Choosing the Right Siding

When selecting siding, there are six basic issues to consider:
1. Water Resistance. Water-resistant types of siding will have longer lifespans.

2. Ease of Installation. If you're installing the siding on your own, make sure it is within your skill set, requires no special tools, and creates no harmful dust when cut.

3. Energy Efficiency. Check the R-Value rating for energy savings and understand what will be needed as far as insulation beneath the cladding.

4. Aesthetics. Your siding will be in full view as you come and go, so make sure it is beautiful to you.

5. Versatility. Make sure the siding has the versatility to meet the varied needs of your specific project. If there are aspects of your home's exterior that will make using a particular type of siding more challenging than others, make sure you understand what the added costs or necessary adjustments will be.

6. Durability. Does it have the strength to resist temperature shifts present in your climate? How does it stand up to everyday wear and tear?

solar energy in the Midwest

Solar power heats up as costs drop, electric rates rise


By Steve Everly, The Kansas City Star, Mo.
Apr. 26--The prospects for solar energy in the Midwest are brightening.

Surprised? You shouldn't be.

The Midwest gets plenty of sunshine -- more than Germany, which uses more solar power than any other country. Kansas City has the same percentage of annual sunshine as San Antonio, for example, and Dodge City, Kan., has as much as Miami.

And the big cost considerations that for years have held back solar power in the region have changed. The price of solar panels has dropped substantially, and the Midwest's traditionally low electricity prices are on the rise.

Those factors came together recently for Tom Lawler, a Commerce Bank vice president. As coordinator of the bank's sustainability efforts, he has crunched the numbers on solar power for years. But this time he got a big surprise. They made economic sense.

The payback time for a solar panel project had plummeted from 25 years to just 10 years. As a result, Commerce this month is installing photovoltaic panels at its branch at 135th Street and State Line Road in Kansas City.
Area interest
Solar power still isn't a bargain, but many other Midwest businesses and homeowners are agreeing with Commerce: It has become a viable investment.

New solar customers range from a couple in Lee's Summit to Posty Cards, a Kansas City greeting card company that later this year will install the largest solar installation in Missouri. Kansas City Power & Light plans to have its first solar power installation up and running next year.

Ray Baisch of Lee's Summit is a retired custodian who worked at the Federal Reserve Bank in Kansas City. He believed President Jimmy Carter when he gave a speech in the late 1970s warning that the U.S. was wasting energy and relying too much on imported oil.

Baisch looked for ways to conserve and became a believer in solar energy, but he was put off by the cost. As recently as three years ago, a system for his home cost $38,000, but that price has come down to $30,000. Various government and utility incentives now cut that price in half for him. Baisch was the first KCP&L customer this year to take advantage of the utility's solar-installation rebates.

"If I had my way, every new house would come with solar already installed," he said.
Gaining traction
To be sure, solar energy remains in its infancy in the U.S., providing only 1/1000th of the country's electricity generation. But the amount of solar-generated electricity in U.S. homes doubled last year, and a growing number of businesses are jumping in. FedEx recently installed the largest rooftop solar installation in the country in Woodbridge, N.J., and Wal-Mart has solar installations supplying power to about 20 of its stores.

Overall, solar capacity for the first time moved above 2,000 megawatts, enough to power 350,000 homes, convincing many in the industry that solar is at a turning point.

Last year was the best ever for the U.S. solar industry, and 2010 is expected to be even better.

"We expect a breakout year," said Rhone Resch, chief executive officer of the Solar Energy Industries Association.

Solar has always been a tough sell in the Midwest, but several trends are helping make it more competitive:

--The cost of photovoltaic panels, which account for just over half of a solar installation, have plummeted 40 percent in the last year, thanks to cheaper prices for silicon and ample manufacturing capacity.

--Available incentives have never been more generous. Federal tax credits or grants are cutting the cost of commercial and residential solar installations by 30 percent. Businesses also can accelerate depreciation of their investment, helping recover their costs faster. Other incentives include the KCP&L rebate for its Missouri customers, which can lower a system's cost an additional 25 percent or so.

--The Midwest's low prices for conventionally generated electricity are going up. KCP&L, for example, will have raised rates about 40 percent in just a few years if its most recent rate request is granted.

--Several states, including Kansas and Missouri, are encouraging use of renewable energy, including requiring utilities to use more. Missouri's law specifically requires some solar use, and both states require utilities to buy excess renewable energy produced by households and businesses.
Evolving business
Solar power has had some success in the past, but mainly with solar thermal products such as water heaters and devices that provide warm air to heat homes. Those applications account for most of the solar energy used in the U.S., with paybacks of six to eight years.

