Wind-powered Parking Garage

First Wind-Powered Parking Garage Opens In Chicago

August 31, 2010
By: Crisp Green




“Windy City” lives up to its name as Chicago’s newest parking garage becomes the first to generate it’s own energy with spinning vertical wind turbines.

You might generally associate parking garages with the stark cement-colored monotony that most people despise about urban life. Thanks to a new design by the architects of HOK however, parking garages are being viewed in a whole new green light.

Dubbed the 'Greenway Self Park', this eco-friendly parking garage offers far more than just a column of dizzying vertical turbines up it’s outer wall. The structures array of sustainable practices also includes:


* Local and sustainable building materials

* A green roof and rainwater cisterns for irrigation

* High-efficiency glass

* Recycling programs

* Energy-efficient lighting

* Programs to encourage the use of energy efficient vehicles

* Electric car charging stations

* Air quality initiatives

* Tips for Greener Living in the lobbies

* Zipcar and I-Go car sharing vehicles


For the sake of public education, a “way-finding system” has also been incorporated at each elevator lobby to educate users on how to live more sustainably and protect the environment. A reversible meter has also been included to measure the amount of energy generated by the turbines and and piped back into the grid of the city each year. HOK is currently pursing LEED certification for the building.

Top 10 Energy Efficient States

Best States for Energy Efficiency

Sept. 3, 2010
By: Elisa Wood

If you live in Connecticut, California, Maryland, Massachusetts, Pennsylvania, New York, Texas, North Carolina, New Jersey or Ohio your state is doing something right – a lot right – when it comes to energy efficiency.

The ten states deserve kudos, in that order, for policies that encourage energy efficiency, according to a report issued this week by the Center for American Progress and Energy Resource Management Corp.

If other states achieve similar market dynamics, the US construction industry may pull out of its current slump, says the report, “Efficiency Works: Creating Good Jobs and New Markets through Energy Efficiency.”

The US could add 625,000 full-time sustained jobs over the next decade if it retrofits 40 percent of the nation’s homes and commercial buildings, according to the report. Such an effort would bring $500 billion in new investments to upgrade 50 million homes and office buildings and generate as much as $64 billion a year in cost savings for U.S. electric ratepayers.

Why is this especially important now? Because the economic downturn cost more than one in three construction workers their jobs, leaving unemployment in the industry “at Depression-era levels,” the report said.

“To confront this crisis, the U.S. jobs market needs sustained new demand for the skills of construction workers that is grounded in providing real value to the economy through enhanced productivity, greater efficiency, and improved asset value for real estate,” said the report. “Such a solution is readily available. Our country needs a national program to retrofit America’s homes, offices, and factories for energy efficiency—a program that can provide an important answer to the jobs crisis facing our country.”

As is often the case with US energy policy, it is states, not the federal government, leading the way in fostering energy efficiency markets. The report identifies ten strategies employed by top states. They are:


•Energy efficiency measures in Renewable Portfolio Standards—policies that not only require utility companies to meet a set portion of demand from renewable energy but also include energy efficiency as a qualifying form of clean energy.


•Energy efficiency measures in Renewable Energy Credits—policies that establish markets for tradable clean energy credits and include energy efficiency as a qualifying clean energy resource.


•Energy efficiency specific standards that require utilities to plan for meeting a percentage of future growth in demand through energy efficiency instead of increasing supply. These policy tools include Energy Efficiency Resource Standards and Energy Efficiency Portfolio Standards.


•Unbundled utility structures in which energy transmission and distribution utilities are separate from power generation companies that own power plants, encouraging least costs strategies for meeting energy demand through conservation.


•Decoupled utility rate structures, where utilities’ rates are adjusted to compensate for changes in the volume of energy sold, removing the structural disincentive to conserve energy.


•Aligning efficiency with utility companies’ shareholder benefits, such as bonus rates of return, reimbursing program costs, or other incentives that help transform efficiency from a special program into a core business practice.


•Penalties for noncompliance with energy efficiency standards, to ensure that well-intentioned programs are effectively implemented, monitored, and improved upon over time. Effective policies must have real consequences.


