2. Onga M&V activities for 12L – General approach
• General approach– Cut once, measure twice, and compare
• Measurement– Option A: Retrofit isolation (key parameter measurement)
– Option B: Retrofit isolation (all parameter measurement)
– Option C: Whole facility
– Option D: Calibrated Simulation
• Verification– Operational verification: confirm the ECM functionality
– Savings verification: confirm whether expected savings achieved

• FAQs:• Accessibility • Safety – SANAS requirements
3. Case study – M&V plan
Onga Energy Efficiency and Management (Pty) Ltd 14
• Project boundary– Furnace & the fan system
• M&V Option– Retrofit isolation: key parameter measurement
• Uncertainties– No sampling uncertainty since all fans are measured
– Handle measurement uncertainty
– Minimize modelling uncertainty
• Challenges– Selectin of the optimal M&V option
– M&V cost vs. uncertainty handling
3. Case study – Metering plan

FAQs:
• Applicability of historical baseline data?• Who provide the calibration service?• Cost of calibration?• When to calibrate?• Time required?• Validity period of calibration?• Does the calibrate happen in lab or in-situ?• Does all type of meters need calibration?
3. Case study – Data for baseline
• Collected data for baseline:– Fan energy usage: 01/10/2014 – 31/01/2015
– Fan operation schedule: 01/02/2014 – 31/01/2015 (12 months)
– Plant production data: 01/10/2014 – 31/01/2015
• Baseline period– Immediate 12 months before project implementation
– 01/02/2014 – 31/01/2015 (12 months)
• Calculation of baseline– Baseline energy profile: monthly energy usage in kWh
• FAQs– Review & revision process
