INNOVATION TO CUT ELECTRIC VEHICLE COSTS. 
by Bruce Mulliken, Green Energy News

Oil has a long and promising future.

Some of you probably didn’t want to hear that.

According to an in-depth story in the New York Times, new discoveries and new methods of extracting oil are opening up a new chapter: Oil could last another 60 years. New discoveries off the West Coast of Africa and its jigsaw puzzle mate, the East Coast of South America, as well as the soon to be ice-free Arctic as well as waters off Cuba and in the Mediterranean all will add to the global supply. Further, the expansion of squeezing oil from sand is creating a long term supply.

The article mentions only in passing the effect continued guzzling will have on the planet.

There’s no reason to disbelieve the findings of this story.

Will governments of the world make laws that slow the consumption of all this newly accessible oil? Some may try. But don’t count on it.

The only way to stop this inundation is to find a way to make clean alternatives such as electric vehicles far cheaper. That’s a message to EV car companies: Innovate, innovate, innovate to cut costs.

KleenSpeed Technologies, of California, is building an electric vehicle prototype that could potentially be a step in that direction. KleenSpeed calls it KAR. I’ll let words from the company explain:

“The KAR concept is based on a complete rolling platform designed and engineered by KleenSpeed which will be fitted with a variety of alternative body modules.

“The KAR Platform is under development now and the first prototype version of the body module is now being modified at KleenSpeed to drop on to the KAR Platform prototype.

“In keeping with the core values of the KleenSpeed brand, our first production EV will emphasize the driving enthusiast’s perspective. It will be fast, provide crisp and sporty handling, and be really fun to drive. The KleenSpeed KAR VX-1 will also be a real world viable 2-passenger electric vehicle that sets new benchmarks in value, efficiency, performance and EV technology.

“The VX-1 is the first in a series of EVs based on the KAR Platform technologies. A 4-passenger sedan will be developed next, followed by other body configurations …. All offering the KleenSpeed EV experience.

KAR Platform Details

KAR ESS

“The KAR ESS is the heart of the KAR Platform. The scalable ESS will feature thermal control and a self-contained enclosure with modular battery packs to allow for simple size and power variations. The largest version will provide 40 kWh of energy and deliver sports car performance and a real-world range of 120 -140 miles.

KAR PLATFORM

“The KAR PLATFORM incorporates a unitized controller/motor/drivetrain package mounted via rear subframe. The low profile ESS mounts under the floor of all body styles to provide a low center of gravity for responsive handling. Steering and front suspension are also incorporated into a modular subframe design. All three main subassemblies will be joined by a lightweight platform perimeter frame to comprise a complete rolling chassis.

KAR VEHICLE INTEGRATION

“The KAR Platform is intended to accept a variety of body units to create a full line of E vehicles : a 2 passenger coupe, a 4 passenger sedan, a utility vehicle with a compact pick-up bed, a panel van and a mini SUV are all possible options sharing the common platform. This modular design concept considerably reduces costs to market a full range of vehicle types suited to niche markets.”

The platform will weigh a maximum of 1450 lbs. With a body about 2600 lbs. A 134 hp, 100 kW electric motor will drive the rear wheels.

The approach is actually a return to the past when all cars were made on a body and frame , or chassis, platform that truck companies still use.

The company’s other products include the Eiata, a kit to convert Mazda Miatas to electric drive, a selection of e-bikes and e-scooters, and an electric kart.

“Green”ing up Old Homes

29 06 2011





Old Home Goes Geo Thermal

29 06 2011

LANCASTER COUNTY, PA. — Maintaining the historical aesthetics of an old stone home while reaping the benefits of the newest geothermal technology can be a challenge. Especially if no central HVAC system preceded the arrival of new systems.

Fortunately for the Proud family that’s the type of work Pennsylvania-based Vertex Mechanical specializes in.

The Prouds purchased the property and the old stone homestead in 2001. Built in 1851, their 4,700-sq.ft., seven bedroom home required a lot of TLC before it became the historical showcase it is today. When they decided to restore the home, the Prouds wanted to maintain its old-world charm, and Vertex Mechanical rose to the challenge.

