This session examines challenges in coordinating data extracted from building automation systems with predictions from building energy models. With BEM increasingly informing design decisions, comparison to post-construction performance at the system level becomes key to troubleshooting and tuning. Discrepancies often first noted in whole-building energy use must be traced back to system level sources. Such comparison between BAS and BEM data is hindered by inconsistencies in data organization, naming, grouping and parameters. This issue is examined as a use-case for ASHRAE Guideline 20-2010, Documenting HVACR Work Processes and Data Exchange Requirements.
