  • My personal experience with research paper writing services was highly positive. I sent a request to ⇒ www.WritePaper.info ⇐ and found a writer within a few minutes. Because I had to move house and I literally didn’t have any time to sit on a computer for many hours every evening. Thankfully, the writer I chose followed my instructions to the letter. I know we can all write essays ourselves. For those in the same situation I was in, I recommend ⇒ www.WritePaper.info ⇐.

  2. 2. Facing our Energy Challenges “The energy challenges our country faces are severe and have gone unaddressed for far too long. Our addiction to oil doesn’t just undermine our national security and wreak havoc on our environment – it cripples our economy and strains the budgets of working families all across America.” “President Obama and Vice President Biden have a comprehensive plan to invest in alternative and renewable energy, end our addiction to foreign oil, address the global climate crisis and create millions of new jobs.” White House Energy Statement “We're using 19th and 20th century technologies to battle 21st century problems like climate change and energy security.” Remarks of President Barack Obama, Signing of the American President Barack Obama Recovery and Reinvestment Act, February 17, 2009 1

  26. 26. How DOE works with private industry • Conducts competitive solicitations for direct funding, 20 percent cost share required • Formal agreements with National Laboratories, Cooperative Research and Development Agreements (CRADAs), protects existing intellectual property (IP) and manages new IP • Informal collaboration when IP is not an issue, support through testing, advice, etc - easy to get started • Case studies and partnerships 25
  27. 27. Major Areas of Unaddressed Opportunities • Competitive solicitations for private industry • R10 windows • In-depth performance validation and case studies • Dynamic envelopes • New Materials • Daylighting • Product development for products and techniques focused directly on the retrofit market 26
  28. 28. Key Conclusions • Envelope can play a major role to achieve ZEB • Greater industry role in setting priorities needed • Envelope industry interaction with the Federal government is limited • Global movement on climate and recent interest in Green construction could accelerate activity 27