The task would require installing mechanical systems in a house that had no previous ductwork, all without ruining the historical feel and appearance of the home. Great diligence was required to hide ducts, and they had to deal with a fat fieldstone foundation and walls, in some places 3-ft. thick.

“The old home had its own bag of tricks for us to deal with, complicating the mission at every turn, but we eventually found a solution to all of the challenges,” said Vincent Youndt, president of Vertex Mechanical.
“I was very impressed with Vince’s eagerness to keep the integrity of our historic home intact,” said Susan Proud.

Before deciding on what system to install and what contractor to go with, Susan Proud spent months researching new mechanical system possibilities for the home. Since Susan and her husband, Spencer own Abacus Sports Installations, a firm that installs green and U.S. Green Building Council LEED accredited recycled rubber floors, they are both familiar with sustainable products and technology, and they are passionate about the environment too.

“I’ve always had a desire to do what’s right for the environment,” said Susan.

And so, she spent time researching mechanical systems on the web, spoke with several manufacturers and mechanical contracting firms, and visited regional home shows to learn about the variety of systems available. Her search led her to explore the possibility of geothermal heating and cooling. She knew that the installation she was looking for would be an important investment.

Susan was adamant that the equipment, and the workmanship, be the best she could buy. After all, their new (old) home is one they plan to raise their family in (Susan and Spencer have four boys). She even asked several local well drillers who they thought was best qualified to do geothermal installations. More than any other company, Vertex was recommended.

“We specialize in mechanical systems for historical homes and buildings,” explained Youndt. “We practice what we preach [the firm’s shop is an old, brick, five-story tobacco warehouse, renovated and outfitted with a ClimateMaster geothermal system]. Geothermal systems are so flexible. You can do almost anything with the variety of systems manufacturers offer today: forced air, hydronics, radiant heat, dehumidification, integration with solar and so much more.”

One ‘proud’ system

The Proud’s home has two ClimateMaster Tranquility geothermal water-to-air systems. A three-ton TTVO38 packaged system located in the basement takes care of the first floor while a three-ton TTS038 split system handles the upstairs. The gables are vented with a fan to evacuate warm air in the summer.

“We especially like using split systems,” said Youndt. “These enable us to place a condensing unit in the basement where it should be, and from there run refrigerant lines to an attic air handler which, as it turned out, worked perfectly at the Proud’s home.”

Both systems share a six-ton (total of 600 lineal feet) bore hole. What sets this apart from most geothermal applications is the way the systems are used.

According to Youndt, the Proud’s geo systems are not typically run simultaneously at full capacity. In the winter, the downstairs packaged system runs primarily in first stage cycling into second stage as temps go down. Using the entire six-ton capacity of the bore hole for the three-ton unit raises its maximum performance.

In the summer, the roles are reversed. The upstairs split-system runs full time in first stage, cycling into second stage as needed, utilizing the first floor mostly in first stage. In both cases, the opposing system is not running very hard, thus increasing entire system efficiency.

To run ducts, all floorboards were removed and the flexible duct was run against the floor joists. Blown insulation was used to fill the joist bays, and the flooring was laid back down.

“We use high quality flex duct,” said Youndt. “We can’t afford to use a duct that’s going to give out in 10 years.”

The walls remain stone on both sides, which was a key consideration when calculating the unusually high heat load of the old home. Compared to a modern stick built house, Proud’s home is shedding as much thermal energy as a building twice its size.

Going green

In the few years prior to the retrofit, the Prouds were paying between $8,000 and $10,000 a year for all electric and fuel oil. The number dropped to $4,400 for the first year after the system was installed.

“It’s sure nice to have central air conditioning as well as being environmentally friendly and saving money,” said Susan. “We also have family overseas, and when they come to visit, they stay for a long time. We didn’t like the idea of running out of hot water.”

Domestic hot water is provided by a desuperheater and two 50-gal. Bradford White water heaters.

“The first water heater in line acts as the buffer tank for the geo, with no electrical power to it,” explained Youndt. “The second tank maintains the top end of the water heating temp, and is also there for shoulder season back-up heat when geo systems aren’t running steadily.”

