts of Europe back then.

On a recent trip overseas I happened to pick up a French architecture magazine for the flight home. I was pleasantly surprised to see that we had really caught up in the past six years - outside of being written in French, you would have been hard-pressed to distinguish this magazine from any of the leading US architecture magazines.

One article caught my eye, though, for it did point out a slight difference that needs to move across the pond. It was on a beautiful and practical prefab home, called the EvolutiV house by Olgga Architectes of Paris. The house itself is striking, made from two rectangular prefrabicated sections that can be rearranged to develop different floorplans and having exterior walls made from sections of wooden logs. The homes also come with the latest and greatest in eco-design: natural ventilation, rainwater collection, solar panels (both PV and thermal), green roof, radiant heating with an option for geothermal heating/cooling, and the typical eco-friendly materials throughout.

The most interesting piece of the story, though, is that the literature for the house and the articles written about it all refer to the home’s target energy usage: less than 48 kWh / m2 / year, which translates to about 4.4 kWh / ft2 / year. This is 70% less energy usage than the typical US home in similar climates.

It’s not the level of performance that makes this interesting, for many prefab options in the US can do as well. It’s that the media in France AND the architecture firm who designed the house feel compelled to advertise efficiency in terms of a single number that is easy to understand and can be used to compare this home to others one might choose. I’ve rarely if ever seen that in discussion of US prefab options (or other green homes) - outside of a LEED rating, we’re often left to guess exactly how eco-friendly that home is. We’d love to see this become more widespread in the US - information is power, and simple, objective numbers like this can help us separate the truly eco-friendly from innovative designs that are green in name (or advertising) only.

In case you can’t tell, we like green prefab homes. Many are beautiful and innovative, and the best of them really push the boundaries of green practices. But for most of us they’re aspirational rather than practical. Most of us aren’t building green homes from scratch, and even if we are the number of green prefab providers who can deliver cost-effective complete green prefab homes is still quite small.

Which is why we decided to write about small green prefab rooms or homes - “weefabs” - so small that you actually might be able to put one in your backyard. They could serve as a “room-away-from-home” place for the inlaws, a quiet office or TV room out back, or simply a comforting, tranquil place to just hang out and relax. While not affordable compared to pre-made sheds at Home Depot, you can still secure most of these models without having to take out a new mortgage. Which is good, because at least right now most mortages harder to come by than a protest license in Beijing!

We’ve always liked Modern Shed - whether you live in a Mid-Century Modern home or a traditional Cape Cod style in New England, Modern Shed makes a model that will fit in with your design. They have many green features, and you can get several models for less than $10K. Shipping is included in the price, and they’re designed and shipped so that a relatively handy D-I-Y-er can do the install.

If you can’t tell, we’re pretty hooked on the latest and greatest in green prefab design. One big problem, though, is that there’s a huge amount of noise and not all that much action - plenty of fabulous prefab designs and museum / conference exhibits, but very few actual installations (and even fewer mid-market installs, which is where prefab has to go in order to make a true difference in our housing stock).

Finally, the log jam seems to be breaking. Several firms have begun to produce green prefab homes for real people in small but growing numbers. This past month, Marmol Radziner, a prefab company here in Southern California, made a splash with some pretty showy installation videos on local media outlets. These homes are either a) high end or b) for the firm’s founders, so they’re still a ways away from mass-market. But, the videos do a good job of showing what elements make prefab homes unique (factory construction, rapid installation, modular components) and at least to me suggest that they’re not all that far away from being able to replicate these installations on a larger and thus less expensive scale.

Imagine you are Vancouver. Or Beijing. You have this obscure little event called the Olympics to host. There will be a short term high volume burst of people coming. Or you’re hosting a conference that regularly outstrips the available hotel capacity of the city you host it in, producing frustration, high costs, and long commutes for those having to stay out of town.

What do you do? Build more hotels? That’s one solution, but what about the rest of the year, when there is a lower, more typical demand, and you’re left with capacity far exceeding needs, and resources were used to build these hotels that could have been used elsewhere?

Abilmo, a French company, has a possible solution: They make foldable hotel rooms. Come again? Yes, they have been able to fabricate accommodations that can be set up, without a crane, as many as 25 erected in a day. And they’re not shabby, either.

Editor’s note: Modular (or prefabricated) housing is hot, and our friends at Low Impact Living have the lowdown on some of the companies driving this trend. This post was originally published on Thursday, June 12, 2008.

It seems everyone is “going modular” these days with the rapid growth in the movement of green prefab design and construction. The buzz in modular construction is causing a rush of new designs, innovative products, and advanced modular systems being introduced. The goal of prefab is still the same as minimizing waste while maximizing efficiency. To learn more about prefab design and what makes it a compelling form of green building, please click here.

No longer are the days when just calling yourself a prefab company is considered environmentally progressive. Homes are now being made from materials like reused shipping containers, recycled steel, and certified sustainably-harvested wood. The new challenge for prefab companies is balancing the economics of innovative sustainable design with the realities of construction and raw material costs.

We want to highlight some companies doing some very interesting work in the prefab space.

Envision Prefab shows their commitment to the environment by attempting to maintain a zero carbon footprint in both manufacturing and production of their models. Their e-House reuses shipping containers transformed into seamless interior spaces, while including a laundry list of green systems such as tankless water heaters, solar panels, and LED lighting.

In case you missed them the first time around, here are the top 10 international environmental headlines that made news in the blogosphere for the week of March 31 - April 6.

1. Asia — United Nations Climate Change Talks: “Kyoto II” climate talks open in Bangkok

“The first formal talks in the long process of drawing up a replacement for the Kyoto climate change pact opened in Thailand on Monday with appeals to a common human purpose to defeat global warming.

‘The world is waiting for a solution that is long-term and economically viable,’ U.N. Secretary-General Ban Ki Moon said in a video address to the 1,000 delegates from 190 nations gathered in Bangkok.

Prefabrication and Modularity are new eco buzzwords on the menu this year. From homes to furniture, designers are beginning to employ new methods of construction and transportation to cut waste and energy consumption, ensure safety, and achieve greater overall methods of sustainability. When we hear the term “modular prefabricated homes,” we probably think of a little trailer down by the river. This is hardly the case with the
