  1. BEDES-AUCStatus Update Bob Hendron and Michael Deru BEDESTWG Meeting February 25, 2014

  2. BEDES-AUC Project Overview • Objectives • Improve consistency of audit data collection and reporting • Provide a common language for data communication, analysis, and aggregation • Improve the quality and lower the long-term cost of audits • Strategies • Leverage existing databases, data forms, and data schemas • Integrate with the overall BEDES structure • Consider relationship of audit fields to other use cases • Obtain input from stakeholders • Technical Advisory Group (TAG) • Peer reviewers • Pilot project partners

  3. Project Timeline

  4. Overall TAG Mission and Schedule • Mission • Collaborate with NREL to develop a viable first draft of the BEDES-AUC • Advise NREL throughout development, piloting, and deployment of the BEDES-AUC • Schedule

  5. TAG Process • Electronic Review • Google Spreadsheet allows comments and edits from multiple reviewers in real time • Replies to comments indicate agreement or disagreement • If nobody expresses opposition to a comment, NREL makes the appropriate change without further discussion • Conference Calls • TAG reviews and comments on the relevant sections of the “strawman” during the week leading up to the call • Issues of significant controversy identified in “Comments” are discussed first, followed by an open forum

  6. Data Categories/Organization • BEDES Category • New Category

  7. Draft BEDES-AUC Data Fields • Launch Google Drive https://docs.google.com/spreadsheet/ccc?key=0AtHYfZ-jQvJ7dGJwSlo0VnBQcTRYaHV6NmVneVU3ekE&usp=drive_web#gid=0

  11. BEDES-AUC Measures Hierarchy (Draft)

  12. High Level Issues Deferred to BEDESTWG • What level of “implied” hierarchy should be used for data fields? (e.g. boiler pump efficiency, pump efficiency, or efficiency) • Should we require specific units, or allow alternative units to minimize errors? • What metadata fields are necessary for QA? (e.g. measured, default, estimated, nameplate) • Should calculated fields be included? If so, do we need to include the equations so they are calculated the same way by all users? • Should we establish constraints on numerical data (maximum/minimum, significant digits, etc.)