•Regulatory cost-benefit tests that focus on utilities’ real costs, in order to isolate the specific value offered by energy efficiency investments.


•Property-assessed financing structures that link the benefits of installed efficiency to a building, rather than the owner of the building, allowing repayment of financed investments to transfer automatically to new owners.


•Service assessment delivery structures, which allow government jurisdictions to directly facilitate financing of upfront capital costs, assuring repayment through municipal or other service assessment mechanisms.


The top states do not use all of these measures, but they have “developed important pieces of the puzzle,” the report said. Still others are moving in the right direction, among them Virginia, Hawaii, Michigan, Maine, Nevada, Delaware, New Mexico, Florida, Illinois and Utah.

U.S. Energy Use Declines, Renewables Increase

U.S. Energy Use Declines, Renewables Increase
August 26, 2010

California- A new government study shows that Americans are using less energy overall and making more use of renewable energy resources.

The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.

“Energy use tends to follow the level of economic activity, and that level declined last year. At the same time, higher efficiency appliances and vehicles reduced energy use even further,” said A.J. Simon, an LLNL energy systems analyst who develops the energy flow charts using data provided by the Department of Energy’s Energy Information Administration. “As a result, people and businesses are using less energy in general.”

The estimated U.S. energy use in 2009 equaled 94.6 quadrillion BTUs (“quads”), down from 99.2 quadrillion BTUs in 2008. (A BTU or British Thermal Unit is a unit of measurement for energy, and is equivalent to about 1.055 kilojoules). The average American household uses about 95 million BTU per year.

Energy use in the residential, commercial, industrial and transportation arenas all declined by .22, .09, 2.16 and .88 quads, respectively.

Wind power increased dramatically in 2009 to .70 quads of primary energy compared to .51 in 2008. Most of that energy is tied directly to electricity generation and thus helps decrease the use of coal for electricity production.

“The increase in renewables is a really good story, especially in the wind arena”, Simon said. “It’s a result of very good incentives and technological advancements. In 2009, the technology got better and the incentives remained relatively stable. The investments put in place for wind in previous years came online in 2009. Even better, there are more projects in the pipeline for 2010 and beyond.”

The significant decrease in coal used to produce electricity can be attributed to three factors:
  •  overall lower electricity demand
  •  a fuel shift to natural gas
  •  and an offset created by more wind power production

Nuclear energy use remained relatively flat in 2009. No new plants were added or taken offline in this interval, and the existing fleet operated slightly less than in 2008.

Of the 94.6 quads consumed, only 39.97 ended up as energy services. Energy services, such as lighting and machinery output, are harder to estimate than fuel consumption, Simon said.

The ratio of energy services to the total amount of energy used is a measure of the country’s energy efficiency.

Carbon emissions data are expected to be released later this year, but Simon suspects they will tell a similar story.

“The reduction in the use of natural gas, coal and petroleum is commensurate with a reduction in carbon emissions,” he said. “Simply said, people are doing less stuff. Therefore, they’re burning less fuel.”

Wind Energy From Airports?

Wind Energy From Airports?

By: Jeanne Roberts
August 19th, 2010

According to Phoenix, Arizona resident Dick Hales, the turbulence created by commercial jets sitting on the runway waiting to take off is a prime source of wind energy, but to date no one has thought of a way to harness it.

Jets sitting on the runway pre-takeoff can create wind speeds of up to 300 miles per hour. In the United States, where about 35,000 passenger jets take off daily, from more than 900 commercial airports, the potential for harnessing this wind power represents an enormous energy advantage to airports.

But Hales is stymied on two counts. His device, which consists of a reinforced housing containing a wind turbine, flywheel, and generator, needs a prototype. And the prototype needs financing.

Of course, Hales has a patent on the idea, which involves five FreeWind units mounted in front of a blast fence (many of which are already being used at airports), with two additional baffles to make sure the turbulence is directed at the blast fence and not dissipated. The entire assembly is located perpendicular of the runway and flight path, since Federal Aviation Agency (FAA) rules prohibit obstructing either.

