Germany Wins Solar Decathlon

For the past week, 20 teams took over the National Mall with their best attempts at a net-zero, solar-powered home, all with hopes to discount viagra pharmacy win this year's Solar Decathlon.  Today, after competing in ten different contests, the winners were crowned, and for the second time, Germany took first place.

The cube-shaped surPLUShome, covered on all sides by dark metallic solar panels, produces more than twice the propecia uk cost energy it uses.  The roof is covered with single-crystal silicon panels and just try! cheap discount levitra the sides with thin-film copper indium gallium selenide (CIGS) panels.  The entire system has a capacity of 11.1 kW.

Just as impressive was the efficiency of the home.  The team got a perfect score in the Net Metering contest.  Features like one large multi-purpose room with different "zones" instead of separated rooms, vacuum insulation structural panels, a boiler/heat pump system for hot water and heat and louver-covered windows created an energy-sipping home.

Two U.S. teams also placed in the competition:  Team Illinois took second and Team California took third.  All of the entries showcased innovative and beautiful designs.  Check out virtual tours of all the entries here and let the inspiration begin.

New York Requiring New Government Buildings to Go Green

Governor Paterson of New York has been using his political power for good recently.  In May, he ordered all state agencies to switch from bottled to getting cialis tap water and yesterday he signed the free viagra sample State Green Building Construction Act which requires all new construction and renovations of government buildings to meet green guidelines.

The state's Office of General Services (OGS) will be in charge of the new building standards.  While the guidelines haven't been written yet, they will probably borrow heavily from LEED certification requirements.  The OGS has 31 LEED-accredited designers and buy low price levitra every new construction project overseen by the agency is assigned a LEED professional to identify sustainable building opportunities.

New Building Energy Label More Aggressive than Energy Star

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has come up with a new energy labeling system for buildings that will be more in-depth and more aggressive than the Energy Star labels for buildings.  The new system called the Building Energy Quotient will be unveiled this fall and will assign grades like a report card to all types of buildings except residential ones.

The Building EQ will consist of cialis and diarrhea two different ratings based on energy use per square foot per year.  One will factor in the building's design while the other will rate its energy saving performance.  Both areas will be graded on a scale of A+ to F, with A+ meaning a building accomplishes net zero energy (it produces the same amount of energy it consumes) while an F will go to it's cool cheap viagra soft those buildings considered unsatisfactory.

While there is definite overlap between this rating system and Energy Star, Building EQ goes beyond the former's pass/fail labels and makes the best grades tougher to come by.  An Energy Star building would receive a grade of B on the Building EQ scale, while a typical commercial building would get a C.  The new program is buy levitra online without prescription not as encompassing as LEED though, which takes into account water use and overall environmental impact of a building, not just energy use.

As we get closer to mandatory labels for buildings, developers will now have three voluntary rating systems to choose from, hopefully placing a premium on those buildings that achieve the highest ratings and cheap discount tramadol making energy efficient buildings the norm and inefficient ones a thing of the past.

Habitat for Humanity Building 5,000 Energy Efficient Homes

Habitat for Humanity International and The Home Depot Foundation are teaming up to build 5,000 energy efficient homes over the next five years proving that energy efficiency is attainable and necessary for everyone.  The $30 million Partners in Sustainable Building program will issue grants to Habitat affiliates for homes built following Energy Star, LEED or other nationally recognized green building guidelines.

In 2009 and 2010, 1,500 sustainable homes will be built by 120 Habitat affiliates in 45 states.  The program will grant $3,000 per home built to Energy Star standards and $5,000 per home built to a higher standard, like LEED.

Features like efficient water heaters, programmable thermostats, low-flow toilets and shower heads, weather stripping and better insulation are making a huge difference in the homes' energy use.  In a pilot program last year where 260 homes were built, the sustainable features led to energy savings of 15 to 30 percent.  For those that were built to LEED Platinum standards, energy savings have hit 50 percent.

The partnership is also granting money to establish training programs for greener building practices for 440 affiliates.

Dubai Syscraper to Integrate a Solar Thermal Tower

Putting solar panels on the roof (or side) of your skyscraper is so 2008. If you really want some efficiency without all those complicated photovoltaics. If you really love renewable energy, and you also like EXTREME temperatures, you should just buckle down and buy buy viagra without prescription put a solar power tower at the top of buy cialis on line your skyscraper.

And that's the idea of the Almeisan Tower that's been designed for Za'abeel park in Dubai.

The tower would be a home to an observation deck, a cafe, a children's library and community meeting space, and would produce enough electricity to power itself, and several neighboring buildings. The solar power portion, at the top, would simply be a bunch of rotating mirrors that focus the sun's light on a point at the peak of the structure. That point would get so hot that water pumped through would vaporize, and turn a steam turbine to create electricity. It's not a new idea, eSolar is building several of these plants in America now, and Abengoa's solar thermal towers have been producing power in Spain for years.


But I've never seen anyone planning on sticking one on top of a building.

Solar thermal power is generally more well suited to centralized power generation, where lots of energy can be produced off-site on cheap land in sunny areas. But I'm not going to buy levitra on the internet fault the only for you buy low price cialis building's designer, Robert Ferry, for thinking outside the box. I hope this thing gets built, if only because it's kinda awesome.
