As an owner/builder, I’m always on the lookout for new products that make a difference in how we build or use materials. Walking the tradeshow floor at Globe 2010, I found four products that caught my eye as we look toward the future of the built environment.

USA – Dow Chemical Company- The Dow™ POWERHOUSE™ Solar Shingle is the company’s latest innovation showcased at GLOBE 2010. A recent recipient of GLOBE 2010’s Foundation award for “Environmental Excellence in Emerging Technology,” their solar shingles not only protect a roof from the elements, but serve up a photovoltaic charge at the same time. The unique product design has similar weight, reveal and installation practices as an asphalt shingle while also generating electricity. DOW’s Solar Solutions (DSS) technology uses a cost-effective and durable PV material called CIGS (Copper Indium Gallium diSelenide). The electrical circuitry is integrated into every shingle and is connected by wireless plug-style connectors. Dow also recently announced in February, its plans to build the first full-scale production facility for its solar shingle facility in Midland, Michigan, bringing with it more than 1,200 jobs to the marketplace. Could it be affordable, renewable energy roofing solutions are on the horizon?

Canada – MagWall Pacific Inc. Tucked into a small booth on the tradeshow floor is a new SIPS (Structural Insulated Panel System) building product that has some very cool new features. SIPS built homes are generally much more efficient than stick-built homes. Think of SIPS like an extremely efficient Oreo cookie. A hard crust on the outside, (generally OSB plywood) with a fluffy foam filling in the middle. On the MagWall systems, the OSB is replaced with sheathing boards that have a magnesium oxide base making it fire and insect resistant and impervious to mold, because there is no wood product in it. Additionally the ability to erect structures in wet or cold conditions is not a problem, so costly delays in schedules are minimized. As a bonus, it can also eliminate the use of costly additional products used in construction. For example, interior and exterior walls can be finished without additional sheathing, and the company claims vapor barriers are not necessary. Currently the company’s focus is on providing healthy, affordable, sustainable and energy efficient buildings, that require less dependence on highly skilled labor. The company is currently in talks with multiple countries, and even UN and Disaster relief efforts. After just completing the envelope of my own SIPS house, it wasn’t hard to see how these MagWalls would have made a huge difference in shaping the course of our project. www.mag-wall.com

MicroHeat’s 9kW electrical instantaneous hot water system. Photo by Robert J. Pennington

Australia – MicroHeat® Technologies PTY LTD. Tankless hot water heaters are nothing new to the market. But behind this little white box is a whole house hot water heater with a 98% efficiency rating saving both water and greenhouse gas emissions. Normal tankless hot water heaters rely on the flow of water to run through heated coils to deliver hot water to a faucet or shower system. This can mean running and wasting water longer than necessary until it is at the right temperature to use. MicroHeat’s electrical instantaneous hot water system eliminates that heating coil element altogether and instead uses water as the conductor. The water is energized (or heated) via inert electrodes in the water stream. The result is instant hot water, but water is not the only resource being saved. Instead of a constant flow of electricity running to heat big tanks of water, this smart system turns on when you need it and can be placed in convenient locations closer to the source of use. The system on display was a 9kW single-phase unit. The best part is, it senses when it needs to add more juice to the system and delivers absolute temperature control. You can increase the flow but retain the temperature. Still in the research and development phase, MicroHeat has already received grants from the Australian Government and support from the Victorian Centre for Advanced Materials Manufacturing. But this little heater is keeping cool about its technology. Currently no website or marketing efforts are available to the public. We’ll just have to wait.

Sherpa aluminum timber connectors. Photo by Jen Pennington

Austria- Sherpa®- Good things come in small packages, and this little mounting and assembly hardware introduces a new technique for traditional timber construction. Available in a variety of shapes and sizes, the product provides a simple, safe and reliable connector between load bearing trusses, joints or any other timber connection. Two aluminum-molded plates contain a male and female piece that slips into each other to form a very strong connection. A concealed fastener and a good alternative to Simpson® Strong ties and a semi-concealed fastener allows the beauty of the hardware to become a part of the design. What makes the product sustainable is in the fact that a structure can be just as easily disassembled without wasting valuable wood resources. Beams are lifted and joints can be non-destructively disconnected.

On a recent tour of the largest living green roof in North America atop the Vancouver, B.C. Convention Centre, one can’t help but be awed. The tour organized by Dow Chemical Company as part of Globe 2010 was a rare glimpse into the dichotomy of what you see vs. what you can’t see. Designed by LMN Architects, the building is the world’s first LEED Platinum convention center. It’s about taking in something visually and understanding at a deeper level that natural beauty and the creation of new wildlife habitats in urban settings can successfully coexist with the right mix of landscape architecture, engineering, and construction. The fact that one can easily take for granted the man-made materials underneath an organic surface is a testament to its success.

Brilliantly colored sedums looking towards the water

As you step out the doors onto the first level, one is struck by the brilliant red, orange and pink beauty of native sedums blooming in spring amidst a precisely placed irrigation system. Bruce Hemstock, Landscape Architect for PWL Partnership explains that the irrigation system utilizes black water from the convention center and desalination machinery to water the plants making it a very sustainable system. The vast expanse of this orderly growth is amazing and you can’t even see the grasses above yet. Walking along the sloped path that leads to the green areas of the main roofs, one passes by the apiary of bees that help pollinate the area. As you step up to the grassy rise of the roof you are instantly transported to a park in the sky. It is so large at six acres that you never feel as if you are on an actual roof, and therein is the real beauty of it. Now in its second year of growth, the illusion is so surreal in an urban environment that it’s easy to disregard what lies beneath the top layer.