But the idea of using nonpolluting sunshine to generate electricity has gripped the imagination of environmentalists and others for decades. The enthusiasm is easy to understand, given that all the energy stored in Earth's reserves of coal, oil and natural gas is matched by the energy from just 20 days of sunshine.

"I'd put my money on the sun and solar energy," Thomas Edison said in 1931.

A big step toward making that happen occurred in the early 1950s when a Bell Laboratories scientist found that a wafer of silicon exposed to sunshine produced electrons. That was the start of the photovoltaic panels used today to produce power.

Through the years, the technology improved, the price dropped, and the government and utilities have increased their incentives to adopt solar power.

The federal government has had a 30 percent tax credit for solar, but it was capped at $2,000. When that limit came off more than a year ago, inquiries increased, said Susan Brown, vice president of business development for the Energy Savings Store in Lenexa.

Her company has offered photovoltaic systems since it opened seven years ago. The first two years, it sold none. Since then it has sold 100, with the majority installed in the last two years.

Commercial property owners also are showing interest -- a big change from the past, when some who bought solar-equipped buildings had the panels removed because they didn't want to mess with them, said Phil Thomas, president of A.L. Huber.

His company constructs commercial buildings and recently installed photovoltaic panels at its Overland Park headquarters.

"Everyone now is interested in sustainability," Thomas said.

Commercial projects now are eligible for grants in place of tax credits, so they can get their 30 percent break on costs much sooner.
Taking the plunge
Erick Jessee, president of Posty Cards, was considering a solar project to meet 7 percent of his business's electric needs. He said the grant helped him decide to go for an even bigger installation, able to supply 11 percent of his electricity.

He considered other energy alternatives but settled on solar because his property didn't have the right soil for a geothermal heat pump, and wind turbines don't perform as well in urban areas.

His company's solar project, to be finished later this year, is part of a $6 million, 25,000-square-foot expansion of the company's plant. It will consist of 198 photovoltaic panels and is expected to be the largest solar installation in Missouri.

"We just want to do the right thing," Jessee said.

Still, Posty and others have to look at the economics. A 10-year payback was a bit longer than Commerce Bank would typically accept, but it was close enough to get the project serious consideration. The branch that is getting the solar panels will be a test to see how it works in "real world conditions," but Lawler doesn't think there will be many surprises.

"I don't think there are a lot of unknowns," he said.

Some of the toughest converts to solar could be the utilities themselves, in part because a generating-station-size project takes a lot of land.

Westar Energy, Kansas' biggest electric utility, hasn't rejected solar energy outright but says its preferred alternative is wind energy. The state ranks No. 2 in the country for wind-energy potential, and costs are lower.

"Right now, solar is still five or six times higher than with wind," said Don Ford, a project manager for Westar.

KCP&L doesn't disagree about the cost, but it's still going ahead with 4 megawatts of solar power next year. That will go toward meeting Missouri's renewable standard, and it will give the utility a chance to work with solar, which could become more important in the future.

The federal Energy Information Administration projects wind will be a tough competitor for solar for utility-scale installations. But it sees more growth for smaller solar installations in residences and commercial buildings.

KCP&L is pursuing that angle as well. The utility is installing 180 kilowatts of solar power in Kansas City's Green Impact Zone on schools, businesses and residences as a pilot project.

"In the future, this is going to be significant," said Kevin Bryant, vice president of energy solutions for KCP&L.

Part of an occasional series Wind farms and ethanol are familiar fixtures in the Midwest. But the region has little-known potential for virtually every unconventional energy source, from solar, geothermal and hydropower to cleaner ways to power our cars and trucks. In occasional stories throughout the year, energy reporter Steve Everly will explore and explain those possibilities -- and what's already under way.
------ Solar electricity in the Midwest Big advantage: The fuel is free, and the Midwest has sunshine to match Texas, Florida or just about anywhere in the country outside the desert Southwest.

Big drawback: Upfront costs, though those are coming down. Conventional electricity is still needed, especially at night.

Economic factors: Solar-panel costs are way down, and federal tax credits or grants can cut costs 30 percent. More utilities are helping with rebates, too. And with conventional electricity prices on the rise, the payback time for many solar projects has dropped by more than half.

Short-term potential: Electricity from home installations doubled last year, the best year so far for the industry, and 2010 is expected to be better.

Long-term potential: Promising for small scale, but uncertain for large-scale generation. Midwest utilities are focused more on wind power for their own alternate-energy electricity generation. ------

GE introduces Durathon battery for utilities

GE introduces Durathon battery for utilities


New Orleans, April 26, 2010 — GE Energy Storage Technologies, a unit of GE Transportation unveiled its Durathon battery technology for utility companies.

As part of a simple energy storage system, GE’s Durathon battery provides an alternative to costly new power structures, which enables energy to be used when needed.

