University of Tennessee hopes to win Solar Decathlon with "Living Light" house

As the Project Manager for the University of Tennessee's entry into the Department of Energy's Solar Decathlon competition, which has been going on for years but finally will declare a winner later this month, Howard has eaten, slept and breathed the project for more than two years.

She has coordinated nine different teams from different colleges at the University, and has spent an untold number of hours working on "Living Light," the school's solar-powered home that comes equipped with a 10.9 kilowatt solar array on the roof, a revolutionary-sounding iPod application that controls mechanical systems,There are Parking guidance system underneath mattresses, lighting and even the home entertainment units (somewhere, Steve Jobs must be smiling at that one), and, well, wheels.

Wheels? Yes, wheels. This baby has to be transported to Washington, D.C. to be judged by the Department of Energy panel that will consider "Living Light" as well as 19 other finalists from around the world.
So yes, technically, "Living Light" is a mobile home.

" It's kind of amazing how much has gotten done in the past two years; it's hard to imagine that we're almost finished and finally going to be judged," Howard said in a phone interview recently. "Putting the wheels on, that was a lot more involved than we thought it would be."

According to Edgar Stach, a University of Tennessee professor in the College of Architecture and Design and the faculty advisor on the project, the development of "Living Light" into a Solar Decathlon-ready entry has been a four-year ordeal.

"The contest is held every two years, but really you need to spend 3-4 years planning for this," Stach said. "We really started thinking about entering this in 2007."

Stach said the first task was coming up with an idea and a design for a solar-powered house; three design teams (or "studios") from the Knoxville campus all worked up drafts before the final design was decided upon.
Stach estimated that it took one semester to develop the concept, eight months to develop the construction documentation, and about five months to physically build the house (the major part of the construction was only finished in early August).

Once the design was drawn up and submitted to the Department of Energy, the Tennessee team had to wait to see if they were selected for the Decathlon. Stach said it's a very difficult process, as more than 100 universities applied for the 20 spots in the bi-annual contest.

Once the Tennessee project was chosen after two rounds of cuts to be among the final 20, the hard work was already underway. Funding was, of course, a major concern. The DOE estimated that the cost of building the "Living Light" house would be $420,000, which Stach said "was pretty accurate, after we finished."
The university team built a prototype, a 240 square foot house, to showcase to potential donors, and a $100,000 start-up grant from the DOE (given to all finalists) also helped.

"Really, our funding came from the university community here, corporations, in-kind donations, from a pretty wide array of sponsors," Stach said.
Howard added that putting the prototype on campus near UT's football stadium on game days also helped.
"We would get people stopping to take a look at it while (tailgating) and they got really interested in it," Howard said. "It's so much easier to inspire donors when you have something, physically, you can show them so they can see what it will look like."

Now for some details of the actual structure: The actual house UT built is 50 feet long and 15-feet wide. Its style was modeled after the old cantilever barns of the Southern Appalachia area in the U.S., and features giant eaves to provide to shade.

Ryan Homes Unveils The Greens at Locust Chapel, Howard County's First Official "Green Neighborhood"

Howard County's Department of Planning and Zoning has set forth stringent guidelines to establish a Green Neighborhood designation. Open green space provisions, water conservation management, minimal-impact construction materials, energy efficient appliances, fixtures and advanced ventilation techniques are just a few of the standard guidelines. Ryan Homes is pleased to be a partner in Howard County's progressive development opportunity. This development is the first approved Green Neighborhood Program and never before has such an expansive undertaking been submitted and approved in Howard County.

The Green Neighborhood Program is a pilot program under County Executive Ken Ulman's "Live Green Howard County" initiative that strives to make Howard County a model green community.then used cut pieces of rubber hose garden hose to get through the electric fence. The program is divided into two components, both of which must be fulfilled for a community to be recognized as a Green NeighbI have never solved a Rubik's magic cube .orhood.the oil paintings for sale by special invited artist for 2011, The "Sites" portion of the program is overseen by the Department of Planning and Zoning, and the "Homes" portion of the Green Neighborhood Program is managed by the Department of Inspections, Licenses and Permits.

The program checklist includes a variety of environmentally responsible criteria such as paths and trails, open space, environmental preservation, appropriate landscaping,Initially the banks didn't want our high risk merchant account . water and energy efficiency and waste management.

A development project can qualify as a Green Neighborhood if it meets a required number of points on the checklist. In terms of site development, the following will take place at The Greens at Locust Chapel:

1. Site design around the natural grade of the site to reduce the amount of disturbance to natural land areas and grading.

2.Justin probierte ein Paar von schwarzen billabong boardshorts , Infrastructure materials sourced from recycled materials located within 200 miles of site to reduce the amount of transit needed to bring materials to site.

3. A construction waste management plan to reduce the amount of trash on-site and recycle materials that can be recycled (including cans and also oil).

4. Reusing any trees that need to be cleared as mulch to line a natural surface trail that will link the community. Benches and educational kiosks will be located along the trail system.

5. 36 Homes will have rain barrels sized to treat a 1-inch rain event. Water collected by the barrels can be re-used for gardens and lawn and will help reduce stormwater runoff from the roof of the residence.

6. A community pavilion featuring a green roof and solar panels.

Among the most notable environmentally sensitive features of The Greens at Locust Chapel is its community pavilion. This community clubhouse and focal point includes a host of green building initiatives, including a fully planted green roof and special rainwater retention and re-use features. The community pavilion also includes a solar panel that helps reduce its use of energy from the community power grid. Other green features in the community include an electricity generating windmill, a community garden, timers on all exterior lights and permeable sidewalks and driveways that reduce erosion from rainwater runoff.
