ROADMAP PRIORITIES

• DOE will support roadmap activities that align
  with its mission Improving the energy
  efficiency, comfort and affordability of
  Buildings for the 21st century.
• DOE has begun to align many of its research
  activities with the Roadmap results.
• Manufacturers, architects, engineers, states, and
  utilities are encouraged to work with the
  Department, or individually, on the high-priority
  needs identified in the roadmap.
• The roadmap becomes a tool for communication and
  collaboration which enables industry and
  government to embark on joint projects

  ensure alignment with the roadmap and continues
  to explore ways for direct industry involvement
  including competitive RD solicitations.
• Key questions to address include
• What are the criteria for choosing projects (e.g.
  contribution, risk, energy savings)?
• What counts in aligning existing RD budget
  with roadmap?
• When do you collaborate on RD with logical
  champions?

41
DOE EVALUATION OF ROADAP PRIORITIES

• Technical Merit
• Energy, Environmental and Economic Benefit
• Commercial Potential
• Contribution to BT Strategy

OVERALL STRATEGY

• The strategy for technology roadmap
  implementation will insure progress, maintain
  consistency, and form an integrated plan for
  stakeholders, DOE program managers, and congress.
• The two major components of the strategy are
• Coordinate Continued Stakeholder Communication
• Implement Roadmap Components

45
COORDINATE CONTINUED STAKEHOLDER
COMMUNICATION(such as this meeting)

• Continued stakeholder communication is critical
  to ensure that the roadmaps are living documents.
  The implementation phase will
• Provide feedback on implementation plan process
• Allow channel for continuous roadmap updating
• Provide information on solicitation RFP
  announcements
• Facilitate the non-DOE roadmap components

46
IMPLEMENT ROADMAP COMPONENTS

• The components of each roadmap are being reviewed
  systematically to
• Identify what is already going on
• Prioritize the work do be done
• Decide/enlist logical champions for each effort
  (DOE, other government, Industry, or others)
• Make it happen! (funding, accountability)
• Already, this is underway and some initial
  results have been presented

47
THIS MEETINGSS OUTCOME

• Transparency of key DOE activities
• Feedback on overall strategy and program activity
• Key stakeholder input for establishment of high
  priority areas in upcoming solicitation
• DOE to examine areas to enhance public policy