Hales admits some have called him “crazy”. Hales retorts by asking why so many solutions embrace the obvious (that is, the status quo, which in this case involves a wind turbine on a tower hoping to catch a breeze). Then he points to the Wright brothers’, who were also considered crazy, along with such notables as John Baird (the TV camera), Crick and Watson (DNA), Robert Folk (nanobacteria), and of course Joseph Lister, who developed the sterile technique.

Hales got his vision for using jet turbulence to create power several decades ago. Acting on the advice of colleague and noted American designer, Ray Eames – who told Hales to “create your design in terms of product or need” – Hales, also an industrial designer by trade, decided recently to see if that dream could be revived.

Hales sees his invention providing instant energy for the hundreds of electric-powered airport vehicles currently in operation, and the hundreds more being considered to curb airport emissions (and, by extension, climate change). Take, for example, MSP (Minneapolis, St. Paul International Airport) where, in 2009, Metropolitan Airport Commission (MAC) officials installed wind turbines to power an electric vehicle as part of the MAC’s Stewards of Tomorrow’s Airport Resources (STAR) program launched in 2008.

The device could also be used to help power lighting at various non-critical locations around the airport. Which, if you think of how much electricity the average city airport uses, day and night, makes Hales crazy like a fox.

Hales recently got a positive response from Chrysalix Energy Venture Capital in Vancouver, BC. But Hales admits he isn’t an engineer, so he is seeking a university, design group or engineering firm with a solid grasp of wind energy fundamentals and a willingness to walk on the wild side.

Hales, who taught at the University of California at Irvine, and ran his own business in Irvine from 1984 to 2000, is currently semi-retired, after a decade of teaching at Arizona State University “off and on”. He now runs another business, and is – at 64 – still willing to put everything he has into his dream.

“I’ve been in business for 40 years, and am an expert in project management. I just need to convince someone to fund my idea and work with me.”

Emphasizing the clear need to find and develop every form of clean energy available – a need highlighted by the recent heat wave in Russia (triggered, most agree, by climate change), Hales admits he is currently scrambling to find people who know enough about the technology to create a working prototype.

“In the meantime, I will just keep experimenting with cardboard and glue.” Hales chuckles.

'Cool' Roofs- A Hot Idea?

'Cool' Roofs – A Hot Idea?
    By: Christopher Solomon
    MSN Real Estate

This hidden-in-plain-sight upgrade can mean saving on your electricity bills and enjoying a much more comfortable home during hot summers.

Linda Hanson is accustomed to long, hot summers, and she wanted to find a new way to reduce her cooling costs. Hanson owns a home in Canyon Lake, Calif. "The average temperatures out here are well in the 100s all summer long, so our (electricity) bills were $800 a month. It was pretty outrageous. We could not cool the house down. We'd run the air conditioner all the time." A big problem was the original concrete tile roof, which sat on the rafters and radiated that heat right into the house.

Then Hanson and her husband swapped out that roof for a so-called "cool roof" of green tiles on their 3,000-square-foot house. (They made other improvements, too, such as upgrading the home's windows and adding attic insulation.)

"We also put a swimming pool in, and even with that swimming pool, with the filter running, our bills in the summer are probably 200 bucks a month less," she says. The best part, she says, is "my house is comfortable all the time."

Hanson's savings may be dramatic, but they illustrate the point: Installing a cool roof is a hidden-in-plain-sight way to cool your home, shrink your electricity bill and help the planet. It's such a simple, smart idea that Energy Secretary Steven Chu endorsed the idea in a meeting with Nobel laureates last year.

An Old Idea Made New

Inhabitants of places such as Bermuda and the Greek isle of Santorini have long known that painting their roofs white to reflect sunlight can keep their homes cool. Studies bear that out: While black surfaces such as traditional built-up asphalt shingle roofs can reach 185 degrees, a roof that's white can be up to 70 degrees cooler because it bounces so much sunlight back into space. "The science of it is very basic," says Hashem Akbari, a leader in the study of cool roofs and a professor at Concordia University in Montreal.

Houses That Make Their Own Energy

Net-zero energy homes are gaining in popularity, but before buying a green home or an add-on product designed to generate energy, make sure you do your homework.