“Utility companies are facing unprecedented challenges and we’re working with them to create a better energy system, one that can bring energy to customers where it’s needed, when it’s needed, efficiently and for the best price,” said Prescott Logan General Manager GE Energy Storage Technologies. “GE’s Durathon battery technology has been developed to change the future of power generation, transmission and distribution for end users around the globe.”

Because of its proprietary chemistry, the Durathon battery has the ability to last up to two decades while providing optimal charge and discharge times. Durathon batteries are suited for applications in extreme temperature environments because the need for an expensive controlled environment is not required to deliver peak performance.

This minimizes installation costs along with the batteries high energy density. The Durathon battery technology has been developed to support a broad range of utility-oriented applications, such as: transmission and distribution upgrade deferral, time shifting, congestion relief, peak shaving, load following and reserve capacity.

Additionally, it will support end-user applications such as time of use (TOU) management, demand charge reduction, and power quality improvement.

GE’s new battery plant will be located in Schenectady, New York, and is expected to create 350 new jobs in the region.

The facility has the advantage of being in close proximity to GE Global Research in Niskayuna, where researchers will continue to work on enhancements to the battery chemistry and related systems technology.

GE is making a $150 million investment to build upon the Durathon battery technology through the development of new materials, new manufacturing technologies and intelligent controls.

Searchable database- chemical hazard, exposure and toxicity data



WASHINGTON – The U.S. Environmental Protection Agency (EPA) is making it easier to find chemical information online. EPA is releasing a database, called ToxRefDB, which allows scientists and the interested public to search and download thousands of toxicity testing results on hundreds of chemicals. ToxRefDB captures 30 years and $2 billion of testing results.

“Tens of thousands of chemicals are in commerce and current chemical testing is expensive and time consuming. Results from chemical testing are scattered throughout different sources,” said Dr. Robert Kavlock, director of EPA’s National Center for Computational Toxicology. “ToxRefDB allows the public to search, find and compare available studies about chemical toxicity and potential health effects.”

ToxRefDB provides detailed chemical toxicity data in an accessible format. It is a part of ACToR (Aggregated Computational Toxicology Resource), an online data warehouse that collects data from about 500 public sources on tens of thousands of environmentally relevant chemicals, including several hundred in ToxRefDB. Those interested in chemical toxicity can query a specific chemical and find all available public hazard, exposure, and risk-assessment data, as well as previously unpublished studies related to cancer, reproductive, and developmental toxicity.

ToxRefDB connects to an EPA chemical screening tool called ToxCast. ToxCast is a multi-year, multi-million dollar effort that uses advanced science tools to help understand biological processes impacted by chemicals that may lead to adverse health effects. ToxCast currently includes 500 fast, automated chemical screening tests that have assessed over 300 environmental chemicals. ToxRefDB, along with ACToR, allows users to take advantage of this linkage to find and download these results.

ToxRefDB contains toxicity information that forms the basis for pesticide risk assessments when combined with other sources of information, such as those on exposure and metabolism.

Retrofit reduces energy use by 60 percent

Pilot Project Super Insulation for Older Homes at Massachusetts home
You could call it an "Extreme Makeover: Energy-Efficient Edition."


In Arlington, Mass., Alex Cheimets and Cynthia Page live in a duplex that used to consume about 1,400 gallons of heating oil a year. Now their building will soon be one of the most energy-efficient in its New England neighborhood, thanks to a pilot project that retrofitted the structure with almost $100,000 worth of insulation and other products to increase energy efficiency and decrease utility costs.

The so-called Massachusetts Super Insulation Project seeks to determine the benefits and cost effectiveness of retrofitting old energy-wasting houses with insulation upgrades in key areas. Though the cost for the upgrades in the home were substantial, some of the techniques used—such as proper air-sealing and adequate moisture barriers—could easily be applied to new construction and for not much more money.

Massachusetts officials are keenly interested in the results of the project, which dovetails with the state’s efforts to become more energy-efficient. “Our governor, the state House and Senate, and the executive branch are aware that the nation’s energy strategy is not acceptable, and a big part of it is the existing housing stock,” says Philip Giudice, commissioner of the state's Department of Energy Resources.

“Nationally, buildings account for 40 percent of all energy consumption and one-third of all greenhouse gas emissions,” says Energy and Environmental Affairs Secretary Ian Bowles, who chairs Massachusetts Gov. Deval Patrick’s Zero Net Energy Buildings Task Force. “This super-insulation project in Arlington promises to be a model for the type of innovation in the building industry that the Patrick administration hopes will soon be widespread across Massachusetts.”

The public/private effort includes the state Department of Energy Resources, the local utility NStar Electric & Gas, and a number of building product sponsors.

