Pump VFD Provisional Standard Protocol

1. Pump VFD Provisional Standard Protocol Regional Technical Forum June 18, 2013

2. Presentation Outline • Measure Overview • Staff Highlighted Areas • Presentation of Measure Documents • Standard Protocol Document • Research Plan Document • Standard Protocol Calculator • RTF Staff Recommendations • Proposed Decision

3. Measure Overview

4. Staff Highlighted Areas • Provisional research plan sample size: • RTF needed to weigh in on the sample size required by provisional research. • RTF staff recommends an initial sample size of 20 sites to understand variance between simplest reliable and best practice methods. • Provisional standard protocol calculator completion: • Calculator is still in the final stages of development and QC. • The decision today is to approve the pump VFD standard protocol contingent upon completion of calculator.

5. Standard Protocol Document • Open proposed standard protocoldocument and provide brief summary of measure definition, measure eligibility, and simplest reliable / best practice methods. • Summary of updates from subcommittee meeting: • General agreement that the protocol as constructed is applicable to enough potential projects to merit provisional standard protocol status. • Protocol expanded to include transfer pumps with on/off controls in the baseline period, as per subcommittee recommendation. • Staff proposed minor changes to improve document flow and add clarifications – subcommittee approved these changes.

6. Measure Research Plan • Open proposed research plan document • Remaining issue for RTF discussion: • To calculate a sample size, expected variance between Best Practices (BP) and Simplest Reliable Method (SRM) is necessary, but unknown. • This is necessary to calculate a sample size with an estimated confidence and precision that meet guidelines. • As per the guidelines “The SRM can be validated if either (a) it is free from substantial bias and agrees (+/- 20%) with the BPM at the individual site level; or (b) it is free from substantial bias and agrees (+/- 10%) with the BPM, on average, with 90% confidence” • Proposed solution: Collect data from a minimum of 20 sites to understand population characteristics. • Once this data is analyzed, informed decisions regarding sampling can be made. • We propose a sunset date of June, 2015 to allow for data collection and analysis.

7. Standard Protocol Calculator • Summary of calculator updates: • First round of QC conducted by Cascade Energy and RTF staff • Staff implementing improvements and additions identified through QC • Staff developing the calculator to be more user friendly (help, instructions) • Open proposed calculatorworkbook

8. RTF Staff Recommendations • Approve pump VFD standard protocol contingent upon completion of calculator • Completion of calculator will be determined by: • Expanding calculator to include transfer pumps with on/off controls in the baseline period as per subcommittee recommendation • Cascade Energy final QC finds that the calculator conforms to the protocol • Calculator posted for subcommittee review

9. Decision “I _________ move that the RTF approve the Pump VFD Protocol, Research Plan, and Calculator to: • Provisional Category; • Active Status; • a sunset date of June 30th, 2015 • provided that the calculator conforms to the Protocoland passes QC review.”
