GREEN BUILDING 101: DESIGN INNOVATION

The Green Building 101  series has taken us inside the house and out, looking at site selection , water efficiency , day lighting , eco-power , and environmentally friendly materials . The final segment in our series will cover the last section of LEED for Homes , which is called “Innovative Design.” This somewhat mysterious section seems to be the catch-all area: created to allow new technologies that aren’t currently covered by the rest of LEED-H to earn points. With this in mind, we’d like to showcase some of the most promising innovations in sustainable design – the stuff that might qualify for LEED’s Innovative Design points. We proudly present, in no particular order, Inhabitat’s Top Ten Eco-Innovations…
1.) Living Roofs and Facades
It’s no secret that Inhabitat loves green roofs , green walls , and just about any other building surface  covered in living material . Green surfaces help with insulation, climate control, and retention of storm runoff. Fortunately, it’s easier than you might imagine to inject a little life onto the surfaces of your buildings. Modular systems like Green Grid roofs  and other consumer products can be installed and maintained with little effort or know-how. In doing so, you increase your home’s efficiency and aesthetic value, as well as helping to decrease the urban heat island effect  in your neighborhood from sun radiating off of infrastructural surfaces.
2.) Building Integrated Photovoltaic Technology (BIPV)
In the past, photovoltaic panels were most often added to a building as an exterior afterthought once the construction was finished. But with the development of Building Integrated Photovoltaic Technology (BIPVs), collecting solar energy can become an integral function of a building’s envelope. BIPVs can be used as façade, roofing materials like shingles, and can even be integrated into glass windows! Because they actually form the building’s envelope in addition to generating energy, they reduce material use and all of the environmental impacts associated with transporting and discarding excessive building material, in addition to the whole energy conservation thing. (note: we don’t necessarily back the tract home development scheme pictured above, but we love the image of ubiquitous photovoltaics, even in a suburban sea.)
3.) Light-Emitting Diodes (LEDs)
Don’t let the size of these tiny wonders mislead you; it is their size that provides such incredible versatility. With a typical lifespan of twenty years, LEDs provide illumination  for twice as long as fluorescent bulbs and more than twenty times longer than incandescents. Their light is emitted instantaneously –- unlike the flickering start-up time of fluorescents — and they give off almost no heat compared to their incandescent cousins. Most importantly, LEDs are super efficient, use very little electricity, and can often be run on batteries, which enables portability and use in remote off-grid areas. Among the recent innovations in LED technology we’ve seen recently, our favorites include Philips’ Simplicity  LED light-bulbs and the LED Glass Table , as well as the Portable Light , which was developed for use in developing regions with insufficient infrastructure.
4.) Organic Light-Emitting Diodes (OLEDs)
How does an organic LED differ from a regular one? No, it was not grown in pesticide-free soil. But it does surpass the standard LED for several reasons, including the fact that it requires fewer chemicals and less waste to manufacture than its “conventional” counterpart. But the real reason an OLED has promise for the future is that it’s extremely versatile and flexible — literally. OLEDs come in pliable, layered sheets which conduct and emit light, making them great for screens and display monitors. At larger scale, they could potentially be used on walls and facades to generate light at a fraction of the rate of energy consumption that other types of illumination require.
5.) Rain Collection and Grey Water Systems
Recycling and filtering water  from sinks, showers, and washing machines can provide a typical household with fifty to one hundred (depending on the size of the house and daily use) gallons of water for outdoor irrigation systems and toilet flushing, significantly lowering water consumption. Similarly, rainwater collection systems (depending on the region) can supply a typical household’s entire water needs, including their potable water. Though not necessarily a new idea, rainwater collection design and technology have evolved lightyears recently, as proven by this year’s winner of Metropolis Magazine’s Next Generation 2006 Competition , the Hydro Wall , a concrete and thermoplastic wall system that combines rainwater catchment, storage, filtering and recycling to supply buildings with an efficient and renewable water supply.
6. Electrochromic Windows
Electrochromic windows are a new enough technology that their presto-chango properties still seem like magic. At the flip of a switch, electrochromic windows go from transparent to opaque, permitting privacy on demand while maximizing daylight the rest of the time. In short, the lightswitch transmits voltage across several layers of material that change their properties when the conduction takes place. Because they control the passage of both light and heat into a room, electrochromic windows serve as energy-saving devices in addition to making you seem uber-high tech. Some of the good ones can be found here .
7.) Energy Monitoring Devices
Imagine if as many people counted the watts they consume in a day as count calories. Sometimes we just don’t understand our own consumption patterns until they’re spelled out for us. Thanks to a few clever designers with a mind for making conservation cool, the number of watts your house eats can be easily monitored. UK company DIY Kyoto launched from the idea that where greenhouse gas emissions are concerned, it’s up to each of us as individuals to make a marked reduction. Their Wattson  sits in your house and gives digital readings of energy use, helping make conservation a no-brainer. The Swedish Interactive Institute has also been developing products around this idea with their Design for Increased Energy Awareness  collection, which includes the widely blogged Re:Form Energy Curtain , a drapery that stores and emits solar power in woven photovoltaic textiles.
8.) Sunlight Transport
Most people assume that a room full of daylight can only be achieved where windows and skylights have plenty of sun exposure. Not so with sunlight transport systems. Using fiber optic cables, it’s now possible to make a windowless basement feel like a glass-encased penthouse (though there’s not much cure for the concrete and cobwebs). A number of different companies are pursuing this technology, which not only offers a more pleasant quality of indoor light, but has health benefits for people who must live and work in unlit spaces, and can be paired with solar panels to make it energy-smart and fossil fuel-free. Of the ones we’ve seen, we’ve been most impressed by Parans , Sunlight Direct  and Luceplan .
9.) Structural Insulated Panels (SIPs)
Structural Insulated Panels allow builders to cut down on on-site construction time and reduce construction waste, all while providing an airtight envelope that reduces noise and as an insulation rating superior to generic stick or metal framing. Like creating a life-size livable gingerbread house, SIPS are strong enough for to be a structural wall, but light enough to be used as a roof. A fine example of SIPs put to use due to their simple construction was Sunset Magazine’s 2006 Idea House , which, after opening in the publication’s parking lot for a limited public showing, needed to be completely dismantled and put on a permanent foundation over a basement. SIPs also made an appearance when Sunset partnered with Michelle Kaufmann  on her iconic prefab Glidehouse (above). Piece of cake.
10.) Insulated Daylighting Panels
As we raved about in our posts on lighting and new types of insulation , daylighting is good for everything: it saves energy, it provides a more pleasant quality of light than lamps, it increases productivity and is good for your health. Up until now, however, many people have been reticent to put too many windows or skylights in their house due to concerns over over-heating in the summer, and lack of insulation for keeping warm in the winter. After all, Phillip Johnson’s Glass House  isn’t exactly a paragon of energy efficiency. (And we won’t even get into the privacy issues that come up with too much glass)
Fortunately now, with new technologies like translucent Aerogel insulation , you can use strong, well-insulated, translucent “daylighting” panels to build skylights, walls and entire roofs which will let natural light into your house during the day. Because they are translucent, they have the added value of letting light in while still protecting privacy. There are many companies currently making super-insulated daylighting panels, but the most well-known is probably Kalwall . Check them out here > 
Come back next week for the finale of Green Building 101 !