Roof layers and substrate display at Dow's both at Globe 2010.

Digging down into what makes the roof so unique is the fact that the layers that go into a normal roofing system are inverted. As Mike Kontranowski, the Strategic Market Director, Architectural Markets for Dow Building Solutions explains, “It’s turning the roof upside down.” In this case, 2.5 million board feet of Styrofoam™ brand insulation and more than 500,000 board feet of Styrofoam™ Highload insulation from Dow sits directly on top of the roof. On top of that lies a series of other substrates, and protective barriers before the placement of soil and the thousands of indigenous plants and that grow there. With the addition of all these materials, the lightest weight component, keeping the roof thermally stable, reducing weight load,  and enhancing energy efficiency at the base is the Styrofoam™. A dimpled water barrier on top of that prevents water from seeping through and also holds droplets of water to retain moisture in the soil.

The roof is truly inspiring with its many levels of beauty and sustainable attributes. As green roofs become more popular in cities, my hope is that those in the design, building and materials industries share this knowledge readily. Not just amongst the largest architecture firms and contractors but down to the small business levels of builders and designers in outlying areas or smaller cities where adoption is slower to manifest. If we are truly concerned about creating eco communities and championing environmental and energy efficiency benefits, the challenge for all is how to inspire change broadly while making it affordable to install in the first place.

Rick Woodbury in his Tango at the X Prize showcase

Today at the Specialty Equipment Manufacturing Association (SEMA) 2009 show in Las Vegas, in the midst of some very sweet cars, parts and accessories, it’s easy to get sucked into the shiny beauty of gorgeous machines. An unveil by color master/designer Chip Foose and builder Peter Klutt on their Super Cuda collaboration was stunning. The guys from Galpin Auto Sports (GAS) and Ford rebuilding a 69′ Mustang live for the MTV crowd had all the right glam. But what was really disappointing was the fact that SEMA’s “Making Green Cool Zone” might have referred to the Siberian-like space it occupied at the back of the South Hall in the Las Vegas Convention Center. This was a shame because this area was the most exciting in terms of design, innovative engineering, and new eco-friendly automotive products.

X PRIZE from Progressive Insurance Automotive was the key sponsor for the area and a selection of cars from competing teams adorned the area. The X PRIZE awards 10 million dollars in prizes to the teams that win a multi-stage competition for clean, production-capable vehicles that exceed 100 miles per gallon energy equivalent (MPGe).

HP2g

The vehicles on display showcased the depth of imagination and bold design. Sleek modern looks paired with the most practical of concerns for a lower carbon footprint, safety, performance, and affordability, were all key factors in the development of these new vehicles.

Just around the corner from the X PRIZE teams were folks like Doug Pelmear of HP2g. His uniquely engineered 1987 Ford Mustang hybrid delivers about 110 MPG running on E85 (85% Ethanol). He and his team made a more fuel-efficient engine using variable displacement to transition the car from running on eight cylinders down to firing on just one. He also proudly mentioned that he drove from Ohio to Vegas, only stopping once in Oklahoma for gas.

Azhar Hussain on the new Mavizen TTX02 electric racing superbike

Also unveiled today was the world’s first electric superbike, the Mavizen TTX02. This electric racing motorcycle uses an Open Source OS and is nicknamed the “laptop on wheels.” It’s also very lightweight and tight. When speaking of the role that innovative racing technologies play in bringing products to market, Azhar Hussain, founder of TTXGP (the world’s first zero carbon, zero emission motorcycle race), said today, “…competition first it’s R&D on steroids.”

With all the great new ideas being set forth, it was unfortunate that the press conference background for some of these innovators was some leftover green cloth with an 18 x 24 inch sign with a tiny Making Green Cool logo on it. In one area all the other exhibitor cars were so closely put together, it was tough to maneuver around them. You just felt bad for these guys. Like they were put in a corner and told not to make a fuss.

Okay so maybe you don’t need big fancy graphics, but when some of the most innovative work in the automobile industry is not showcased with the enthusiasm it deserves, how are we ever going to expect people to get excited and on board with greener, smarter alternatives?

I can’t help but remark on a concept Philips is promoting for an outdoor lighting structure that transforms from a solar flower during the day to a wind turbine on cloudy days to a nightlight. It’s been out for a few months, but as a designer, I’m drawn to both it’s functional and aesthetic qualities. The concept is called Light Blossom. And I definitely want to see this concept bloom.

The idea is to provide a large tower that collects solar energy on the inside of its open petals, moving in harmony with the position of the sun. On cloudy or windy days, the petals half-close upward to catch the wind and convert the movement to energy. At night the petals close to form an LED nightlight providing only the light that’s necessary. Great for cities, but even better for rural areas where a power infrastructure is not possible, or power outages are frequent. A smaller version for residential use I believe would find a very willing market.

What I truly admire about the concept is that it takes an everyday mainstream item like a streetlight and serves up sustainability with style. Truly remarkable is how simple a concept it is in theory and how in line it is with the Philips brand of sense and simplicity. With so many variables, it surely won’t be easy to build nor maintain. Harder still will be making it cost efficient enough for cities and communities to afford. But if Philips can make it a reasonably priced option to retrofit or build into new communities, that’s not good design–that’s great design. Just think of it…wild energy flowers scattered from the seeds of imagination.
