  4. ECAM—My View • Desktop Energy Information System • Energy Data Organizer • Energy Data Summarizer/Aggregator • Energy Data Analysis Tool • Now becoming an M&V Platform Over 8,000 lines of code Over 200 I/O controls

  5. ECAM Background • Initial building blocks and core code based on automation I developed for my personal use: • Disaggregation of Timestamps • Naming of fields • Automated chart creation and formatting • Time-series charts • Scatter charts • Calendar charts • 3d charts • Conversion of utility meter data tables to list format • A notable feature is the provision of scatter charts based on PivotTables

  6. ECAM Background • Formal development funded by NBI, NEEA and California (CEC, PIER, CCxC) • FREE Excel based tool • Currently Version 2.0 • Excel 2003/2007/2010 • Many more metrics, charts, and features • Supports PNNL “Re-Tuning” process • M&V enhancements in development,funded by NEEA.

  7. ECAM Incorporates Prior Research • Chart Types based on the PIER report, Web-based Energy Information Systems for Energy Management and Demand Response in Commercial Buildings (2003) http://www.energy.ca.gov/2003publications/CEC-500-2003-097/CEC-500-2003-097F-A13.PDF • Point Naming convention from A Specifications Guide for Performance Monitoring Systems http://cbs.lbl.gov/performance-monitoring/specifications/pdf/PM%20Spec%20Guide%20Version%201_2007-03-23.pdf

  9. LBNL EIS Survey June 2009Data Visualizations

  10. LBNL EIS Survey June 2009Data Visualizations • X-y scatter plotting was not a common or standard visualization capability in 2003, and while it has grown some it remains an under-supported feature in today’s EIS solutions. • Given their power in facilitating diagnostic troubleshooting it is discouraging that only half the tools surveyed include x-y plotting.

  11. ECAM Charting Features, partial list • Time series • X-Y (scatter charts from PivotTable!) • Daily load profile • 3D and Surface • Calendar load profiles • Box Plot Load Profiles • Schedule Input Confirmation

  12. ECAM Metrics • Daytype and Occupancy Metrics • Occupancy and Month-Year combination • Daytype and Month-Year combination • Frequency Distributions and Histogram • Data Summaries • Ratio of typical low to typical high demand • Percentiles: Max, 95, 90, 75, median, 25, 10, 5, minimum • Std. Deviations: Average, ±1, ±2, ±3

  13. ECAM Features • Automatic data pre-processing • Normalization • W/SF • cfm/SF • kW/ton • gpm/ton • Equipment status inferred from current or kW • Easy aggregation to totals/averages • Hourly • Daily • Monthly • Annual

  14. ECAM M&V, In Development • Scatter charts for daily totals/averages • Scatter charts for hourly totals/averages • Load Profile by Weekday (like RTU calculator, but with user choice of data point) • Daily scatter charts for each day of weekso users can easily see which days are similar • Easy ad-hoc definition of daytypes like RTU calculator • ‘Hourtypes’ based on input schedule

  15. ECAM M&V, In Development • Linear regression. • Change-Point regressions • 3-parameter • 4-parameter • 5-parameter • 6-parameter • Combine hourtype/daytype models into complete model

  16. ECAM M&V, In Development • Uncertainty Analysis • Residuals Analysis Charts • Annual extrapolation using TMY3 weather datalike RTU calculator

  17. M&V Output Charts

  18. M&V Output Charts

  19. Retuning Charts are Worksheet-Driven

  20. Load Duration Curve • Cumulative percentage of time at different loads. • For time period and daytype selected

  21. Load Frequency/Histogram • Actual time at different loads • For time period and daytype selected

  23. ECAM Can FacilitatePowerful Analyses “Bill, These plots are very telling… I wish I had some of these figures earlier. I just completed a textbook… wherein I would have liked to have included some of these figures.” T. Agami Reddy, Ph.D., Arizona State University