“It’s been my dream to have a self-sustaining, off-the-grid house, some day complete with a power-generating wind turbine and photovoltaic panels, too,” said Susan. “The geothermal system is the first step in our plan for making renewable energy a bigger reality here. I guess that means we’re going green, all the way.”

 





Craftsman Green Renovation

20 06 2011

From Signonsandiego.com

When seeing the exterior of artist Doug Kipperman’s 1917 bungalow in South Park, no one would guess the eco-friendly house to be a century old.

The inviting front porch, stained-glass pieces, well-furnished gumwood paneling and beautiful country-style backyard could be deceiving. However, the importance of sustaining the environment and its people is what led Kipperman to improve the old home.

After stumbling across its sale in 2004, Kipperman and his wife immediately fell in love with the original craftsmanship and felt the need to bring the charming details of the house back to life. Patience with the long renovating process has given him and his family a beautiful space to call home sweet home.

To find inspiration for your living space, view this sustainable house along with four other homes showcased at this year’s Old House Fair, now in its 13th year and presented by the South Park Business Group and the Greater Golden Hill Community Development Corp.

Q: How long did it take to refurbish the house?

A: The physical building took about seven to eight months, but the property is evolving. The gardening took a little over a year, but the overall yard took about over three years. It’s been on a project-by-project basis. Our next project is a “living wall” on the backyard deck. It will be a tapestry with real plants and backlit stained glass. However, we’re calling it an “eternal wall,” because my attitude is to make sure it lasts for the rest of my life.

Q: What led you to want to renovate the house?

A: The place was a diaster. It was neglected for a lot of years, but we just fell in love with the craftsmanship. We sat for six hours talking to the owner. There was this warmth, beauty and craftsmanship about the house that we don’t see anymore. Nowadays, we are in such a hurry we forget about before. We wanted to maintain the spirit of the craftsmanship, but put in our own personality.

Q: What was the most challenging aspect when fixing the house?

A: To make it safe. To make it a healthy environment. The construction and materials that are sustainable were not readily available, so it was hard, but it was important to make it safe. And accessible.

Q: Any advice for people who are interested in repairing their old homes?

A: Be patient and have deep pockets. Make sure people you work with know what you want. We’ve been blessed with the people we’ve worked with. Know the repertoire of the contractor. I talked to customers of contractors to know how they worked.

Q: Why did you feel it is important to show your house at the Old House Fair?

A: Pride. We’re proud of our house. As an artist, I look at a lot of different things, and I like to put my own signature on it. I look at everything and inspire to create my own art. Hopefully this will inspire others.

A Green LEEDer of Coronado

17 06 2011

Give Lorton Mitchell a blank piece of paper and a piece of land and watch him go to work. The longtime Coronado builder and third-generation Coronadan has been creating beautiful homes here since 1983. He also just gave Coronado a special honor–a gold medal.

Lorton Mitchell Custom Homes received special accolades by winning the Leadership in Energy & Environmental Design (LEED) Gold Certification for Bella Vista, their latest project at 701 First St. This is Coronado’s first Gold LEED Certification for a home and speaks volumes about the contractor’s dedication to protecting Coronado’s landscape.

LEED is an internationally recognized green building certification system. Achieving LEED recognition is not easy. It involves extreme effort on behalf of the architects, designers and builders from conception to completion. It adds time and expense to a project, but the end result radiates from the intense preparations that go into it.

A LEED winner must focus on energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impact on the surrounding homes and area.

The architectural visionary for Bella Vista was Coronado’s Dorothy Howard, who worked hard to add a level of detail typically reserved for the highest examples of Spanish Revival architecture.

The interior design team of Stephanie Davis and Mark Pugh (Davis-Pugh Inc.) made sure nothing inside the house competed with or distracted from the rare, seaside view the location presented.

“Lots of thought went into this,” said Mitchell. “Big houses are at a disadvantage for LEED presentations right off, so we knew going in that we had our work cut out for us. Still, we did this because it was the right thing to do. Our whole criterion was based on achieving this end result. We’re very pleased.”