Bowles is right, of course. As green building practices spread through the new construction market, America’s existing housing stock remains an energy-use problem. Millions of these old structures lose large amounts of energy through leaky windows, inefficient heating and cooling units, and poorly insulated walls, all of which contribute to higher-than-necessary utility bills. The 3,200-square-foot Cheimets/Page building—divided into one condo for Cheimets and his family and one for Page—was one of these structures.

At one point when home heating oil in the Massachusetts area hit $4.69 a gallon, Cheimets says, the homeowners were paying a combined total of almost $6,500 a year for heating and hot water. “We needed to replace our siding and our roof soon anyway,” Cheimets says. “As a duplex, we could simply do the minimum or we could invest now to save later. Super-insulation was the better financial investment.”


The parties in the pilot wanted to demonstrate that it’s possible to bring an existing building up to the highest standards of energy performance. In addition to reducing energy use by between 65 percent and 70 percent, the group was also interested in exploring super-insulation as part of an overall program of energy efficiency and carbon reduction. Finally, it hoped to use the Arlington, Mass., pilot project to determine cost-effective retrofit recommendations for homeowner renovations; develop experience with and collect performance results for existing structures; and establish criteria for future state programs supporting residential super-insulation projects.


Before the work commenced, the project team consulted with Somerville, Mass.-based Building Science Corp., which performed energy parametric simulations, analysis, and economic payback comparisons of various energy retrofits options.

As a result, the extensive retrofit focused on tightening the building envelope, which included new doors and the replacement of the single pane windows. The team installed double-pane Pella fiberglass windows with low-E glazing, Tyvek stucco wrap, two layers of 2-inch Dow closed-cell foam board, furring strips, and NuCedar cellular PVC siding. They ripped off the old roof and installed two layers of 3-inch foam board on the roof deck, followed by plywood sheathing, and light-colored asphalt shingles. They also sprayed Icynene open-cell foam in the attic roof and in the basement rim joists and ceiling. Finally, the team installed a heat recovery ventilator and an on-demand water heater.

Cheimets says the upgrade have made a big difference in the comfort level of the units and in the performance of the building. “I felt the difference immediately,” he says. “There are fewer drafts and no cold spots; that’s all gone away, and we have seen about a 60 percent reduction in energy use.”

As part of the pilot project, DER and NStar have installed sensors to monitor real-time oil usage as well as temperature and humidity levels inside and outside the house. “We were using about nine gallons a day before, but now we’re using three on average,” Cheimets says.

The reduction in the building’s ongoing energy use has come at a steep one-time price tag. Overall, the retrofit cost more than $90,000, and like most renovation projects, ended up being more expensive than expected in different areas.

For example, the cost for the roof replacement was first estimated at $10,000, but the price tag nearly doubled by an additional $9,000 with the addition of super-insulation. Replacing the siding was projected to run $30,000, but it increased by $41,000 with super-insulation and re-flashing the windows. An additional $6,000 went toward the installation of expanding foam in the basement ceiling; $4,000 paid for heat recovery ventilators.

“If you look at the additional cost of super insulating (compared with just doing the required work in ‘standard’ fashion) doing this work is an additional cost of $50,000, or $25,000 per family” in the two-unit duplex, according to program documents.

While the costs are high, Cheimets says they should be taken in context of retrofitting an 80-year-old house that featured 50 windows and suffered from bad insulation from the start. Doing such upgrades in new construction would be cheaper. “If you’re building a new house, you would be taking certain things into consideration like facing the roof south, using fewer windows, and decreasing the amount of angles in the roof,” he says.

John Dennis Murphey agrees that using such strategies would absolutely make such a remodel cheaper. “That’s what we’re doing now on one house,” says the principal of Chevy Chase, Md.-based Meditch Murphey Architects.

There are also other ways to save money on such a project. Murphey, for example, has eliminated conventional sheathing from his houses all together. Instead, he uses 2 x 6 studs, spray foam insulation, and metal bracing to make the studs rigid. “The studs are energy highways,” he says. He then wraps his houses in 1.5 inches of foam board, which creates a thermal break.

Instead of simply balking at the added costs, though, Murphey says builders and consumers should look at the overall project and the long-term benefits. “Energy prices have come down, but who knows where the price of oil will go,” he continues. “My bet is that they will go up. I’ll take that bet every time.”

Members of the Super Insulation Project would probably agree. It is estimated that the annual savings to the homeowners will be $2,350 to $4,000 per year. “At the current heating oil cost of approximately $2.35 a gallon, it's a 20-year payback,” program documents say. “But a few short weeks ago the price was closer to $4 a gallon, and the price of oil is likely to rise again in the coming years, dramatically shortening the payback period.”