White roofs make sense particularly on commercial buildings because those buildings have their cooling systems on most of the year as computers and other machinery inside them create heat, says Chris Scruton, a project manager in the California Energy Commission's research program in building energy efficiency. With a white roof, "As much as 75 or even higher percent (of sunlight) can be reflected," Scruton says. That's great, you say, but what if you don't want a white roof on your Colonial? You're in luck. There's a roof for you, too.

Choose Your Hue

Manufacturers can make colored cool roofs that stay much cooler than traditional colored roofs. They add pigments or glazing to roofing materials that reflect infrared light back into space. That unseen infrared light makes up 52% of light that falls to Earth; we can't see it, but we feel it in the form of heat.

These cool roofs can take the form of tiles, shingles or metal. California's MCA Clay Roof Tile, for instance, makes 33 cool roof tiles, with reflectiveness ranging from just over 30% (for many of the dark-hued tiles) to 76% (for "White Buff"), says Yoshi Suzuki, president and CEO. Traditional dark asphalt roofs only have about 5% to 15% reflectiveness.

Custom-Bilt Metals of Chino, Calif., Classic Metal Roofing Systems of Piqua, Ohio, and other metal roof manufacturers have added pigments to their line of painted metal roof products.

"People are starting to catch on" to the benefits, Suzuki says, but "it's not so much residential yet." In 2007, about one-quarter of the commercial roofing market consisted of Energy Star-rated (that is, highly efficient) roofing products, compared with about 10% of the residential market.

The World's First Really Green Oil Deal

The World's First Really Green Oil Deal

By: Esmé McAvoy
Sunday, 8 August 2010











Ecuador's scheme to save its rainforest from exploitation could point the way to sparing other threatened landscapes.

The world's first genuinely green energy deal is about to be sealed. In a plan which could be a blueprint for saving large tracts of the planet from exploitation, a greater value is being put on a pristine wilderness than on the oil that lies beneath.

While the world's industrialized countries are building complex carbon markets to enable them to carry on polluting, Ecuador has come up with a much simpler idea for mitigating climate change: leave the oil underground. It is promising to lock up as much as a fifth of its oil reserves indefinitely, providing rich nations pay out at least half the market value of the oil – some $3.6bn – as compensation.

The trail-blazing proposal was first floated in 2007, but it took a step towards reality last week when the UN Development Programme signed an agreement with the Ecuadorean government to be the independent administrator for the project's trust fund. The accord makes Ecuador the only country in the world offering to leave lucrative oil reserves untapped in an attempt to slow climate change.

Crucially, the oil in question – some 846 billion barrels of crude – lies beneath the Yasuni National Park, one of the most bio-diverse swathes of rainforest on the planet. Located in the heart of the Ecuadorean Amazon, one hectare contains more tree species than the whole of the US and Canada combined. It is also home to 105 amphibian species – the UK has six – more than 500 birds, 200 mammals and countless insects and plants. Declared a world biosphere reserve by Unesco in 1989, the park is also the ancestral land of two of the world's last remaining uncontacted indigenous tribes, the Tagaeri and the Taromenane.

The plan, backed by Greenpeace, the WWF and even the oil-producing Opec countries – applies to a 675sq mile area of Yasuni known as the ITT block after the three oil-fields that lie beneath it. Locking up the oil would not only protect the rainforest and the indigenous tribes, but it would also stop at least 407 million metric tonnes of CO2 being released into the atmosphere, according to Carlos Larrea, the initiative's technical adviser. "That's more than the total annual emissions of France or Brazil," he said.

In return, Ecuador is asking for $3.6bn – roughly half the expected revenue if the oil was extracted and sold at current prices – to be invested in renewable energy developments to help the country further cut its carbon emissions.

If it works, the scheme could be rolled out to countries such as Colombia, Peru and the Philippines which face similarly stark choices between protecting globally significant ecosystems and oil. "Ecuador began exporting oil in 1972, and oil now accounts for over 60 per cent of exports," Mr Larrea said. "Locking away 20 per cent of our oil reserves is a bold decision but we can't do it without international support."

