  1. GrocerSmart™ 4.0 RTF Subcommittee Approval of Adherence to Guidelines March 10, 2011

  2. RTF Approval Schedule

  3. Today we will: • Discuss PECI’s validation of energy savings calculated by GrocerSmart 4 • Review PECI’s documentation format and approach to transparency

  4. Validation

  5. Time Operational Parameters Check Acceptable Ranges of Energy Savings

  6. Operational Parameters 1. Building Level 2. System Level 3. Component Level

  7. Operational Parameters 1. Building Level Validation Question: Is the modeled building functioning in an expected way? 2. System Level 3. Component Level Sources: Parameter: Grocery Energy Use Index (EUI) CBSA – Northwest Commercial Stock Assessment CBECS – Commercial Building End Use Survey

  8. Operational Parameters 1. Building Level Validation Question: Are building systems operating at expected levels as modeled? 2. System Level 3. Component Level Sources: Parameters: Normalized energy use Allocation CBECS – Commercial Building End Use Survey NC Modeling - 8 stores

  9. Operational Parameters 1. Building Level Validation Question: Are components operating with expected energy performance? 2. System Level 3. Component Level Sources: Parameters: Energy use/unit MAX energy use per component Metered Data Historic Program Data NC Modeling AHRI Others

  10. Time Operational Parameters Acceptable Ranges

  11. Acceptable Ranges

  12. Acceptable Ranges QuickNumber: 190 Used at point of customer contact to inform EE investment. Audit is processed by engineering team to determine correct savings and improve GS4.

  13. Calibration

  14. Calibration • Calibration strategy • What will be adjusted in template • What data will be used • Surveys • Utility-supplied data • M&V data • Studies

  15. Documentation

  16. Documentation • BDL Documentation • Template Code: Modeling code that is not dependant on audit information • Audit Object Code: Modeling code that is dependant on audit information • Measure Code: Changes made to baseline modeling code to simulate measures