When driving by Bella Vista, it’s not readily apparent what treasures lie within those unpretentious Spanish-styled walls. “We intentionally wanted to blend into the neighboring community no matter how difficult the challenge,” said Mitchell. “It would have been easy to create a grand palace with large, heavy doors and a massive presence. Certainly the size of the property could have sustained such a palace.”

Indeed, it took real sensitivity to walk through a vacant lot and see so ambitious a goal–a home that consisted of understated elegance and cutting-edge green technology, the likes of which Coronado has never seen.

Energy efficient and environmentally sensitive features include heated floors, hidden photovoltaic and hot water solar panels on the roof. Twelve individual zones throughout the home allow for you to heat or cool each room independent of the others to suit the occupant’s comfort level.

Bella Vista probably has the most sophisticated heating and cooling system in Coronado, but the irony is that the home is so well oriented and insulated that you would seldom need to employ it, said Mitchell.

The area in and around 701 First St. has had quite a history. Two hit TV series were filmed on this stretch of beach–Harry O with David Janssen and Coronado 9 with Rod Cameron.

Large car-carrying ferryboats plied the waters in Bella Vista’s front yard from 1886 through 1969. Before that, pioneer aviator Glen Curtiss landed his airplane on that stretch of dirt, and before that, Kumeyaay Indians foraged for food along these banks.

The history of this stretch of bayside beach was not lost on Mitchell. He grew up just two blocks away. “I designed and built my first boat on this beach when I was 11,” he said with a twinge of irony.

Most days, as the twilight hues engulf San Diego Bay, Mitchell can be found on his large paddleboard maneuvering along the waters just off Bella Vista, admiring his handiwork and appropriately feeling a larger part of that history.

Bella Vista is featured on the cover of this month’s San Diego Home/Garden Lifestyles Magazine, a major prize unto itself. The article, by veteran journalist David Coddon, starts out, “Coronado’s Bella Vista manse is architecturally supreme, responsibly green and a sight to be seen.”

The home is unpretentious, yet unbridled elegance. Of the roughly 38 lots on this bay side of First Street, Bella Vista is one of the few homes where bay and street lots are combined. “Someone rich and famous could live here and no one would know,” said Mitchell.

Bella Vista measures just over 9,000 square feet and boasts seven bedrooms and nine bathrooms within its walls. This includes a two-bedroom, two-bath casita in the rear and an enclosed garage that can house up to eight cars. An oversized turntable (designed by Coronadans Bill Gise and Jim Newhall) allows cars to be moved around like Tonka Toys.

There is a separate prep-kitchen and an elegant wine vault, both of which lend the house to large parties and fundraisers. Spacious rooms and patios seemingly beg to host major events. Clearly comfort was a top priority with the design team.

Walking through the house you are immediately struck by the natural lighting, the windows looking out on to San Diego Bay, the vaulted, exposed beam ceilings and adherence to the lovely arches used so predominantly in construction of the early Spanish missions.

The entire home gently steps down to the water to avoid a heavy presence, and offers a breathtaking 180-degree view that takes in San Diego Bay from the Coronado Bridge north to Point Loma.

Mitchell’s previous projects have demonstrated a wide variety ranging from quaint alley homes to large estates along the golf course. For years he has held a fascination with Santa Barbara Spanish-style homes, which is romantically evident in this latest project.

“Over the years I’ve seen many homes that literally die after 30 years. They were built in haste, and without a lot of concern about what materials or techniques were employed,” said the popular builder.

“Seeing that makes me want to build homes that will last, that will enhance the property and the neighborhood, that will stand the test of time. I fully expect our homes to last 100 years or more,” said Mitchell.

Bella Vista, the waterfront home at 701 First St., took 16 careful months to create. It is currently on the market. Lorton Mitchell Custom Homes has more than 100 completed projects in Coronado. For more information call 619-435-3446 or visit their website atwww.lortonmitchellhomes.com.





LEED Approved Craftsman Style Home

13 06 2011

According to its LEED for Homes score, the Gottfried family’s East Bay craftsman is the greenest private home in America. Fortunately, when they decided to retrofit the house for a greener lifestyle, they chose to keep the beautiful craftsman bones intact. The result is an amazingly harmonious combination of early-20th-century style with innovative new systems for everyday conservation, including wastewater recycling and solar energy.