Yet, after three years, securing anything more concrete than praise has proved elusive. At the end of last year, President Rafael Correa embarked on an international tour, including the UK, France, Sweden and Canada, to drum up support for the proposal before December's climate change summit in Copenhagen. But none has offered a firm cash commitment.

The Yasuni-ITT committee was originally poised to sign the agreement at the summit, but Mr Correa, unhappy with the terms, baulked at the 11th hour. His actions, and subsequent statements, led to several resignations from the Yasuni-ITT board. But a new board was assembled, with some original members, and the contentious points in the agreement have been ironed out.

Despite the setbacks, Germany remains a supporter and is likely to contribute around $50m, although no figures are confirmed. Signing up an independent body such as the UN to oversee the trust fund was a key German criterion, along with the support of at least one other country. With the trust fund in place, Mr Larrea is confident the final obstacle will be removed. "Spain and Belgium have expressed support, as have a number of other European countries. We're very optimistic."

Contributions to the fund would be spread over at least 10 years and countries would be issued with Yasuni Guarantee Certificates (CGYs in Spanish) to the value of the non-emitted CO2 their contribution has secured. Should any future Ecuadorean government break the commitment and drill for oil, the certificates entitle their holders to their money back with interest.

Next month, individuals and private companies will also be able to donate via the Yasuni-ITT website. "We hope individuals and environmentally aware companies all over the world will be excited by what we're doing and want to contribute as a gesture of solidarity," Mr Larrea said. "Supporters will be symbolically 'buying' their barrel of oil with the guarantee it will stay underground." Such international "crowd funding" would create an intimidating network of public opposition should any future government try to break the pact.

The $3.6bn will be invested in renewable energy to reduce the country's oil dependency and cut carbon emissions. These investments are expected to generate annual returns of about 7 per cent, which will go into a second pot to fund environmental and social development projects, such as reforestation, social programmes for indigenous groups and eco-tourism. Projects will be decided by a steering committee of representatives from the Ecuadorean government, the donor countries and a nominated public representative.

Reducing illegal logging is the top priority, according to Mr Larrea. Ecuador has one of the highest rates of deforestation in South America, despite protected areas covering over a quarter of the country. Matt Finer of the environmental organisation Save America's Forests has called the Ecuadorean Amazon "a complicated and confusing array of overlapping protected areas, indigenous reserves and crude oil concessions", testament to the way conservation has regularly been sidelined by oil interests. Legal loopholes have permitted oil concessions within national park boundaries and even where areas are protected, they are woefully understaffed.

Ecuador's northern Amazon bears the scars of decades of reckless oil extraction. One of the biggest environmental lawsuits has been raging for 17 years between the oil giant Chevron and 30,000 Ecuadoreans whose land and water are contaminated by oil spills and toxic open waste pits. If found liable, Chevron faces damages of more than $27bn.

However, groundbreaking changes to the constitution in 2008 mean Ecuador is the only country in the world to recognise the rights of nature and ecosystems to survive and flourish, permitting any Ecuadorean citizen to sue on nature's behalf if these rights are infringed.

Understandably, the Ecuadorean government isn't prepared to wait for ever for international co-operation: "If by December 2011, Ecuador doesn't receive at least $100m, the government has the right to call off the proposal," said Bisrat Aklilu, the executive co-coordinator of the UN's multi-donor trust fund office that will administer the Yasuni fund. "The government will repay contributors the face value of their contribution and then make up their own minds about whether to drill."

For some, the plan amounts to little more than blackmail, with Mr Correa holding the Amazon to ransom; if Ecuador can get funding for Yasuni, what's to stop other countries cashing in? Saudi Arabia made possibly the most audacious bid for financial support yet this week, claiming compensation for the expected loss of oil revenue should climate change agreements result in a drop in production.

Against a backdrop of public outrage at the Gulf of Mexico oil spill, the argument for "post-oil" economies seems stronger than ever. Maria Espinosa, Ecuador's Heritage Minister, agrees. "Ten years from now projects like this will be the rule, not the exception," she said last week.
