2. 2 K O V A R A Energy Consultants Why Monitor Energy Allows you to identify drifts in efficiency due to poor maintenance or operation Analysis of data often turns up new ideas for energy saving. It allows you to predict the savings to be expected from energy saving investments and actions. It gives you control of energy utilisation.

3. 3 K O V A R A Energy Consultants Links to energy MAP Commit Proof of success needed to maintain commitment Step 7: Key Factors Data analysis helps us to identify the key factors Step 8: Survey Large measuring element here Step 10: Targets Targets based on historical performance Step 17: Monitoring Step 18 provides the “How To”

4. 4 K O V A R A Energy Consultants Elements of Step 18 Record Normalise Analyse Target Monitor Report Control

5. 5 K O V A R A Energy Consultants Record: What plant to record? Consumption x “Slippage Potential” “Slippage Potential”: Poor maintenance Poor operation Raw material Efficiency Slip Potential

6. 6 K O V A R A Energy Consultants Record: What to measure Process Consumption / Yield meters ConditionIndicators

7. 7 K O V A R A Energy Consultants Record: What to measure Process Consumption / Yield meters ConditionIndicators Example: Air Compressors Meter Electricity Flow meter on compressed air Air off temperature Filter pressure loss Loaded and Unloaded hours

8. 8 K O V A R A Energy Consultants Record: What to measure Process Consumption / Yield meters ConditionIndicators Example: Chiller Meter Electricity Heat meter on chilled water Condensing temp – ambient temp Evaporator tem

9. 9 K O V A R A Energy Consultants Record: What to measure Process Consumption / Yield meters ConditionIndicators Example: Process CA Process compressed air flow meter Record production Identify the easily measurable factors that determine compressed air usage

14. 14 K O V A R A Energy Consultants Analyse: How? “First Principles” approach The core of energy monitoring is to derive a formula which gives the energy which should have been used for the period and compare the actual to this. Analyse Regression analysis

15. 15 K O V A R A Energy Consultants Analyse: Regression

16. 16 K O V A R A Energy Consultants Normalise: Secondary Drivers The concept of Secondary Drivers Examples: Air compressor (load pattern) Chiller (ambient temp, evaporating temp) Process (product weight, raw material, etc Normalisation factors usually come from the “First Principles” analysis

17. 17 K O V A R A Energy Consultants Target: On what basis? Recap: Each week compare ACTUAL with TARGET How to establish the Target: First principles, manufacturer’s data Regression analysis Industry benchmarks Use All Three: The “First Principle” gives you a good understanding of the process from which new ideas are born Regression is based on real data (credible) Benchmarks are important management information

18. 18 K O V A R A Energy Consultants Monitor: What it means 1 Each period check actual consumptions against targets 2 Check the “Condition Indicators”

19. 19 K O V A R A Energy Consultants Monitor: How often? How often should you collect the data and analyse it? Examples: Heating system: Monthly Chillers: Monthly Air Compressors:Monthly Process:Depends on the potential for “efficiency slippage” and its cost

20. 20 K O V A R A Energy Consultants Report: How detailed?

21. 21 K O V A R A Energy Consultants Control: Follow up From the report generate tasks/actions and formally ensure closure. [Why did it happen? What procedures are being put in place to ensure that it does not happen again?

23. 23 K O V A R A Energy Consultants Data Loggers

24. 24 K O V A R A Energy Consultants Data Loggers - Dent Time-Of-Use (TOU) SmartLoggers™ are small, battery powered activity data loggers. They store events like on/off transitions of lighting, motors and other electrical devices. They record and time stamp the actual time equipment turns on and off. The on/off transition times are stored in the data logger and the data are retrieved using the TOU SmartWare software. http://www.dentinstruments.com
