Solar Decathelon
October 9-18, 2009
National Mall in Washington

The U.S. Department of Energy sponsors the international Solar Decatehlon and this year's participants in DOE's 2009 Solar Decathlon will exhibit a range on new innovations in solar PV and solar thermal technologies -- as well as green building. 

The Solar Decathlon competition challenges students to design and develop houses that can provide their own energy from the sunlight - a clean, renewable source of energy.  

The twenty collegiate teams from the United States, Canada, Spain and Germany will each build a completely self-sufficient solar powered house, showcasing energy-efficient amenities and smart home systems that provide reduced carbon emissions without sacrificing the comfort of modern conveniences.

 "The Solar Decathlon highlights President Obama's goal of improving our national security and transforming the economy by using off-the-shelf, clean energy technologies to reduce our dependence on foreign sources of oil, reduce our carbon emissions, and protect the environment," said U.S. Energy Secretary Steven Chu.  "As part of the building competition, the next generation of green engineers, architects, designers, and professionals gain valuable experience that will help them to lead America toward a clean energy future."

DOE's Solar Decathlon, which takes place October 9-18 on the National Mall in Washington, D.C., consists of 10 individual contests that evaluate the teams' skills in architecture, home design, and communications. The homes constructed by the teams must produce enough electricity and hot water from solar panels to perform all the normal functions of a home -- from powering the lights; to cooking, washing clothes and dishes; to powering home electronics; and maintaining a comfortable temperature.  This year, a new net-metering contest will evaluate each home's ability to produce its own power.  The competition focuses on cutting edge energy efficient and renewable energy innovation while providing a unique green jobs training opportunity for each of the students.

The start of the competition marks the culmination of more than two years of hard work by the student teams.  The twenty teams will assemble their homes on the National Mall in early October.   Following the Opening Ceremony on October 8, the homes will be open for public tours October 9-13 and 15-18.

This is DOE's fourth Solar Decathlon competition since premiering in 2002 with subsequent competitions in 2005 and 2007.  On average, each Solar Decathlon competition has drawn more than 100,000 visitors to the National Mall.

The colleges and universities competing in the 2009 Solar Decathlon are:

  • Cornell University
  • Iowa State University
  • The Ohio State University
  • Penn State
  • Rice University
  • Team Alberta (University of Calgary, SAIT Polytechnic, Alberta College of Art + Design, Mount Royal College)
  • Team Boston (Boston Architectural College, Tufts University)
  • Team California (Santa Clara University, California College of the Arts)
  • Team Missouri (Missouri University of Science and Technology,  University of Missouri)
  • Team Ontario/BC (University of Waterloo, Ryerson University, Simon Fraser University)
  • Technische Universität Darmstadt
  • Universidad de Puerto Rico
  • Universidad Politécnica de Madrid
  • The University of Arizona
  • University of Illinois
  • University of Kentucky
  • University of Louisiana at Lafayette
  • University of Minnesota
  • University of Wisconsin-Milwaukee
  • Virginia Tech

The Solar Decathlon is sponsored by DOE's Office of Energy Efficiency and Renewable Energy, in partnership with its National Renewable Energy Laboratory, which manages the event.  For more information, please visit http://www.solardecathlon.org/.

The solar panels on top of the community center at Colonia San Martin, in Sacramento, CA is the newest project of the housing nonprofit Mercy Housing California, will produce six times more power than the average residential solar electric system. This is the first solar-power system on an affordable housing complex in Sacramento, and the housing complex was built in a partnership with the AIDS Housing Alliance.

An essential part of a total energy solution is to back up solar installations with energy efficiency so that the total amount of energy required for heating, cooling, and water service is optimized...before determining the size of the PV installation required or effective.

Each low income housing unit in this exemplary solar and efficiency project, has high-efficiency water heaters and heating, ventilation and air conditioning systems. The units  also have windows, insulation and radiant heat barriers rated to reduce energy use. The energy efficiency measures exceed California's Title 24 building codes for energy efficiency by at least 25%.  And that's significant because the Title 24 requirements include a 25% savings over conventional construction!

The 12-kilowatt solar PV system will generate an estimated 18,700 kilowatt-hours per year, cutting electric bills at the complex by an estimated $2,000 per year.

The photovoltaic solar system qualified for California state rebates, and SMUD (Sacramento Municipal Utility Department) negotiated a rebate package that helped the developer install the energy-efficient equipment.

Solar is a growing component of green building

| No Comments | No TrackBacks
Solar panels for photovoltaic energy and solar water heating have been steadfast components of green building design and construction.  That doesn't change in the 2009 update of the USGBC's green building LEED program. 

The U.S. Green Building Council is rolling out its new Leadership in Energy and Environmental Design (LEED) guidelines, updated for 2009 and newly approved by the USGBC membership.

Described as some of the most significant changes to the LEED system, LEED 2009 has re-weighted certain actions, based on scientific research, in favor of increasing energy efficiency and reducing carbon emissions in new and existing buildings. It also entails a new set of regional credits, which are points tailored to match environmental priorities in certain geographic areas.

The USGBC will also introduce new processes for amending its LEED standards, including a pilot period for individual credits that can be tested and incorporated on their own.

The nonprofit USGBC organization received more than 7,000 comments on how to update its 8-year-old, much-used green building rating system before LEED 2009 passed through its 18,000-member voting ballot.

McGraw-Hill Construction released a report in November 2008 that found the value of green building construction starts was up five-fold from 2005 to 2008.

According to the report, Green Outlook 2009: Trends Driving Change, starts were up from $10 billion in 2005 to $36 to $49 billion this year and could triple by 2013, reaching $96 to $140 billion.

The report is based on data found in the McGraw-Hill Construction Network and found that, since 2005, the perceived benefits of green building have increased as people become more informed about green building.

The decrease in operating costs is the most often cited benefit (13.6 percent, up from 8 percent to 9 percent in 2005),

Next is the increase in building values (10.9 percent, up from 7.5 percent in 2005).

The McGraw-Hill Cos. (NYSE: MHP) is a global information services provider with more than 280 offices in 40 countries and $6.8 billion in sales in 2007.
