Foster’s Solar-Skinned Buildings Signal Market Tripling: Energy

Volvo Invents a Solar Panel That Unfurls From the Car Trunk

BASF SE (BAS) also is developing products for the market. The Santa Clara football stadium near San Francisco will have three solar-array covered bridges, with a solar canopy built over a roof terrace, generating their own power. Tipping Point Were approaching a tipping point and at some point in the future building integrated solar would be a must-have in the design of any new and significant building, said Mike Russell, managing director of Accentures utilities group in London. Solar technology has been installed onto the roof of the Pituacu Stadium in Brazil, as well as its locker room and parking canopies, as the nation prepares for the World Cup. Viaticus has invested in Dyesol Ltd. (DYE), which makes dyes that mimic how plant leaves turn sunlight into energy.

But trees aren’t the only way to keep a building cooler. Solar panels, when mounted on a roof, also provide valuable shade on top of generating clean electricity. Researchers at the University of California San Diego decided to have a closer look at the panels’ cooling effect to see how big it is and what kind of panel orientation provides the biggest benefits: “Using thermal imaging, researchers determined that during the day, a buildings ceiling was 5 degrees Fahrenheit cooler under solar panels than under an exposed roof.” UCSD the amount saved on cooling the building amounted to getting a 5 percent discount on the solar panels price, over the panels lifetime. Or to put it another way, savings in cooling costs amounted to selling 5 percent more solar energy to the grid than the panels are actually producing for the building researchers studied. […] Rather than the sun beating down onto the roof, which causes heat to be pushed through the roof and inside the ceiling of the building, photovoltaic panels take the solar beating. Then much of the heat is removed by wind blowing between the panels and the roof. The benefits are greater if there is an open gap where air can circulate between the building and the solar panel, so tilted panels provide more cooling. Also, the more efficient the solar panels, the bigger the cooling effect, said Kleissl. For the building researchers analyzed, the panels reduced the amount of heat reaching the roof by about 38 percent. ( source ) Of course, solar panels aren’t as effective as reflective roof membranes/paints/materials , but nothing prevents people from combining the two technologies, and it’s good to know that solar panels provide this side benefit that has been rather overlooked so far.

Solar-Powered Cars Hit The Racetrack

Last year, a solar-powered boat sailed all the way around the globe for the first time. A few weeks ago, a solar-powered plane completed a trip across the country. ROGER DUNCAN: We’re really not looking at solar as a mass transit option. HENRY: Roger Duncan is a research associate at the University of Texas at Austin. He says right now, solar-powered cars, planes and boats are really only good for transporting a single passenger. That’s because the bigger the vehicle, the heavier. It’s difficult to move heavy weights using solar energy directly. DUNCAN: However, we need to understand that solar power occurs in many different forms. In fact, the electric vehicles that are starting to be purchased around the county – and I own a plug-in hybrid vehicle – can indeed be powered by solar. HENRY: He sees a future where there are solar panels everywhere – but they’re feeding power into the electric grid, and then into lots of cars.

Forget solar panels, here come building-integrated photovoltaics

Bloomberg reports on the rapid growth in building-integrated photovoltaics, or BIPV. These are solar powerharvesting cells that are incorporated into the walls, roofs, and windows of buildings integrated seamlessly instead of being bolted onto a finished building as an apparent afterthought: From stadiums in Brazil to a bank headquarters in Britain, architects led by Norman Foster are integrating solar cells into the skin of buildings, helping the market for the technology triple within two years. The market for solar laid onto buildings and into building materials is expected to grow to $7.5 billion by 2015 from about $2.1 billion, according to Accenture Plc, citing research from NanoMarkets. Sales of solar glass are expected to reach as much as $4.2 billion by 2015, with walls integrating solar cells at $830 million. About $1.5 billion is expected to be generated from solar tiles and shingles. The technology provides a respite for solar manufacturers, opening the way for them to charge a premium for products. Traditional solar panel prices have fallen 90 percent since 2008 due to oversupply, cutting margins and pushing more than 30 companies including Q-Cells SE and a unit of Suntech Power Holdings Co. into bankruptcy. The industry is already well established in the U.S., where Dow Chemical Co. (DOW), the countrys largest chemical maker by sales, is selling in more than a dozen states solar shingles that look like regular roofing material.

Bonus: Solar panels help keep buildings cool, reducing A/C needs

Volvo is famous for favoring safety over style, making the selection of Synthesis Design + Architecture, best known for its sweeping, sci-fi inspired solutions, a bit of a surprise. The solar-powered pavilion is a stunning showcase for its new hybrid electric V60 model, and the parabolic platform is intended to highlight the sedate sedans impressive technological innovations at marketing events while charging it up for the ride to the next city. Algorithms efficiently configure the materials into visually striking structures. Unlike many green design projects that tack on aesthetics like an aftermarket body kit, Synthesis was driven by them. Synthesis principal and USC professor Alvin Huang has been a long time researcher of dynamic mesh relaxationa design approach pioneered by Frei Otto and amplified by computer science that is focused on the physical properties of dynamic materials and efficiently configuring them into complex, visually striking structures. The design process involved digital and analog techniquesdigital tools allowed for quick explorations of designs while physical models acted as proof of concepts for the carbon fiber frame, mesh surface, and artfully placed solar panels. The combination of the two styles of design equipped the team with an intuitive sense for what works to develop an attractive form that could stand up to the rigors of use in the field. The iterative exchange between the parallel digital and analog models allowed us to further refine design technique, and perhaps more importantly, design intuition, in terms of achieving desired effects. says Huang. While the aesthetics are fresh, the design principles were pioneered by German architect Frei Otto back in the 1960s and 70s.

UC San Diego Demonstrates How Solar Panels Help Beat the Heat

solar panel cooling powell roof thermal and photo

In a study in an upcoming issue of the journal Solar Energy, Kleissl and his team published what they believe are the first peer-reviewed measurements of the cooling benefits provided by solar photovoltaic panels. Using thermal imaging, researchers determined that during the day, a buildingas ceiling was 5 degrees Fahrenheit cooler under solar panels than under an exposed roof. At night, the panels help hold heat in, reducing heating costs in the winter. aTalk about positive side-effects,a said Kleissl. As solar panels sprout on an increasing number of residential and commercial roofs, it becomes more important to consider their impact on buildingsa total energy costs, Kleissl said. His team determined that the amount saved on cooling the building amounted to getting a 5 percent discount on the solar panelsa price, over the panelsa lifetime. Or to put it another way, savings in cooling costs amounted to selling 5 percent more solar energy to the grid than the panels are actually producinga for the building researchers studied. Of course, the report concedes, solar panels arent the single most effective way of reducing the impact of the sun on your power bill.
