  2. 2. LEED for HomesIt’s easier than you think
  3. 3. Energy Efficiency Disaster WaterMitigation EfficiencyEnvironmentally Site Friendly Materials Conditions Healthy Indoor Environment
  4. 4. The Parties in the Process:  The Provider  The Green Rater  The Energy Rater  The Project Team
  5. 5. The Parties in the Process:The Provider  An Entity Contracted by USGBC to Oversee Certification Process in a Specific Area  Trains and Coordinates Green Raters  Collects Fees for Project Registration and Certification  Provides Technical Support to Project Team and Green Raters  Reviews Certification Application Before Submission to USGBC
  6. 6. The Parties in the ProcessThe Green Rater  Individual Trained by a Provider to Conduct the Following Field Verification Inspections for Registered Projects: •Preliminary Rating •Pre-Drywall Inspection •Final Verification/Rating  Collects & Reviews Documentation for Certification Applications Before Submission to Provider
  7. 7. The Parties in the ProcessThe Energy Rater  Provides Preliminary HERS Rating for the Project  Conducts Several Key Field Tests •PreDrywall Envelope Leakage •PostDrywall Envelope Leakage •Duct Leakage
  8. 8. The Parties in the ProcessThe Project Team  Participates in the Initial Design Charrette to Develop Goals and Identify Challenges  Establishes Preliminary Rating  Meets Regularly Throughout Project to Assure Quality of Finished Product  Prepares Documentation for Submission to Green Rater