Backstory. David Gottfried is the founder of the U.S. Green Building Council, and so when his family bought the long-neglected 1915 bungalow, they were determined to make it as green as green could be. Their decision to move in the first place was inspired by a desire to reduce their footprint; they went from a 2,600 square foot house high up in the hills to 1,500 square feet in a walkable neighborhood near a BART station. To eliminate his commute entirely, Gottfried built a home office, a LifePod shed in the yard powered by solar, and heated by the sun as well through an all-glass wall.

Green Details. All of the paints used in the bungalow’s renovation were zero-VOC paints by Mythic. Celluose insulation, recycled from newsprint, was blown into the existing walls through small holes drilled in the wood paneling. A gray water recycling system nourishes the native plantings in the yard, and also provides water to the house’s toilets. Solar panels bring the family’s electric bill down to net zero by feeding energy back into the grid on sunny days. And for the bungalow’s exterior stairs, which needed to be replaced, the family chose wood from a century-old bridge in Sacramento.





Energy Efficient Windows and What it Means to You

10 06 2011


According to the U.S. Department of Energy, leaky and inefficient windows, skylights and doors account for up to 25 percent of the average household’s energy bills. Some sources estimate as high as 40 percent. A lot depends on where you live:

Cold climates lose energy in the form of heat

Hot climates lose energy in the form of cooling

The colder or hotter the climate, the greater your heating or cooling costs and the greater potential you have to save money on energy costs. Nearly everyone can benefit by replacing leaky, inefficient windows with modern energy-efficient windows. Depending on your location, you can cut energy costs by as much as 15 percent.

A Smart Investment

NFRC Label
Replacing all of a home’s windows can be a big investment. The good news is, it’s an investment that can pay for itself in just a few years. Here’s how:

- Improves curb appeal and increases resale value. According to the 2008/09 Cost vs. Value Report (a combined effort by Remodeling magazine and REALTOR® magazine), homeowners can expect to recoup about 93% percent for vinyl or wood window replacement.

- Reduces heating and/or cooling costs, which saves you money every year.

- Increases the comfort of your home.

- Can qualify you for rebates and tax incentives.

 

Thoughts with Pat:


When I’m out showing places with clients I have found that windows play a large role in the decision making process. There are a large majority of older homes in San Diego that still use the older metal framed window. These windows tend to let in more noise, heat and generally look dated. When clients see that the windows have been updated to energy efficient windows it makes their decision much easier because they know that at some level their lives at home with be just a little more comfortable. If you live in an older home with older window, consider upgrading to new Energy Efficient Windows, you might just save a penny or two.





Zillow releases mortgage app for iPhone

9 06 2011

Real estate website Zillow.com on Tuesday joined the saturated mortgage app market with one of its own.

The tool, available to only iPhoneusers, lets you calculate:

-Your estimated mortgage paymenton a potential purchase.

-How much home you can afford.

-What you would roughly pay if you refinanced.

When you launch the app, you’ll see a chart showing the performance of the 30-year fixed rate, which fell last week to its lowest level this year.

Below you’ll see three calculators, and within each one, you can manipulate a number a features to get an estimate of how much you’d owe in a home loan.


Likes: What sets the Zillow app apart from other mortgage apps is its simple design interface and the attention to detail within the calculators, which is important when deciding on a big payment such as a mortgage.

It’s nice that you can immediately visualize your mortgage payment in a pie chart as you manipulate price, the down payment and interest rate. You can see similar visuals in the affordability and refinancing calculators within the app.

Dislikes: The slide bars that let you decrease and increase the field amounts are finicky. But I realized you can just tap the fields and input figures using the number pad. It would be helpful if the app developers made that option more visible.

Zillow also should consider making an Android version. The Guardian, a publication in the U.K., reported last year that Google was activating 160,000 mobile phones that the Android operating system daily. Read that story here.

See a preview of how it works, and try it yourself by searching “Zillow Mortgage Marketplace” in the App store.
